An image on Instagram prompted the discovery of a new species of Kukri snake from Himachal Pradesh, India. Intrigued by a post shared by a master student, the research team found and examined more specimens to discover they belonged to a yet undescribed species. Their study, published in the open-access journal Evolutionary Systematics, highlights how little we still know about the biodiversity in the Western Himalayas.
Intrigued by a photo shared on Instagram, a research team from India discovered a previously unknown species of kukri snake.
Staying at home in Chamba because of the COVID-19 lockdown, Virendar K. Bhardwaj, a master student in Guru Nanak Dev University in Amritsar, started exploring his backyard, photographing everything he found there and posting the pictures online. His Instagram account started buzzing with the life of the snakes, lizards, frogs, and insects he encountered.
The snake, which Virendar encountered along a mud road on a summer evening, belongs to a group commonly known as Kukri snakes, named so because of their curved teeth that resemble the Nepali dagger “Kukri”.
At first sight, the individual that Virendar photographed looked a lot like the Common Kukri snake (Oligodon arnensis). However, a herpetologist could spot some unique features that raised questions about its identity.

Virendar uploaded the photo on 5 June 2020, and by the end of the month, after extensively surveying the area, he found two individuals – enough to proceed with their identification. However, the COVID-19 pandemic slowed down the research work as labs and natural history museums remained closed.
Upon the reopening of labs, the team studied the DNA of the specimens and found out they belonged to a species different from the Common Kukri snake. Then, they compared the snakes’ morphological features with data from literature and museums and used micro computed tomography scans to further investigate their morphology. In the end, the research team were able to confirm the snakes belonged to a species previously unknown to science.
The discovery was published in a research paper in the international peer-reviewed journal Evolutionary Systematics. There, the new species is described as Oligodon churahensis, its name a reference to the Churah Valley in Himachal Pradesh, where it was discovered.
What’s even more interesting is that the exploration of your own backyard may yield still undocumented species… if one looks in their own backyard, they may end up finding a new species right there.

“It is quite interesting to see how an image on Instagram led to the discovery of such a pretty snake that, until very recently, remained hidden to the world,” comments Zeeshan A. Mirza.

“What’s even more interesting is that the exploration of your own backyard may yield still undocumented species. Lately, people have been eager to travel to remote biodiversity hotspots to find new or rare species, but if one looks in their own backyard, they may end up finding a new species right there.”
“Compared to other biodiversity hotspots, the Western Himalayas are still poorly explored, especially in terms of herpetological diversity, but they harbor unique reptile species that we have only started to unravel in the last couple of years,” Mirza adds.

A new species of parasitoid wasp that constructs remarkable star-shaped cocoon masses is reported from the biodiversity hot spot Ryukyu Islands. Japanese researchers observed how the wasps construct “stars” after making their way out of the moth larvae they inhabit during their own larval stage. In their study, published in the open-access journal Journal of Hymenoptera Research, the team discuss the ecological significance of the cocoon mass and the evolution of this peculiar structure.

Parasitoid wasps parasitize a variety of organisms, mostly insects. They lay eggs in the host, a larva of hawk moth in this case, where the wasp larvae later hatch. After eating the host from the inside out, the larvae spin threads to form cocoons, in which they pupate, and from which the adult wasps eventually emerge.

Larvae of the newly discovered parasitoid wasp form star-shaped masses of cocoons lined up in a spherical pattern, suspended by a thread that can reach up to 1 meter in length. The structure, 7 to 14 mm wide and 9 to 23 mm long, can accommodate over 100 cocoons.

Despite its peculiarity, the wasp species constructing these masses had not been previously described: morphological observation and molecular analysis revealed that it was new to science. The authors aptly called it Meteorus stellatus, adding the Latin word for “starry” to its scientific name.
Thanks to the recent publication, we now have the first detailed report about the construction of such a remarkable cocoon mass in parasitoid wasps. We can also see what the process looks like, as the researchers were able to film the wasps escaping from the moth larvae and forming the star-shaped structure.
Why does M. stellatus form cocoons in such a unique structure?
The authors of the study believe this unique structure helps the wasps survive through the most critical time, i.e. the period of constructing cocoons and pupating, when they are exposed to various natural enemies and environmental stresses. The star shape most likely reduces the exposed area of individual cocoons, thus increasing their defense against hyper-parasitoids (wasps attacking cocoons of other parasitoid wasps), while the long thread that suspends the cocoon mass protects the cocoons from potential enemies like ants.
“How parasitoid wasps have evolved to form such unique masses instead of the common individual cocoons should be the next thing on our ‘to-research’ list,” say the authors.

For the first time in Slovakia, the dwarf spider Walckenaeria stylifrons and crab spider Spiracme mongolica were discovered on sand dunes in Záhorie Protected Landscape Area, on localities that serve as a military complex, used by the native Slovak army. Moreover, the spider W. stylifrons was found in a wine-growing region near the historical town of Modra.
European continental sand dunes, characterized by high ground temperature, high temperature fluctuations and movement of sand masses, belong to the rare, climatically extreme areas resembling deserts. In Europe, lowland sandy grassland habitats are considered to be among the most endangered and are often the subject of nature conservation.
The researchers decided to understand the spider assemblages living in such extreme habitats in Western Slovakia. During 2018–2019, the study sites were chosen and co-called pitfall traps hidden in the ground were used to collect spiders.
Among other collected species, two spiders were found for the first time in Slovakia. The dwarf spider W. stilifrons is recorded from 15 European countries and it is known from Eastern England to Eastern Germany in the north, and from the Iberian Peninsula to the Crimea and Cyprus in the south. Within Central Europe, the species has so far been known from Austria, Germany and Switzerland. The crab spider S. mongolica is known from Serbia to the European part of Russia. Its distribution in Asia extends from Central Asian part of Russia, Azerbaijan, Kazakhstan to Mongolia and China. In China it is known only from Western Inner Mongolia and Xinjiang region.
Crab spider, Spiracme mongolica
Upon the detailed examination of male copulatory organs, the researchers found out that one of the species shares characters typical for the genus Spiracme, in consideration of that a new combinationSpiracme mongolica for the spider previously known as Xysticus mongolicus was suggested.
In conclusion, the authors assume that W. stilifrons can live elsewhere in Europe. The rarity of the species may be related to the occurrence of adults, especially in the winter months, as most researchers are focused only on the growing seasons. The occurrence of S. mongolica in sand dunes in Slovakia confirms this species preference for dry habitats. The new finding of S. mongolica is the most known westernmost.

Discovery of the first moth species to mine the leaves of the highly poisonous Alpine rose

An Austrian-Swiss research team was able to find a previously unknown glacial relic in the Alps, the Alpine rose leaf-miner moth. It is the first known species to have its caterpillars specializing on the rust-red alpine rose, a very poisonous, widely distributed plant that most animals, including moths and butterflies, strictly avoid. The extraordinary record was just published in the peer-reviewed scientific journal Alpine Entomology.
Poisonous host plant
The rust-red alpine rose (Rhododendron ferrugineum) is among the best-known and most attractive plants due to its flowering splendor – at least for humans. It is, in fact, a highly poisonous plant, strictly avoided by grazing animals. For insects, the alpine rose is attractive at most as a nectar plant; insect larvae, on the other hand, develop on it only in exceptional cases. This also applies to Alpine butterflies and moths, which leave Alpine roses largely untouched despite their wide distribution. Therefore, the discovery of a highly specialized species in the Alps came as a complete surprise.
Chance find

Since alpine roses are unattractive to caterpillars and no insect the entire Alpine region was previously known to specialize on them, butterfly and moth experts had considered them rather uninteresting and ignored them in their research. The discovery of the alpine rose leaf-miner wasn’t the result of a targeted search: it was a pure stroke of luck.
During a cloudy spell in July this year, researchers surveying the butterflies in Ardez in the Engadine valley, Switzerland, happened to take a break exactly at an infested alpine rose bush.
“The accidental sighting of the first caterpillar in an alpine rose leaf was an absolute adrenaline rush, it was immediately clear that this must be an extraordinary species,”
Peter Huemer, researcher and head of the natural sciences department of the Tyrolean State Museums
Peter Huemer, researcher and head of the natural sciences department of the Tyrolean State Museums, and Swiss butterfly and moth expert Jürg Schmid came back in late July and early August to look for caterpillars and pupae and find out more about this curious insect. The extended search yielded evidence of a stable population of a species that was initially a complete enigma.
Life in the leaf

The alpine rose leaf-miner moth drills through the upper leaf skin and into the leaf interior immediately after the caterpillar hatches. The caterpillar then spends its entire life until pupation between the intact leaf skins, eating the leaf from the inside. Thanks to this behavior, the caterpillar is just as well protected from bad weather as from many predators such as birds, spiders, or some carnivore insects. The feeding trail, called a leaf mine, begins with a long corridor and ends in a large square-like mine section. The feces are deposited inside this mine. When the time comes for pupation, the caterpillar leaves the infested leaf and makes a typical web on the underside or a nearby leaf. With the help of several fine silk threads, it produces an elaborate “hammock”, in which the pupation finally takes place. In the laboratory, after about 10 days, the successful breeding to a moth succeeded, with a striking result.
Enigmatic glacial relic

Huemer and Schmid were surprised to find out that the moths belonged to a species that was widespread in northern Europe, northern Asia and North America – the swamp porst leaf-miner butterfly Lyonetia ledi. By looking at its morphological features, such as wing color and pattern, and comparing its DNA barcodes to those of northern European specimens, they were able to confirm its identity.

The Engadine population, however, is located more than 400 km away from the nearest other known populations, which are on the border of Austria and the Czech Republic. Furthermore, the species lives in northern Europe exclusively on swamp porst and Gagel bush – two shrubs that are typical for raised bogs and absent from the Alps. However, the researchers suggest that in earlier cold phases – some 22,000 years ago – the swamp porst and the alpine rose did share a habitat in perialpine lowland habitats north of the Alps. It is very likely that after the last cold period and the melting of the glaciers, some populations of the species shifted their host preference from the swamp porst to the alpine rose. The separation of the distribution areas of the two plants caused by subsequent warm phases inevitably led to the separation of the moth populations.
Extinction risk

The Alpine Rose Leaf-miner Moth is so far only known from the Lower Engadine. It lives in a steep, north-exposed, spruce-larch-pine forest at about 1,800 m above sea level. The high snow coverage in winter and the largely shady conditions in summer mean that alpine roses don’t get to bloom there. The scientists suspect that the moth species can still be discovered in places with similar conditions in the northern Alps, such as in neighboring Tyrol and Vorarlberg. Since the moth is likely nocturnal and flies late in the year, probably hibernating in the adult stage, the search for the caterpillars and pupae is more promising. However, the special microclimate of the Swiss location does not suggest that this species, which has so far been overlooked despite 250 years of research, is widespread. On the contrary, there are legitimate concerns that it could be one of the first victims of climate change.

Blog post by Dr. Marco Cirillo, Heart Failure Surgery Unit Director at the Cardiovascular Department in Poliambulanza Foundation Hospital (Brescia, Italy)
“Good morning, madam,” said the doctor greeting the patient who was entering his office.
“Good morning, Doctor,” she replied.
“So, how are you?” he asked her, motioning for her to sit in one of the two chairs in front of his desk.
“Well, it’s not bad.”
The doctor looked at her carefully.
“So, this first dose of chemo… Did you tolerate it well, right?”
“Yes, Doctor. I passed it…”
“Troubles? Nausea? Vomiting? Other problems?”
“No, Doctor. Nothing,” she replied.
The doctor continued to watch her carefully. After her last answer he got up and went to sit next to her in the other chair that was in front of his desk. He took her hand and asked her again:
“So, madam: how are you?“
The patient shook his hand as if in silent thanks.
“Doctor, you are a good doctor.”
“I’m here to understand what you need, madam, what can I do for you.”
The patient thought a little longer before speaking.
“So, Doctor: the chemo didn’t bother me much, maybe because it’s the first one. Except that… In short, what was difficult was waiting together with the others, all talking about their tumor, where they have it, what chemo they are at, what happened to them, then the hairless ones with the turban on their heads, and how much hemoglobin you have, and what your husband said, and if they recognized you without hair…”
“I understand, madam. But it’s also a way to exorcise it, isn’t it? A way to share this bad experience, to not feel alone…”
She looked him directly in the eyes.
“Doctor, we are not all the same. These things bother me. Seeing how I will be in a month scares me. It doesn’t solace me to know that someone is sicker than me. And knowing that someone is better terrifies me…”
The doctor nodded his head.
“I don’t want to think about my illness and when I come here, I necessarily think about it. I have to think about it. At home I do many things, I see many people, I may not think about it. But when I come here… Then for days I see these scenes in front of me, as if I’ve never left… Believe me, I do not simply ignore the disease, I know what I have and what awaits me. But if I could, I would avoid everything in between, between me and my illness. Do you understand?“
“Of course, madam. I understand. For others it is the same thing.”
They went silent for a while.
Then, the doctor said:
“If you had a choice, ma’am, what would you want? What would make you bear it all better?”
She answered immediately, as if she had the answer ready.
“If I could, I would like to fall asleep and wake up when it’s all over! Don’t see the others, don’t even see the hospital, don’t hear what the nurses say, don’t see the drip, don’t feel the needle entering, don’t see the drop of poison that I have to let into my body to try to survive… Don’t feel the time passing so slowly, as slow as the drop of the drip, a time ‘lost’ that is part of the little time I still have left… I am forced to hope that this time will pass quickly, but at the same time I know that it is not convenient for me to pass quickly, because even this time of treatment is taken away from my life. From what remains of it…“
The doctor released her hand and leaned back in his chair.
The lady asked him:
“Did I say something wrong?”
“No, madam, on the contrary,” said the doctor. “You told me something wonderful.”
“Ah, really? It sounds trivial to me…”
“No, what a patient says when he talks about himself and his illness is never trivial. You gave me a very good idea, madam.”
“Indeed?”
“Sure! What you ask can be done.”
“That is…”
“I can set up a study in which to administer chemo during sleep and analyze the results,” the doctor said, then corrected himself by translating his words into more direct language. “Sorry: I can make you sleep during the treatment, maybe set the treatment during night, so it doesn’t alter your days. And then you will wake up when it’s all over. That wouldn’t prevent some side effects…”
“…but it would prevent me from living consciously at the time of treatment,” the patient completed.
“Sure,” the doctor confirmed.
“Like the Sleeping Beauty…” the patient said. “You know the tale, don’t you?”
“Sure, who doesn’t know it.”
“The fairy godmothers cannot avoid the evil witch’s curse, so they make her fall asleep instead of die. Waiting for a solution,” the patient sighed deeply. “So, Doctor, if you can eliminate the evil that hangs over me, do it. Otherwise, let me sleep before the spinning wheel stings me.”
The doctor looked at her with a grateful look. He had always felt that not only did he do something for the patients every day, but the patients also did something for him every day.
“Would you do this for me, Doctor?”
The doctor smiled.
“Of course, ma’am. For you and for all the people who want it. Just give me some time to organize this.”
“Take your time” the lady said enthusiastically, but soon after she added with a wink: “No, on the contrary: hurry up, I wouldn’t want to waste any more time…”

Every doctor’s job is to heal diseases. When it is not possible to heal them, the best cure is to relieve the suffering. In Oncology, this second option is still extremely important. The psychological aspect of dealing with something that is often not guaranteed to heal is crucial.
This project aims to extend the concept of “care” by approaching the patient and his/her needs: it is not the patient who has to adapt to the hospital’s schemes, its timing, its protocols, but it is the hospital that must serve the patients, to “take care” after their problem in its multidimensionality.
The disease derails the life of the patient in a decisive way. We must as far as possible try to “sew in” the disease element into their everyday life, if we want them to experience it as something that is part of normal life. This can make them tolerate it better and perhaps improve the chances of overcoming it.
The study could be initially applied to a selected series of patients, and then extended, if the results are promising.
Certainly, there are some practical limitations related to this study. Arranging the administration during sleep requires many “beds”; it requires specialized nursing staff; if it is carried at home, it also needs allocating specialists for home visits.
It is true, however, that home care for cancer patients is already very common in advanced healthcare systems. Economic investment and funding of cancer research and treatment remain at the top, along with cardiovascular diseases, in all healthcare systems.
Cancer Centers nowadays abound around the world and are increasing in numbers. Comprehensive Cancer Centers, which are the largest in America, carry out transdisciplinary research, recognizing the importance of integrating different knowledge together for more effective treatment. The assistance and therapeutic network, the shared protocols, the sector research in Oncology already boast a very high level today. The coordination between centers makes use of all that assistance know-how. If I have to think of a medical field in which research, assistance, network of knowledge and uniformity of treatment are the most coordinated and efficient, this field is undoubtedly the oncology one.
I would gladly give my scientific contribution by collaborating with centers of Excellence and their teams, who would like to join me on this research project. I would also readily share some organizational ideas by integrating them with the specific knowledge of colleague oncologists. Let’s fight the curse and help people to bear it with the least physical and psychological suffering!

Having decided to turn Tūhinga “into a 21st-century”, digital-native diamond open-access journal, the Museum of New Zealand Te Papa Tongarewa signed with scholarly publisher and technology provider Pensoft and its publishing platform ARPHA. As part of their agreement, not only is the journal to make its future content easy to read and discover by readers and computer algorithms, but will also do so for its legacy content.
Having decided to turn Tūhinga “into a 21st-century”, digital-native diamond open-access journal, the Museum of New Zealand Te Papa Tongarewa signed with scholarly publisher and technology provider Pensoft and its publishing platform ARPHA. As part of the agreement, not only is the journal to make its future content easy to read and discover by readers and computer algorithms, but will also do so for its legacy publications previously available solely in print.
Tūhinga: Records of the Museum of New Zealand Te Papa Tongarewa is the successor of the Museum of New Zealand Records, the National Museum of New Zealand Records, and the Dominion Museum Records in Ethnology. Together, the outlets have acquired a nearly two century-worth of scientific knowledge provided by the museum’s curators, collection managers, and research associates across disciplines, from archaeology to zoology.
The renovated Tūhinga is to utilise the whole package of signature services provided by the platform, including ARPHA’s fast-track, end-to-end publishing system, which benefits readers, authors, reviewers and editors alike.
This means that each submitted manuscript is to be carried through the review, editing, publication, dissemination and archiving stages without leaving the platform’s collaboration-centred online environment. The articles themselves are to be openly available in PDF, machine-readable JATS XML formats, and semantically enriched HTML for better reader experience. Thus, the journal’s articles will be as easy to discover, access, reuse and cite as possible. Once published, the content is to be indexed and archived instantaneously and its underlying data exported to relevant specialised databases. Simultaneously, a suite of various metrics is to be enabled to facilitate tracking the usage of articles and sub-article elements – like figures and tables – in real time.
The journal’s legacy content is to also become machine-discoverable and more user-friendly. Each of these papers will also be assigned with DOI and registered at CrossRef, while their metadata will be indexed at relevant databases. On the new journal website, they will be displayed as embedded PDF documents, while the reader will be able to do a full-text search of the article’s content.
Tūhinga welcomes original collections-based research in the natural sciences and humanities, including museological research, where its multidisciplinarity reflects the breadth and range of museum-based scholarship. The journal focuses primarily on New Zealand and the Pacific, but all contributions are considered. Having opted for a Diamond Open Access policy, the journal is to charge neither its readers, nor the authors.
“It’s a great honour to sign with the Museum of New Zealand Te Papa Tongarewa and provide our publishing services to Tūhinga. Particularly, we take pride in letting the whole wide world straight into the holdings of Te Papa and the knowledge they have prompted in the distant past: something that would not typically be possible had they remained only on paper,”
says Prof. Dr Lyubomir Penev, founder and CEO at ARPHA and Pensoft.
Herpetozoa, the peer-reviewed scientific journal of the Austrian Herpetological Society, renewed its contract with Pensoft, re-signing with the scholarly publisher for another five years. Published since 1988, the journal offers a venue for research articles, short contributions and reviews dealing with all aspects of the study of amphibians and reptiles.
Herpetozoa, thepeer-reviewed scientific journal of the Austrian Herpetological Society, renewed its contract with Pensoft, re-signing with the scholarly publisher for another five years. Published since 1988, the journal offers a venue for research articles, short contributions and reviews dealing with all aspects of the study of amphibians and reptiles.
Enticed by the opportunities that open access publishing offers, and looking to improve its visibility, Herpetozoa first came to Pensoft in 2019. The move equipped the journal with abrand new website and a full suite of publishing services tailored to the needs of biodiversity-themed academic publications available from ARPHA, Pensoft’s self-developed publishing platform.
In ARPHA’s fast-track publishing system, each manuscript is carried through all stages, from submission and reviewing to dissemination and archiving, without ever leaving the platform’s collaboration-friendly online environment. In addition, semantic enhancements, automated data export to aggregators, web-service integrations with major indexing databases, and a variety of publishing formats ensure that all articles are easy to find, access, and use by both humans and machines.
The journal also makes use of ARPHA Preprints, another service developed by Pensoft to streamline public access to the latest scientific findings. The platform allows authors to submit a preprint in a matter of seconds along with their manuscript, with no need to upload any additional files. Following a quick in-house screening, the preprint is then made available on ARPHA Preprints in a few days’ time. Once the associated paper is published, a two-way link between the article and the preprint is established via CrossRef.
In the past three years, we saw Herpetozoa publish some quite peculiar discoveries that were quick to attract the attention of the global media. Such was the case of a set of first-of-their-kind observations of kukri snakes gutting toads and eating their organs while still alive. At the same time, the journal doesn’t fail to bring public attention to urgent conservation and biodiversity loss issues like reptile poaching in Pakistan, as well as innovative methods to monitor delicate amphibians in a non-invasive manner.
The first phase of the EU initiative to map and provide new insights into the gaps of taxonomic expertise is about to close. The decisive next stage of analysis begins with the assessment of the collected self-registered taxonomists against the Red List criteria.
The first phase of the EU initiative to map and provide new insights into the gaps of taxonomic expertise is about to close. The decisive next stage of analysis begins with the assessment of the collected self-registered taxonomists against the Red List criteria.
For the past five months, the European Commission-funded project ‘European Red List’ of Taxonomists has been reaching out to insect taxonomists to invite them to register at the Red List of Taxonomists portal.
Behind the project are the organisation uniting the most important and largest European natural science collections (CETAF), the world’s authority on assessing the risk of extinction of organisms: the International Union for Conservation of Nature (IUCN) and the scientific publisher with a long history in the biodiversity and ecology fields Pensoft.
“It’s never been as clear that the sustainability of our ecosystems and economies are tightly connected to how healthy our pollinators and other insects within the intricate web of life are. So, it is obvious that securing the constant flow of scientific knowledge shall be of utmost importance to everybody,”
say the project partners.
“At the end of the day, it’s the experts who identify insects and investigate their abundance and diversity that are best equipped to inform the community – including the key decision-makers – about things like what native species are in urgent need of protection, which ones have recently started to diminish, and how to spot invasives well known for their harm on local biodiversity. The major problem, however, is that these experts are rapidly declining themselves.”
Having filled in their details, such as country of residence and activity, institutional affiliation, seniority and insect group of interest, over 1,200 participants provided valuable data necessary to estimate the actual number, location and profile of the insect taxonomists based or working in Europe. The final report – to be released in early 2022 – will also present past and future trends of expertise within the continent and across insect taxa. A comprehensive list of recommendations will shed light on where and what support is needed to prevent the ‘extinction’ of experts and their invaluable contributions to evidence-based conservation efforts.
In particular, the final recommendations are to highlight all key measures and tools expected to bridge the identified gaps at both national and pan-European level, including the use of relevant funding programmes. The report will also include an estimate of the associated efforts and costs.
Developing below the soil surface, desert truffles are hard to find. Recently, researchers of the University of Évora updated the number of known species of the desert truffle genus Terfezia occurring in Portugal from three to ten species. They thoroughly characterized their ecological preferences, adding new knowledge on Terfezia’s cryptic lifestyle. These findings are of major importance, as desert truffles have a high economic value. The study was published in the open-access journal MycoKeys.
In a caring, symbiotic relationship, mycorrhizal fungi live and feed in the roots of specific plants, while providing water and nutrients to their ‘companion’. In arid and semi-arid environments, mycorrhization processes are essential to the survival of both plants and fungi. Moreover, the fungus’ hyphal network, which spreads within the soil connecting several plant individuals, is of utmost importance to enhancing soil quality and fertility.
Researchers of the University of Évora in Portugal, led by biologist Celeste Santos e Silva, worked on Terfezia fungi, the most diverse and species-rich genus among desert truffles. Their study, published in the open-access journal MycoKeys, might prove particularly valuable to rural populations in the Mediterranean basin, where desert truffles, highly valued in local markets, are an important food source. Increasingly turning into an exquisite component of the Mediterranean diet, Terfezia products can also be very profitable. Furthermore, these fungi are essential for soil conservation, preventing erosion and desertification.
Desert truffles.
After 8 years of exhaustive field exploration in search of desert truffles and many hours in the molecular biology lab, the researchers noted some previously unknown trends in the ecology of Terfezia species. They recorded seven species that were new to Portugal, including two that are new to science – Terfezia lusitanica and Terfezia solaris-libera. This brings the number of Terfezia species known to be growing in the country to ten. Particularly important was the discovery of a broader ecological range for many of the studied species (e.g. Terfezia grisea). Adding valuable information about their possible hosts, symbionts and ecological constraints, these findings help open new opportunities for truffle cultivation.
“It is very difficult to identify all specimens given that the Terfezia species look so much alike, and molecular biology was absolutely fundamental here”, explains the researcher. “The technique was essential to update and solve problems about their taxonomy and the relationship between the species in the genus.”
Furthermore, the discoveries are also expected to positively impact the local communities by stimulating agriculture produce, business and even employment.

Knowledge gained in this research about the conditions in which different Terfezia species grow is an important step to desert truffle cultivation: the fungi are hard to find in the wild, which is why it would make a big difference – including financially – for local communities if they figure out a way to grow truffles themselves.
Within the project “Mycorrhization of Cistus spp with Terfezia arenaria (Moris) Trappe and its application in the production of desert truffles” (ALT20-03-0145-FEDER-000006), the researchers took a step forward towards achieving mycorrhizal association of desert truffles with perennial plants (rock roses), which would allow their mass production for various sectors such as food, medicine and soil recovery. This new form of production, assures the MED researcher and leader of the project, “will make it possible to create more jobs, reversing the current trend towards desertification in rural areas, while being a great tool for ecosystem recovery and restoration”.

… and 27 other new species of beetles discovered on Sulawesi Island
Many curious animals can be found on the Indonesian Island of Sulawesi – such as the deer-hog and the midget buffalo. But the island’s tropical forests hide a diversity of tiny insects that still remains largely unexplored. Museum scientists from Indonesia and Germany have just discovered 28 new species of beetles, all belonging to the weevil genus Trigonopterus.

Most of the new species were collected by Raden Pramesa Narakusumo, curator of beetles at the Museum Zoologicum Bogoriense, from two localities of Central Sulawesi Province: Mt. Dako and Mt. Pompangeo. In fact, the forests on their slopes had never been searched for small weevils before.

His research partner, Alexander Riedel of the Natural History Museum Karlsruhe, had been studying this genus for the past 15 years and was planning for a research trip to Papua New Guinea, when the COVID-19 pandemic hit. Finding himself grounded, he decided to work on the specimens from Sulawesi together with Narakusumo instead.
After diagnosing the new species, it was a challenge to find suitable names for them. One obvious choice was Trigonopterus corona, which reflects the large impact of the COVID-19 pandemic on this project. However, T. corona is by far not the first insect species with a pandemic-inspired name. In the last year, we’ve seen the species descriptions of the caddisfly Potamophylax coronavirus and the wasps Stethantyx covida and Allorhogas quarentenus.

While some of the newly described species go by rather ‘standard’ names that derive from either the localities they have been collected from or their distinct characters, others were given a free pass to the Hall of Fame. Two of them were named after Indonesian movie characters (T. gundala and T. unyil), while T. ewok is another addition based on the Star Wars universe – perfectly in line with T. chewbacca, T. yoda and T.porg, all described between 2016 and 2019 by teams involving Riedel. The two-millimeter-long, rust-coloured Trigonopterus ewok was found at 1900–2000 m on Mt Pompangeo, hiding among the leaf litter in the forest.
But how come the critters have remained overlooked for so long? Almost all of these beetles measure only 2-3 millimeters, while most entomologists have a preference for the larger and strikingly looking stag beetles or jewel beetles.
A second factor is the superficial resemblance of many species: they are most easily diagnosed by their DNA sequences. Besides the publication in the open-access journal ZooKeys, high-resolution photographs of each species were uploaded to theSpecies ID website, along with a short scientific description. This provides a face to the species name, an important prerequisite for future studies.

This is the duo’s second published paper on Trigonopterus weevils from Sulawesi – the first one describing the whopping 103 new species from the area. Currently, the known Trigonopterus species on the island amount to 132, which is likely a mere fraction of the real diversity. The numerous mountains of Sulawesi have a distinct fauna of endemics that have evolved over the past millions of years, and these wingless, flightless weevils, highly isolated in their habitats, are a good example of this diversification. Their evolution is interwoven with the island´s geological history. Riedel wants to increase the number of sampled localities:
“Once we have enough locality coverage and understand the weevils’ evolution, we can draw conclusions on the geological processes that formed the island of Sulawesi. This is a fascinating subject, because this island was formed by the fusion of different fragments millions of years ago.” The new species thus fill an important gap required for solving the island´s geological puzzle.
For the Indonesian side, it is equally important to obtain an inventory of species: “A large percentage of Indonesian biodiversity is yet unknown and we need names and diagnoses of species, so we can use these in further studies on conservation and bioprospecting,” says R. Pramesa Narakusumo. “Two of the newly described species came from our museum collection, and this underlines the importance of museums as a source for biological discoveries,” he added.
With many more new species of this genus to be expected, it is a lucky coincidence that the number of Star Wars characters is equally long. May the Force be with these researchers!
