Second of its kind ‘sharpshooter’ leafhopper from Brazil ‘strikes’ with its colouration

When, in 2014, Brazilian researchers stumbled across a never-before-seen red-eyed leafhopper feeding inside the rosettes of bromeliads, growing in the restingas of southeastern Brazil, they were certain it was a one-of-a-kind discovery. Described as new-to-science species, as well as genus (Cavichiana bromelicola) and added to the sharpshooter tribe Cicadellini, it became the first known case of a leafhopper feeding on otherwise nutrition-poor bromeliads in their natural habitat.

Several years later, however, a team of entomologists from Universidade Federal do Rio de Janeiro carried out fieldwork in a mountainous area of southeastern Brazil and, as a result, another bromelicolous leafhopper species of the genus was discovered: Cavichiana alpina. Only, the new one appeared even more spectacular. 

The new species, described and illustrated in the open-access journal Zoologia, is known from Itatiaia National Park (southeastern Brazil), where it can be found at altitudes above 1,800 m a.s.l. In fact, its characteristic mountainous habitat came to determine its species name (alpina). In contrast, its relative was originally described exclusively from sea level regions, even though the latest field trips have recorded it from a site located at 1,250 m a.s.l. 

Slightly larger than the previously known C. bromelicola and similarly red-eyed, what most remarkably sets apart the newly-described species is its colouration. Rather than a single large yellow blotch contrasting against the dark-brown to black back of the insect, this sharpshooter sports a motley amalgam of red and blue covering most of its upper side.

In conclusion, the researchers explain that the peculiarity of the two known Cavichiana species is best attributed to a putative common ancestor that had likely once been widely distributed in southeastern and southern Brazil. Later, they speculate, a vicariant event, such as the uplift of the southeastern Brazilian mountain ranges during the latest Eocene and Oligocene, might have caused its diversification into two separate species.

While monitoring of cryptic and elusive tiny creatures, such as pygmy seahorses that measure only 13 to 27 mm, might be too costly and time-consuming for research teams and institutions, the underwater activity might be proving of particular interest to photography and diving enthusiasts.

At least, this is what comes across from the recent reports of five miniature species identified from Taiwanese waters by local citizen scientists and passed along via Facebook and Instagram. Amongst the findings, there are two species that had never before been reported from the country, including last year’s media sensation: the ‘Japan pig’, considered to only be found in the “Land of the Rising Sun”. The study, conducted by the team Mr. Joseph Heard,  Drs Jeng-Ping Chen and Colin Wen from Tunghai University and Taiwan Ocean Research Institute, is published in ZooKeys, the very same open-access journal that saw the description of the species in 2018.

The scientists note that pygmy seahorses are largely unknown species and even basic information regarding their habitats is largely inconsistent and based on unofficial reports. As monitoring of marine wildlife can be expensive and time-consuming, especially regarding its small and cryptic representatives, the researchers decided to use “Phone a Friend” lifeline. Scuba divers and underwater photographers were approached on social media to help investigate pygmy seahorse diversity in Taiwan.

Their call resulted in 259 social media items, including 75 photos of 78 miniature creatures from their natural habitats at five different locations. Identified as five separate species, their discovery ranks Taiwan as one of the world’s biodiversity hotspots for pygmy seahorse, given that there are only seven species of pygmy seahorses out there.

Four of those were found at Green Island alone, a small volcanic Pacific island, measuring only 15 km2. 

Pygmy seahorse specimen collection from Taiwan for future examination is still undergoing.

UCF student names a new frog species after her professor

The team described two new species from the Ecuadorian Andes

University of Central Florida student Veronica Urgiles has helped describe two new frog species discovered in Ecuador, and she named one of them after one of her professors.

Urgiles and an international team of researchers published their findings in the journal ZooKeys.

UCF student Veronica Urgiles named one of the new frog species in honor of Biology Professor Pedro Quintana-Ascencio for his years of dedication to conservation efforts in Ecuador.

She explains:

“Frogs are by far my favorite. So, getting to describe and name two of them is terrific. I have been looking at these frogs for years now, so going over the whole process of observing them in their habitats and then analyzing them and comparing them under the microscope, to finally naming them is a long, but very satisfying journey.”

Urgiles, a 2017 Fulbright scholar and the lead author, said she chose to attend UCF for its integration of genetics and genomics in biodiversity research and the emphasis on real-world application. She works with Assistant Professor Anna Savage who specializes in species diversity based on molecular analyses.

“One of the things that I found most interesting about these guys is that they don’t have metamorphosis like a regular frog, but instead they develop entirely inside eggs that adult females deposit in the ground,” Urgiles said. “They really don’t need water bodies for their development. Both of the new frog species inhabit high elevation ecosystems in the mountain range over 8,000 feet, so even though we are right there in the equator, it’s very cold and windy most of the year.”

The team of researchers has been studying frogs in Ecuador the past few years. In 2017, Urgiles found the first new species and named it Pristimantis quintanai, after one of her biology professors — Pedro Quintana-Ascencio. She and Savage found the second species — Pristimantis cajanuma — in 2018. Both were found in the Paramo and montane forest of the southern Ecuadorean Andes.

The frogs are tiny, measuring 0.8 inch. Pristimantis quintanai females are brown and black and Pristimantis cajanuma are green and black, both easily blending into the foliage. They have a distinct call that is sharp and continuous, sounding like tik-tik-tik-tik.

Urgiles examined DNA samples collected by the international team back in Savage’s lab at UCF, generated genetic sequences, and constructed the phylogenetic analysis. Other team members also worked the morphological diagnosis and comparisons with other frogs and an acoustic analysis of the frogs’ calls.

Anna Savage, whose expertise includes describing species diversity based on molecular analyses, says:

“In these analyses, we use all of the genetic similarities and differences we find to build phylogenetic trees, and when we find that a ‘branch’ on the ‘tree’ has strong support and contains all of the individuals that share the same morphological characteristics, then we have good evidence to describe it as a new species. We used this method, along with vocalization and location data, to conclude that the two species we describe are distinct from any other species that have ever been characterized.”

The work is critical because of the vast diversity that has yet to be discovered in the tropical Andes of South America, Urgiles adds. In 2018, 13 new species of frogs were documented in the tropical Andes of Ecuador and so far in 2019 five new frogs have been documented.

There are potentially thousands of new plants and animals in the area that may hold the key to other discoveries. It’s important to know what is there, to better understand the threats to habitat loss and disease so conservation methods can be established to protect the resources.

New species of flying squirrel from Southwest China added to the rarest and ‘most wanted’

Described in 1981, the genus Biswamoyopterus is regarded as the most mysterious and rarest amongst all flying squirrels. It comprises two large (1.4-1.8 kg) species endemic to southern Asia: the Namdapha flying squirrel (India) and the Laotian giant flying squirrel (Lao PDR). Each is only known from a single specimen discovered in 1981 and 2013, respectively.

Recently, in 2018, a specimen identifiable as Biswamoyopterus was unexpectedly found in the collections of the Kunming Institute of Zoology (KIZ), Chinese Academy of Sciences by in-house expert Quan Li. It had been collected from Mount Gaoligong in Yunnan Province, Southwest China.

Initially, the individual was considered to belong to the “missing” Namdapha flying squirrel: a species considered as critically endangered due to hunting and habitat loss. The latter had not ever been recorded since its original description in 1981 and was already listed as one of the top 25 “most wanted” species in the world by the Global Wildlife Conservation.

However, a closer look at the specimen from KIZ made it clear that the squirrel exhibited a colouration, as well as skull and teeth anatomy, distinct from any of the previously known species in the genus.

Subsequently, joined by his colleagues from China (Xuelong Jiang, Xueyou Li, Fei Li, Ming Jiang, Wei Zhao and Wenyu Song) and Stephen Jackson from Australia, the team of Quan Li conducted a new field survey. Thus, they successfully obtained another specimen and, additionally, recorded observations of two other flying squirrels. As a result, they included a third member to the enigmatic genus: Biswamoyopterus gaoligongensis, also referred to as the Mount Gaoligong flying squirrel. This new to science species was described in a paperpublished in the open-access journal ZooKeys.

“The morphological features of B. gaoligongensis are closer to the critically endangered and missing Namdapha flying squirrel, but is still readily identifiable as a distinct species,” explains Quan Li.

“The new species was discovered in the ‘blank area’ spanning 1,250 km between the isolated habitats of the two known species, which suggests that the genus is much more widespread than previously thought. There is still hope for new Biswamoyopterus populations to be discovered in between or right next to the already known localities,” he says.

As for the conservation status of the newly described species, the researchers note that it inhabits low-altitude forests which are in close proximity to nearby human settlements. Thereby, they are vulnerable to anthropogenic threats, such as agricultural reclamation and poaching.

“Therefore, there is an urgent need to study the ecology, distribution, and conservation status of this rare and very beautiful genus,” concludes the lead author.

Wakanda Forever! Scientific divers describe new purple species of “twilight zone” fish from Africa

Named for Black Panther’s mythical nation of Wakanda, a dazzling new “Vibranium” Fairy Wrasse enchants with purple scales and a preference for deep, little-known mesophotic reefs up to 260 feet below the surface

Africa has new purple-clad warriors more than 200 feet beneath the ocean’s surface. Deep-diving scientists from the California Academy of Sciences’ Hope for Reefs initiative and the University of Sydney spotted dazzling fairy wrasses—previously unknown to science—in the dimly lit mesophotic coral reefs of eastern Zanzibar, off the coast of Tanzania.

The multicolored wrasses sport deep purple scales so pigmented, they even retain their color (which is typically lost) when preserved for research. The scientists name this “twilight zone” reef-dweller Cirrhilabrus wakanda (common name “Vibranium Fairy Wrasse”) in honor of the mythical nation of Wakanda from the Marvel Entertainment comics and movie Black Panther. The new fish is described in the open-access journal Zookeys.

Yi-Kai Tea, lead author and ichthyology PhD student from the University of Sydney, says:

“When we thought about the secretive and isolated nature of these unexplored African reefs, we knew we had to name this new species after Wakanda. We’ve known about other related fairy wrasses from the Indian Ocean, but always thought there was a missing species along the continent’s eastern edge. When I saw this amazing purple fish, I knew instantly we were dealing with the missing piece of the puzzle.”

The Academy scientists say Cirrhilabrus wakanda’s remote home in mesophotic coral reefs—below recreational diving limits—probably contributed to their long-hidden status in the shadows of the Indian Ocean.

Therefore, Hope for Reefs’ scientific divers are highly trained for the dangerous process of researching in these deep, little-known mesophotic reefs, located 200 to 500 feet beneath the ocean’s surface. Accessing them requires technical equipment and physically intense training well beyond that of shallow-water diving. The team’s special diving gear (known as closed-circuit rebreathers) includes multiple tanks with custom gas blends and electronic monitoring equipment that allow the divers to explore deep reefs for mere minutes before a lengthy, hours-long ascent to the surface.

Dr. Luiz Rocha, Academy Curator of Fishes and co-leader of the Hope for Reefs, comments:

“Preparation for these deep dives is very intense and our dive gear often weighs more than us. When we reach these reefs and find unknown species as spectacular as this fairy wrasse, it feels like our hard work is paying off.”

Using a microscope, the team examined the specimens’ scales, fin rays, and body structures. DNA and morphological analyses revealed the new fairy wrasse to be different from the other seven species in the western Indian Ocean as well as other relatives in the Pacific. The new species’ common name is inspired by the fictional metal vibranium, a rare, and, according to Rocha, “totally awesome” substance found in the nation of Wakanda. The Vibranium Fairy Wrasse’s purple chain-link scale pattern reminded the scientists of Black Panther’s super-strong suit and the fabric motifs worn by Wakandans in the hit film.

Precious life in deep reefs

In a recent landmark paper, the Academy team found that twilight zone reefs are unique ecosystems bursting with life and are just as vulnerable to human threats as their shallow counterparts. Their findings upended the long-standing assumption that species might avoid human-related stressors on those deeper reefs. The Hope for Reefs team will continue to visit and study twilight zone sites around the world to shed light on these often-overlooked ecosystems.

In addition to this new fish from Zanzibar, Rocha and his colleagues recently published descriptions of mesophotic fish from Rapa Nui (Easter Island) and Micronesia. Luzonichthys kiomeamea is an orange, white, and sunny yellow dwarf anthias endemic to Rapa Nui, and the basslet Liopropoma incandescens (another new species published today in Zookeys) inhabits Pohnpei’s deep reefs—a neon orange and yellow specimen collected from a rocky slope 426 feet beneath the ocean’s surface.  

“It’s a time of global crisis for coral reefs, and exploring little-known habitats and the life they support is now more important than ever,” concludes Rocha. “Because they are out of sight, these deeper reefs are often left out of marine reserves, so we hope our discoveries inspire their protection.”

Two new species of parasitic wasps described from an altitude of over 3,400 m in Tibet

Specimens kept in the collection of the Institute of Beneficial Insects at the Fujian Agriculture and Forestry University (FAFU, China) revealed the existence of two previously unknown species of endoparasitoid wasps. Originally collected in 2013, the insects are known to inhabit prairies and bushes at above 3,400 m, which is quite an unusual altitude for this group of wasps.

The new to science wasps are described and illustrated in a paper published in the open-access, peer-reviewed scholarly journal ZooKeys by the team of Dr Wangzhen Zhang (FAFU and Fuzhou Airport Inspection and Quarantine Bureau) and his colleagues at FAFU: Dr Dongbao Song and Prof Jiahua Chen.

Looking very similar to each other, the species were found to belong to one and the same genus (Microplitis), which, however, is clearly distinct from any other within the subfamily, called Microgastrinae. The latter group comprises tiny, mostly black or brown wasps that develop in the larvae of specific moths or butterflies. Interestingly, once parasitised, the host continues living and does not even terminate its own growth. It is only killed when the wasp eggs hatch and feed on its organs and body fluids before spinning cocoons.

From now on, the newly described wasps will be called by the scientific names Microplitis paizhensis and Microplitis bomiensis, where their species names refer to the localities from where they were originally collected: Paizhen town and Bomi county, respectively.

Due to their parasitism, some microgastrine wasps are considered important pest biocontrol agents. Unfortunately, the hosts of the newly described species remain unknown.

In addition, the scientists also mention a third new to science species spotted amongst the specimens they studied. However, so far they have only found its male, whereas a reliable description of a new microgastrine wasp requires the presence of a female.

New to science New Zealand moths link mythological deities to James Cameron’s films

In an unexpected discovery from New Zealand, two species of narrowly distributed moths were described as new species. Interestingly, both Arctesthes titanica and Arctesthes avatar were named after mythological deities and top-grossing blockbusters by famous filmmaker James Cameron: Titanic and Avatar, respectively.

In an unexpected discovery from the South Island (New Zealand), two species of narrowly distributed macro-moths were described as new species. Interestingly, both Arctesthes titanica and Arctesthes avatar were named after mythological deities and top-grossing blockbusters by famous filmmaker James Cameron: Titanic and Avatar, respectively.

Each of the newly described species are believed to be restricted to only a couple of subalpine/alpine localities. Therefore, they are particularly vulnerable to extinction and need to be “considered of very high priority for conservation”, point out New Zealand scientists Brian Patrick (Wildland Consultants Ltd), Hamish Patrick (Lincoln University) and Dr Robert Hoare (Manaaki Whenua-Landcare Research) in their paper in the open-access journal Alpine Entomology.

Because of its relatively large size, one of the new discoveries: A. titanica, was named in reference to the Titans: the elderly gods in Greek mythology and the legendary, if ill-fated, record-breaking passenger ship ‘Titanic’, which became the subject of the famous 1997 American epic romance and disaster film of the same name. Unfortunately, the moth’s small wetland habitat is located in an area that is currently facing a range of damaging farming practices, such as over-sowing, grazing, stock trampling and vehicle damage.

On the other hand, A. avatar received its name after Forest & Bird, the New Zealand conservation organisation that was behind the 2012 BioBlitz at which the new species was collected, ran a public competition where “the avatar moth” turned up as the winning entry. The reference is to the indigenous people and fauna in Avatar. Just like them, the newly described moth is especially vulnerable to habitat change and destruction. In addition, the study’s authors note that the original avatars came from Hindu mythology, where they are the incarnations of deities, including Vishnu, for example, who would transform into Varaha the boar.

In conclusion, the scientists point out that future studies to monitor and further understand the fauna of New Zealand are of crucial importance for its preservation:

“Quantitative studies as well as work on life histories and ecology are particularly needed. Already one formerly common endemic geometrid species, Xanthorhoe bulbulata, has declined drastically and is feared possibly extinct: its life history and host-plant have never been discovered. Without further intensive study of the fauna of modified and threatened New Zealand environments, we will be unable to prevent other species slipping away.”

Human impact on the activities and social behaviour of urban capuchin monkeys

To better understand how primates modify their behaviour to adapt to the increasing presence of humans, a research team monitored 17 robust capuchin monkeys for a year and a half.

Confined to a small green area, surrounded by houses and small corn and soy plantations in the municipality of Foz do Iguaçu (Brazil), the primates were frequented by both city government officers and casual visitors. It was found that the monkeys spent more time roaming around in search for food, but less in feeding, resting and socialising. This is considered to be the result of a diet comprising predominantly of human-provided food and restriction of dispersal due to a fragmented habitat.

The study, conducted by the Brazilian team of Janaína Back and Dr Lucas Aguiar, both affiliated with the Federal University for Latin American Integration and Adriane Suzin of the Federal University of Uberlândia, is published in the open-access journal Zoologia.

Capuchin monkeys are omnivorous primates with flexible social and feeding behaviour inhabiting Central and South America. Living in multi-male, multi-female groups of 3 to 30 individuals, they are heavily dependent on their social interactions, both agonistic and affiliative (grooming, social play, alloparental carrying etc.) However, they allocate their time according to many factors, including season, daytime, social status, sex and age. Their pronounced adaptability is also seen in their behavioural repertoire, which can rapidly increase in response to new stimuli in the environment.

In late 2011, the researchers began their study by spending three months familiarising the monkeys to the presence of human observers. Then, they conducted regular visits between January 2012 and June 2013, when they would monitor the population for a total of 10 hours a day. Thus, they obtained 15,208 behavioural records and noted 2,538 events of social interaction.

While the monkeys were seen to feed on the fruits of the native and exotic trees present in the habitat, as well as food provided by the city government officers and the passers-by, according to the data, their diet comprised 71% human-provided food, mostly given by casual visitors. The monkeys seemed to have accepted the scattered and unpredictable nature of their primary source, resulting in more time spent in searching for food (80%), when compared to populations in larger fragments and continuous forest. It could also be that the animals were spending extra time travelling to explore the many objects left behind by people.

Naturally, more time spent in searching for food results in less time left for social interactions. Additionally, roaming animals are staying apart from each other for longer periods of time.

On the other hand, the monkeys were reported to spend less time eating, which is considered to be a consequence of the human-provided food being much higher in energy content and availability, thus satisfying individual demands with less effort and smaller amounts.

To the surprise of the researchers, the capuchins were not found to spend more time resting, which is a commonly observed phenomenon in animals regularly fed by humans. The team attributes the deviation to pedestrians frequently disturbing the monkeys by using the forest patch as shortcuts.

As a result of food abundance, the monkeys were rarely seen to act in a hostile manner with each other. Alternatively, it could be that the population favours affiliative and cooperative social interactions since the fragmented habitat had led to well-pronounced kinship in the group.

“In conclusion, we found deviations in activity budget and social interactions of capuchins living in the studied small urban fragment, possibly influenced by the availability of anthropic food and the restrictions for dispersion imposed by the urban matrix,” say the scientists.

“These kind of studies are very important in Primate Conservation Biology, because we have an urgent demand to understand how primates adapt around human beings, as the contact between human and nonhuman primates are an inescapable aspect today.”

Austrian Herpetological Society’s journal Herpetozoa moves to Pensoft’s ARPHA platform

Newly published research articles demonstrate numerous innovative features to the benefit of readers, authors and all other users

Published since 1988 by the Austrian Herpetological Society (ÖGH, Österreichische Gesellschaft für Herpetologie), the renowned peer-reviewed, open-access Herpetozoa is added to the growing portfolio of international scientific journals published on the ARPHA scholarly platform, as a result of a new partnership with scholarly publisher and technology provider Pensoft.

Follow Herpetozoa on Twitter and Facebook.

As before, Herpetozoa welcomes original research articles, short contributions and reviews covering all aspects of the study of amphibians and reptiles. The papers are published in English, whereas a translation of the abstract into German may also be included. The journal operates a single-blind peer review policy.

Thanks to the fast-track and convenient publishing provided by ARPHA, 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.

Right underneath the new sleek look and feel welcoming users from the journal’s homepage, there are a lot of high-tech perks to benefit authors, readers, reviewers and editors alike.

Furthermore, all publications are available in three formats (PDF, XML, HTML), complete with a whole set of semantic enhancements, so that the articles are easy to find, access and harvest by both humans and machines.


Editor-in-Chief of Herpetozoa, Dr Günter Gollmann states:

“We decided to move to Open Access online publishing to increase the visibility of our journal, and to speed up the publication process. The highly attractive presentation provided by Pensoft should boost attention for the papers we publish. While Herpetozoa welcomes contributions of any length on all topics in herpetology, I hope that authors will appreciate the suitability of the new format for data-rich studies in natural history. Such research is often dismissed as “too descriptive” by other international journals, but is essential for conservation of biodiversity.”

ARPHA’s and Pensoft’s founder and CEO Prof Lyubomir Penev says:

“I am pleased to see Herpetozoa having found its new home on the ARPHA platform amongst all Pensoft journals and other highly reputed academic titles from around the globe. With our own strong background in zoological sciences, I am certain that our partnership with Herpetozoa will be quick to prove fruitful to both of us, but most importantly, to all readers, authors, editors and reviewers alike.”

With its move to the open-access, technologically advanced scholarly publishing platform, Herpetozoa lines up next to historical and well-known society journals, including Deutsche Entomologische Zeitschrift, Alpine Entomology (previously Journal of the Swiss Entomological Society), Journal of Hymenoptera Research, Zoologia and others, which have all chosen to modernise with the help of ARPHA.

What’s new on Herpetozoa?

Amongst the first batch of articles published in Herpetozoa in partnership with ARPHA/Pensoft, there is an Italian study tracking the long-disputed origin of the Mediterranean-native common chameleon (Chamaeleo chamaeleo) back to its ancestors in North Africa and the Middle East. Another paper by a research team from Romania compares the effects of carnivore, vegetarian and omnivorous diets on the growth, development and mortality in tadpoles of the common toad. In their study of the South American frog species Leptodactylus fuscus, scientists from Universidade Federal de Mato Grosso do Sul (Brazil) compare the diet of a population living in the wild with another one, which inhabits an urban environment. Their aim was to determine the impact urbanisation could be having on this otherwise abundant amphibian.

Following a series of recent surveys in north-western Liberia and south-eastern Guinea, an international team of researchers found three stiletto snakes which were later identified as a species previously unknown to science.

The discovery, published in the open-access journal Zoosystematics and Evolution by the team of Dr Mark-Oliver Roedel from the Natural History Museum, Berlin, provides further evidence for the status of the western part of the Upper Guinea forest zone as a center of rich and endemic biodiversity.

Curiously, stiletto snakes have unusual skulls and venom delivery system, allowing them to attack and stab sideways with a fang sticking out of the corner of their mouths. While most of these burrowing snakes are not venomous enough to kill a human – even though some are able to inflict serious tissue necrosis – this behaviour makes them impossible to handle using the standard approach of holding them with fingers behind the head. In fact, they can even stab with their mouths closed.

The new species, called Atractaspis branchi or Branch’s Stiletto Snake, was named to honor to the recently deceased South African herpetologist Prof. William Roy (Bill) Branch, a world leading expert on African reptiles.

The new species lives in primary rainforest and rainforest edges in the western part of the Upper Guinea forests. Branch’s Stiletto Snake is most likely endemic to this area, a threatened biogeographic region already known for its unique and diverse fauna.

The first specimen of the new species was collected at night from a steep bank of a small rocky creek in a lowland evergreen rainforest in Liberia. Upon picking it up, the snake tried to hide its head under body loops, bending it at an almost right angle, so that its fangs were partly visible on the sides. Then, it repeatedly stroke. It is also reported to have jumped distances almost as long as its entire body. The other two specimens used for the description of the species were collected from banana, manioc and coffee plantations in south-eastern Guinea, about 27 km apart.

“The discovery of a new and presumably endemic species of fossorial snake from the western Upper Guinea forests thus is not very surprising,” conclude the researchers. “However, further surveys are needed to resolve the range of the new snake species, and to gather more information about its ecological needs and biological properties.”
