Heat-loving Australian ants believe in diversity, hint 74 species new to science

The ‘furnace ants’ or ‘honeypot ants’ present a very large genus of ants, Melophorus, confined to Australia. Long believed to be megadiverse, some scientists have even suggested that the group may contain ‘well over 1000 species’. However, to this point, only 32 species and subspecies had been described.

Scientists Dr Brian Heterick of Curtin University, Dr Mark Castalanelli of Ecodiagnostics Pty Ltd and Dr Steve Shattuck of the Australian National University, funded by an internationally competitive Australian Biological Resources (ABRS) grant, set out to find the true facts.

As a result, they discovered as many as 74 new species belonging to Melophorus. In their study, published in the open access journal ZooKeys, they also provide a taxonomic key to the workers of a total of 93 species in the genus.

Among the studied ants, there are quite bizarre ones, including a species (Melophorus hirsutus) whose eyes are strangely protruding out of his head to a varying degree. In the extreme cases, the eyes are so pointy that could be likened to ice-cream cones. Named many years ago, this ant appears to be older than the rest of the examined living species. Furthermore, unlike most of them, it does not seem adapted to heat. It is confined to the wet eastern coast of Australia.

Dr Heterick spent two weeks collecting specimens in the often rugged and forbidding terrain of Western Australia, while the team also asked a number of major museum collections to loan them specimens.

The newly collected ants were placed in alcohol and subjected to genetic tests using one mitochondrial and four nuclear genes. The findings were then compared with those from physical examinations to prepare the taxonomic key – a set of distinctive features per species that can be used to differentiate within the group.

Given the generally complex nature of these ants, the authors expect for the genus to further expand in future. They speculate that even though the numbers may increase to around 100 species, not the ‘well over 1000’ previously predicted, they still illustrate an incredible diversity.

The authors estimate that Melophorus arose around 35 million years ago. The closest relatives of the genus are also confined to the Australasian region with the exception of a single genus living in South America.

Furthermore, the genus is also quite astonishing thanks to another trait shared among the species.

“By the way, this group of ants has a thing or two to tell those of us who get lost easily!” comments lead author Dr Brian Heterick.

“They can find their way home in a featureless landscape by means of an internal compass influenced by information gathered on earlier journeys. We are not the first species to use a computing system!”

An overlooked and rare new gall-inducing micromoth from Brazil

A new species and genus (Cecidonius pampeanus) of primitive monotrysian micromoth from the Brazilian Pampa biome has been recently discovered to induce scarcely noticeable galls under the swollen stems of the Uruguayan pepper tree.

Gall-inducing moths lay their eggs in the tree bark, where the larvae form the characteristic roundish swellings as they grow larger. In their turn, these galls attract various parasitoids and inquiline wasps – wasps that have lost the ability to form galls for their own eggs – and so they take advantage of the galls of other species, while under development. The inquilines modify the galls into larger ones which subsequently last longer and attract even more attention. As a result, even though abundant as young, the new moth’s larvae rarely survive and their density in the field later in life is low.

While free-living gall moths are generally rare, the studied genus pupates on the ground, resulting in its being overlooked for over a century. Furthermore, the galls fall to the ground where the last instar larvae undergo a period of suspended development for months. They stay motionless within their gall until pupation and emerge as adults in the next growing season.

After all this time, this species has finally been recognised in the open access journal ZooKeys by an international research team, led by Dr. Gilson Moreira, Universidade Federal do Rio Grande do Sul, Brazil. In their paper, the scientists describe the gall, immature stages and adults of the moth. They also provide information on its natural history in conjunction with one of the associated parasitoid and inquiline wasps.

“It took several years to obtain a small number of C. pampeanus pupae and adults to use for the description,” say the authors.

“The existence of these galls has been known for more than a century. However, biologists believed they are induced by the inquiline wasps,” they explain. “Consequently, it turned out that the wasps do not induce galls, but rather modify them early in development into large and colourful, visually appealing galls.”

The study also provides strong evidence that the species is under threat of extinction and the scientists suggest that protective measures need to be taken to conserve it.

In fact, they found strikingly low levels of gene flow amongst populations of C. pampeanus. In their paper, the team also emphasises that, in case of extinction of the primary gall inducer, a whole insect community associated with their galls will follow. This could happen even before science becomes familiar with all of these species.

Open savannahs of southern Brazil, where populations of the new moth’s host plant (the Uruguayan pepper tree) are found, have been suffering from anthropic impact for decades, mostly caused by agriculture and cattle ranching.

Curiously, the present study is the first in Brazil to suggest that a micromoth and its associated fauna should be subjected to conservation measures.

Extant populations of the new species are distant and isolated from each other, being restricted to a small geographic area in the northeast Southern Brazilian “Campos” (= Pampean savannah), a neglected biome from a nature preservation perspective. Most of the moths have retreated to higher elevations, such as hilltops and hill slopes interspersed with small bushes, where they get shelter from the anthropic influence.

3D avatars for three new rare ant species from Africa including the Obama ant

Three new, rare ant species recently discovered in Africa were named after important figures for the African biodiversity conservation – the former United States president Barack Obama, the Nigerian writer and environmental activist Ken Saro-Wiwa, and the world-renowned biologist Edward O. Wilson.

The scientists from the Okinawa Institute of Science and Technology Graduate University (OIST), who had their discovery published in the open access journal ZooKeys, used a new, revolutionary method to compile scans of the ants and create 3D avatars allowing for a unique and detailed visualisation of the insects’ insides.

https://skfb.ly/6sPvr

Curiously, the Obama ant, Zasphinctus obamai, was collected from the Kakamega Forest National Park, Kenya, located near Barack Obama’s ancestral family village. The 44th President of the United States of America is famous for his numerous initiatives towards the conservation of fragile natural habitats around the globe.

Ken Saro-Wiwa, who also has his name perpetualised in the new ant species Zasphinctus sarowiwai, was a Nigerian writer and environmental activist who, after campaigning against irresponsible oil development, was executed in 1995.

“By naming a species from threatened rainforest habitats after him, we want to acknowledge his environmental legacy and draw attention to the often-problematic conservation situation in most Afrotropical rainforests,” explain the biologists in their paper.

The third new species, Zasphinctus wilsoni, bares the name of the biologist Edward O. Wilson, whose foundation has contributed greatly to the resurrection of the Gorongosa National Park in Mozambique.

The 3D avatars were created with the help of X-ray microtomography, or micro-CT, which is a technology similar to the one used in hospitals for CT scans, but relying on much higher resolution. The three-dimensional reconstructions made it possible for the scientists to look into details as tiny as the ants’ mouthparts and even their legs and hairs. Moreover, this method does not require damaging the rare specimens.

“We saw things that nobody ever looked at,” says Dr. Hita Garcia, first author on the study and a member of the Biodiversity and Biocomplexity Unit at OIST.

While closely related ants had already been known as predators of other ant species, the scientists needed to study the data provided by the scans to confirm that the new species are top predators as well.

“Normally when you describe a new species, you don’t know much about its biology,” further explains Dr. Hita Garcia, “but with the 3D reconstructions researchers can discover details right away.”

To the biologists, these reconstructions hint at a future of virtual taxonomy with the potential to alleviate issues of time, money, and specimen damage.

Furthermore, the 3D models also allow for the data to be easily accessible from anywhere. To show this, the scientists have uploaded the reconstructions to the open access Dryad Digital Repository.

“If someone wants to see the Obama ant, they can download it, look at it, and 3D print it,” Dr. Hita Garcia points out.

“Since these ants are from very threatened habitats in Africa, we wanted to pick names that draw attention to the environment, and not just the ants,” he concludes. “The rainforests in equatorial Africa, as well as the savannah in Mozambique, needs to be protected before the habitats and animals living within them are destroyed.”

New species of crab with unusual outgrowths has its name written in the stars

A new species of crab with star-shaped tubercles all over its body has been collected from red coral beds during a survey at a small seamount by Peng-Chia-Yu Island, Taiwan. It has also been found in the Philippines. It is described in the open access journal ZooKeys.

This astonishing creature is distinct with its carapace and chelipeds covered in pointy protrusions. Interestingly, these change with age, becoming shorter, blunter and mushroom-shaped to resemble wart-like outgrowths and granules. Regardless of their sex, as the crabs grow larger, their carapaces also get proportionately rounder and wider.

The curious protuberances on the bodies reminded the research team of Dr. Peter Ng, National University of Singapore, and Dr. Ming-Shiou Jeng, Biodiversity Research Center, Academia Sinica, Taiwan, of stars. Hence, the crab was given the name Pariphiculus stellatus, where stellatus translates as ‘starry’ from Latin.

The colouration of P. stellatus varies among specimens. While predominantly orange with white patches, their shade could be either dull, pale or intense. The white spots might cover some of the protrusions or extend over most of the body. The underside of the body is dirty white to light brown.

Another rare crab species, Acanthodromia margarita, has been reported for the first time from Taiwan in the same study, having previously been known from the Andaman Sea in the eastern Indian Ocean, Japan and the Philippines. The collected female specimen is one of the largest representatives of the species known so far.

“With their bright orange to pink bodies, these hedgehog-like crabs are truly striking in life!” says Dr. Peter Ng.

The Western Ghats of India revealed two new primitive species of earthworm

The Western Ghats mountains lie at the southwestern continental margin of Peninsular India and extend all the way from Gujarat to Kerala. The massif has earned its place amongst the eight ‘hottest’ biodiversity hotspots in the world.

There is a great variety of vegetation types which, coupled with the high rainfall and the moderate yearly temperature in the Western Ghats, provide many different habitats. Therefore, the mountains an area rich in earthworm, as well as amphibian and reptile diversity.

The two new species, named Drawida polydiverticulata and Drawida thomasi, have been discovered in the Western Ghats mountain ranges in Kerala by scientists Dr. S. Prasanth Narayanan, Mr. S. Sathrumithra, Dr. G. Christopher, all affiliated with Mahatma Gandhi University and Dr. J.M. Julka of the Shoolini University, India. They belong to the primitive family Moniligastridae. The species are described in the open access journal ZooKeys.

The new earthworms are distinguished by a set of characters. For one of them – Drawida polydiverticulata – there were peculiar features which determined its species name (polydiverticulata). It turned out that its multiple lobes, also called diverticulums, an organ located in the front of its body, are unique amongst the members of the genus. This species was found to be widespread in the protected shola grasslands of the Munnar region, including Eravikulam National Park, Pampadun Shola National Park and Chinnar Wildlife Sanctuary.

The second new earthworm, Drawida thomasi, was collected at the Kozhippara Waterfalls near Kakkadampoyil, at the border between Malappuram and Kozhikode. The species name (thomasi) is a tribute to Prof. (Dr.) A.P. Thomas, the Director of the Advanced Centre of Environmental Studies and Sustainable Development (ACESSD), Mahatma Gandhi University, “who initiated the taxonomical studies on the earthworms in Kerala after being at a standstill for almost a century.”

In addition to the new species, the scientists also report the occurrence of five species of the same genus that have not previously been recorded from the state.

To date, there are 73 species of the genus Drawida confirmed to be living in the Indian subcontinent. However, the greatest concentration (43 species) is found in the Western Ghats. The genus has an important centre of speciation in the southernmost state of Kerala.

Prior to this study, there had been sixteen Drawida species known from the state with ten of them being unique. The present discovery of two new species and five new local records further contributes to the vast species richness of the genus in the state.

At present, there are about 200 species known in the genus Drawida. Their habitats are spread across India throughout the Indochina region to southeastern Asia and up to the north in Japan.

New proposal for a subspecies definition triggered by a new longhorn beetle subspecies

The discovery of a new subspecies of longhorn beetle from Scandinavia triggered a discussion on the vague organism classification rank ‘subspecies’.

As a result, a newly proposed definition of subspecies has been published along with the description of the taxon in the open access journal ZooKeys by the research team of Henrik Wallin and Johannes Bergsten from the Swedish Museum of Natural History and Torstein Kvamme from the Norwegian Institute of Bioeconomy Research.

The northernmost populations of Saperda populnea display a number of divergent traits, including a shorter male antenna and reduced pubescens. In contrast with their most closely related subspecies (Saperda populnea populnea), whose favourite host plant, amongst others, is the European aspen, the new subspecies (Saperda populnea lapponica) specialised exclusively on downy willow (Salix lapponum).

According to the once no less disputed definition of species, regardless of their unique traits, populations cannot be considered as separate species until they are no longer able to produce fertile offspring according to the Biological Species concept, this being one of a number of proposed species concepts. A consensus is emerging around the unified species concept defining species as separately evolving (meta) population lineages.

However, differentiating between subspecies nowadays is a significantly tougher task, since there is no stable definition of the rank yet. Through the years, there have been various explanations of what a subspecies is and what criteria it needs to meet in order to be classified as one.

Compared to previous definitions, the researchers decode it quite simply. To them, the only necessary attributes a population needs to possess before being deemed a subspecies are that they are a potentially incipient new species; diagnosed by at least one heritable trait; and either partially or completely isolated geographically.

Furthermore, they refute a number of factors, including reciprocal monophyly in neutral markers, the “75% rule”, reproductive compatibility and the degree of gene flow.

The concept of subspecies has been so problematic that there have been even those scientists who have argued that taxonomy needs to discard it altogether.

However, the authors note that it is already formally recognised by the International Commission on Zoological Nomenclature (ICZN 1999), “albeit without giving any advice or criteria for its recognition.”

“The concept is more than a mere academic debate as subspecies are recognized in various Red Lists and conservation programs, and hence the recognition as a subspecies or not can have legal and monetary consequences.”

Two new beetle genera and 4 new species from the Australopacific in a new monograph

An outstanding monograph of the Australopacific Region’s saprinine hister beetles supported by the Alexander von Humboldt Foundation

Amid his ongoing revisionary work on a number of hister beetle genera, the Slovakian-born naturalised Dutch entomologist and Alexander von Humboldt Foundation researcher, Dr. Tomáš Lackner, Bavarian State Collection of Zoology, together with fellow entomologist Dr. Richard Leschen, Landcare Research, discovered two new genera and a total of four new species from the Australopacific Region. The newly described endemic insects are featured in an extensive monograph published in the open access journal ZooKeys.

Hister beetles, also known as Clown beetles because of their flattened legs, represent a quite diverse family (Histeridae) of beetles living almost everywhere around the world. Amongst their characteristic traits are their shiny metallic wings. Most of these beetles are predaceous and feed on larvae of other insects, including some pests. Occasionally, some species filter-feed on dung. Curiously, the Clown beetles tend to play dead when threatened.

While the hister beetle subfamily Saprininae is common and diverse throughout the globe, with only 40 species in nine native and three introduced genera, they are poorly represented in the Australopacific Region. This is one of the reasons the present discoveries documenting the new diversity in the group are remarkable.

The authors note that their scarcity in the area might be as a result of the long-standing isolation of the Australian continent in combination with the originally densely forested large islands like New Zealand and New Guinea.

However, “the Australopacific Region harbors several species with very interesting morphologies and ecologies,” point out the scientists.

Amongst the most impressive newly described saprinines, there is the first truly myrmecophilous species and genus (Iridoprinus myrmecophilus) known from the region, which is likely to be dependent on its co-habitation with ants. The beetle is only known from Australia where it has been collected from the nests of another species, endemic to the country – the Meat anSimilarly, the new histerid species Saprinus rarus is the first known termitophilous saprinine from the Australopacific Region and only the third in the subfamily as a whole. Found in the nest of the arboreal Tree termite, the species had been previously collected, but it has been so rare that it has not been determined as a new to science species until now. Hence, it earned the scientific name rarus as in ‘rare’.

In conclusion, the team noted the next challenge about the Australopacific saprinines – the genus Saprinodes which is not only restricted to Australia, but also has a life history shrouded in mystery. So far, it has only been collected from pitfalls and flight intercept traps.

For lead author Dr. Tomáš Lackner, this is the tenth in a line of studies focused on the world’s remarkable histerids published in ZooKeys.

Four new fruit fly species from the Himalaya and information about their flower visitation

The first record of flower visitation in a group of fruit flies from Himalayan India and a total of four new species are described in the open access journal ZooKeys. In their paper, scientists also revise the descriptions of all representatives of this genus (Lordiphosa) in India.

Following a number of observations in Nainital and Darjeeling, India, the team of Dr Rajendra S. Fartyal and Pradeep C. Sati, both affiliated with HNB Garhwal University, Sushmika Pradhan, and Rabindra N. Chatterjee of University of Calcutta, Prof. M.J. Toda of Hokkaido University, and Mukul C. Kandpal and Birendra K. Singh of Kumaon University conclude that two of the new species visit the flowers of spiked ginger lily and angel’s trumpet.

The distributional range of the genus stretches from the tropics of the Oriental to the subarctic of the Palearctic region, with the highest species richness in the subtropics of the Orient. However, these fruit flies have been thought to be poorly represented in India with only seven species recorded so far.

Until now, the fruit flies in the genus Lordiphosa have been known to breed on herbaceous plants. Their larvae are either leaf miners, or feed on decayed leaves and stems.

The specimens used in the present study have been collected from four different hill stations in the Himalayan region in India. These localities are covered with dense mixed-deciduous subtropical forests. They are characterised with extremely moist conditions due to the heavy rainfall during the summer monsoon season.

The authors note that one of the revised species, named L. neokurokawai, has an extraordinary type of sex comb — a male-specific morphological feature composed of thick comb-like structures and located on the foreleg. This adaptation is only seen in two fruit fly genera. It is used in a variety of ways in tactile interactions between males and females during both courtship and mating.

The scientists point out that this finding is important when considering the evolution of the sex comb in the genus Lordiphosa. It is suggested that the sex comb has once evolved in an ancestor of the genus, and proceeded to rapidly diversify through sexual selection. However, “this hypothesis requires further investigation,” the authors say.

Behind Green Eyes: New species of deep-water hermit crab finds itself unusual shelters

‘Green-eyed hermit crab’ is the common name for a new species recently discovered off the West Coast of South Africa. Apart from its magnetic stare, however, there is a number of characteristic morphological traits and an unusual home preference that all make the crustacean unique.

Formally named after the University of Cape Town (UCT) alumnus Dr Lara Atkinson, the new hermit crab Paragiopagurus atkinsonaeis described by PhD candidate Jannes Landschoff, UCT, and Dr Rafael Lemaitre, Smithsonian Institution, USA, in the open access journal ZooKeys.

The Green-eyed hermit crab measures merely 70 mm in length and sports a coloration of mottled orange nuanced with cream to white. Among its distinct traits is the significant sexual dimorphism, where the males grow much larger right chelipeds in comparison to females.

Much like other hermit crabs in its family (Parapaguridae), the little crustacean does not use the shells of other molluscs to shelter its vulnerable body, but rather finds a home in the soft, polypy masses built from sand and material created by sea anemones which go on to live on the backs of these crabs in an amazing symbiosis.

“So, when you hold it [the hermit crab], it’s just organic material glued together with some sand,” explains Jannes in the UCT’s announcement about their discovery.

“Even more curiously, parapagurids start off in the usual way, occupying a tiny gastropod shell. But these eventually become deposited within this non-calcified ‘amalgam’ created by the anemones. As the hermit crab grows, its live ‘shell’, or carcinoecia, grows with it.”

The new species was discovered during a three-week survey back in 2013, conducted by the Department of Forestry and Fisheries and the South African Environmental Observation Network in the shallower deep waters (199 m to 277 m) off the West Coast of South Africa. Lara was on board one of the vessels when an unusual green-eyed crab turned up among the numerous specimens collected in one of the trawls. It was at that moment that she noticed that there was something peculiar about it and sent it for identification.

Restricted to a surprisingly small area for no obvious reason, the new species might be just bringing up some very important conservation messages.

“The area isn’t noticeably biologically or oceanographically distinct, but more detailed sampling from the area will tell us more about the habitat conditions. Future studies need to take this into account and give the area more research attention. If there’s something unusual about the site, you’d want to be careful, especially with mining operations along the West Coast,” says Jannes.

“Incidents like these are flags for future protection. The bottom line is we know so little about these offshore habitats from an ecological point of view. And if you’re planning for a marine protected area, you have to know what it is you’re protecting in that area.”

The ‘Star dust’ wasp is a new extinct species named after David Bowie’s alter ego

During her study on fossil insects of the order Hymenoptera at China’s Capitol Normal University, student Longfeng Li visited the Smithsonian National Museum of Natural History, Washington, carrying two unidentified wasp specimens that were exceptionally well-preserved in Burmese amber. This type of fossilized tree resin is known for the quality of the fossil specimens which can be preserved inside it. Being 100 million years old, they provide an incredible view into the past.

The subsequent analysis of the specimens revealed that both represent species new to science. Furthermore, one of the wasps showed such amazing similarities to a modern group of wasps that it was placed in a currently existing genus, Archaeoteleiawhich has long been considered as an ancient lineage. The species are described in a study published in the open access Journal of Hymenoptera Research.

However, Archaeoteleia has changed since the times when the ancient wasp got stuck on fresh tree resin. The authors note that “a novice might not recognize the characters that unite the fossil with extant species”. For instance, the modern wasp species of the genus show visibly longer antennal segments and a different number of teeth on the mandible when compared to the fossil. In turn, the description of the new extinct species enhances the knowledge about living species by highlighting anatomical structures shared by all species within the genus.

This fossil wasp with living relatives received quite a curious name, Archaeoteleia astropulvis. The species name, astropulvis, translates from Latin to ‘star dust’. The discoverers chose the name to refer to both “the ancient source of the atoms that form our planet and its inhabitants”, as well as to commemorate the late David Bowie’s alter ego – Ziggy Stardust.

Unlike the Star dust wasp, the second new species belongs to a genus (Proteroscelio) known exclusively from Cretaceous fossils. Likewise, it is a tiny insect, measuring less than 2mm in length. It also plays an important role in taxonomy by expanding the anatomical diversity known from this extinct genus.

The authors conclude that their discovery, especially the Star dust wasp and its placement in an extant genus, where it is the only fossil species, “exemplifies the importance of understanding the extant fauna of a taxon to interpret fossils”.

“Such union of fossil and extant morphologies is especially illuminating and requires examination of both kinds of specimens,” they add.
