Moth gift: Winner of an eBay auction thanks his mother by naming a new species after her

The loving son presented the name to his mother on St. Valentine’s Day

Winner of an eBay auction Steve Mix received the opportunity to pick the name for a new species of satiny-white winged moth collected from the white gypsum dunes of the White Sands National Monument, New Mexico. A fan of butterflies and moths himself, he chose to honor his supportive and encouraging mother Delinda Mix, so the moth is now formally listed under the species name delindae. It is described in the open access journal ZooKeys.

Having spent 10 years studying the moth fauna at the White Sands National Monument, Eric H. Metzler, curator at the Michigan State University, but also research collaborator at the National Museum of Natural History, Smithsonian Institution, and research associate at the University of New Mexico and the University of Florida, discovered the moth during the first year of the study, in 2007. Back then, he spotted a curious small white moth with a satiny appearance, which immediately drew his attention.

Already assigned to the genus Givira to the family commonly known as carpenter millers, the moth was yet to be identified as a species. While most of its North American ‘relatives’ are either dark-colored, or have substantial dark smudges on the forewings, there are only four of them, including the new species, which are substantially white with few or no dark markings.

Further hindrance occurred when the researcher tried to study the specimens, as pinned moths turned out greased due to their abdomens being full of fatty tissue. However, the specialist managed to degrease them by carefully brushing their scales, and, having compared them to related species, confirmed them as representatives of a species new to science.

Then, Eric joined the fundraising event, organized by the Western National Parks Association (WNPA), a non-profit education partner of the US National Park Service. The highest bidder in the eBay auction would receive the chance to pick the scientific name for the satiny-looking moth, and thus, become part of history. Having won the opportunity, Steve Mix, who himself had once been interested in studying butterflies and moths, and has been maintaining his fondness of them ever since, decided to name the species after his mother Delinda Mix, in gratitude for “the support and encouragement she gave to her son”.

“Steve Mix submitted the winning bid, and he chose to have the moth named after his mother because of the lasting nature of this naming opportunity”, shares Eric. “I received no remuneration in this fundraising venture, and by volunteering my personal money, time, expertise, and experience I was able to help WNPA gain world-wide positive publicity while raising some much needed cash. The rewards to me were being able to help WNPA and Steve Mix honor his mother, which is just so very sentimental”.

“WNPA is so pleased that we were able to work with Eric and we are grateful to Steve. This project is a shining example of working together towards the common good of our parks with the added value of providing a priceless experience for everyone involved”, says Amy Reichgott, Development Manager at the Western National Parks Association.

New moth in Europe: A southern hemisphere species now resident in Portugal

As travelling in the 21st century is easier than ever, so is for species to make their way to new areas, sometimes increasing their distributional range, or even establishing whole new habitats. On the other hand, when they leave their natural predators and competitors behind, and find abundance of suitable resources somewhere else, they are running the risk of becoming invasive.

Nevertheless, such is not the case of a small, darkish brown moth from the southern hemisphere that is now resident in central Portugal. There, the species do not exhibit invasive behaviour, and so far has been only observed in very low numbers. The discovery is published in the open access journal Nota Lepidopterologica by an international research team, led by Martin Corley, CIBIO-InBIO, Portugal.

In 2012, Jorge Rosete, one of the co-authors of the study, spotted a female specimen that he could not identify near his house. When Martin took a look at it, he placed it in the concealer moth family (Oecophoridae), but was unable to recognise neither its species, nor its genus. It did not took long before a few more specimens were found, including males.

Initially, Martin thought the moth might originate from Australia, given the abundance of eucalyptus plantations in the area where it was found, and the fact that there are more concealer moth species in Australia than on any other continent. However, despite their efforts and contacts with other researchers, they failed to find an Australian species to match the Portuguese specimens. As a result, the mystery remained for the next four years, until a molecular study into moth DNA pulled the curtains.

A fragment of DNA, also called DNA barcode, matched three other genetically identical unnamed specimens, originally collected from South Africa, in the DNA database BOLD. Further collaboration with Alexander Lvovsky, Russian Academy of Sciences, allowed the assignation of the specimens to a species name: Borkhausenia intumescens, known from South Africa. However, it did not end there. Further research into museum collections showed that in fact this species had been previously described from Argentina as Borkhausenia crimnodes, and therefore should be named as such.

The origin of the Portuguese specimens remain a mystery, but it is evident that the species is now established in central Portugal. The larvae of other species in the same genus feed on decomposed plants, so this is likely the case with the moth species as well. It might be that it has entered the country through Figueira da Foz port along with imported timber from South America intended for the paper industry.

It is not known if this is a South African species that had first been transported to South America, and then – to Portugal, or if it is originally South American. It is also possible that it is not native in neither of these areas, and instead originates from another country, where it has not even been discovered yet. The moth favours warm temperate zones and potentially might appear anywhere in the world with suitable climate.

New species of moth named in honor of Donald Trump ahead of his swearing-in as president

Days before Donald J. Trump steps forward on the Inaugural platform in Washington to assume the role of the 45th President of the United States of America, evolutionary biologist and systematist Dr. Vazrick Nazari named a new species in his honour. The author, whose publication can be found in the open access journal ZooKeys, hopes that the fame around the new moth will successfully point to the critical need for further conservation efforts for fragile areas such as the habitat of the new species.

While going through material borrowed from the Bohart Museum of Entomology, University of California, Davis, Dr. Vazrick Nazari stumbled across a few specimens that did not match any previously known species. Following thorough analysis of these moths, as well as material from other institutions, the scientist confirmed he had discovered the second species of a genus of twirler moths.

While both species in the genus share a habitat, stretching across the states of California, USA, and Baja California, Mexico, one can easily tell them apart. The new moth, officially described as Neopalpa donaldtrumpi, stands out with yellowish-white scales present on the head in adults. In fact, it was in these scales that the author found an amusing reference to Mr. Trump’s hairstyle and turned it into an additional justification for its name.

Donald Trump’s flying namesake is announced only a month following the recently described species of basslet named after predecessor President Barack Obama, also published in ZooKeys. The fish is only known from coral reefs in the Papahānaumokuākea Marine National Monument, Northwestern Hawaii, a nature reserve which the 44th President of the United States of America expanded to become the largest protected marine area in the world.

Being a substantially urbanized and populated area, the habitat of N. donaldtrumpi is also under serious threat.

“The discovery of this distinct micro-moth in the densely populated and otherwise zoologically well-studied southern California underscores the importance of conservation of the fragile habitats that still contain undescribed and threatened species, and highlights the paucity of interest in species-level taxonomy of smaller faunal elements in North America,” says discoverer Dr. Vazrick Nazari. “By naming this species after the 45th President of the United States, I hope to bring some public attention to, and interest in, the importance of alpha-taxonomy in better understanding the neglected micro-fauna component of the North American biodiversity.”

A colorful yet little known snout moth genus from China with 5 new species

A group of beautiful snout moths from China was revised by three scientists from the Institute of Zoology at the Chinese Academy of Sciences.

In their study, recently published in the open access journal Zookeys, entomologists Dr. Mingqiang Wang, Dr. Fuqiang Chen and Prof. Chunsheng Wu describe five new species and two newly recorded for the country.

Despite being morphologically interesting, the snout moth genus Lista remains little known. Usually, its members have bright-coloured wings, often pink, orange, or yellow, which makes them strikingly different from the rest in their subfamily (Epipaschiinae). In fact, it is because of the beautiful coloration that these moths are sometimes favourably compared to butterflies. However, these moths are indifferentiable from one another on the outside.

As a result of the present study, there are now ten species of Lista snout moths known from China, with their world fauna amounting to thirteen. Mostly distributed in the south the East-Asian country, the genus likely originates from there.

35 years of work: More than 1000 leaf-mining pygmy moths classified & catalogued

The leaf-mining pygmy moths (family Nepticulidae) and the white eyecap moths (family Opostegidae) are among the smallest moths in the world with a wingspan of just a few millimetres. Their caterpillars make characteristic patterns in leaves: leaf mines. For the first time, the evolutionary relationships of the more than 1000 species have been analysed on the basis of DNA, resulting in a new classification.

Today, a team of scientists, led by Dr Erik J. van Nieukerken and Dr. Camiel Doorenweerd, Naturalis Biodiversity Center, Leiden, The Netherlands, published three inter-linked scientific publications in the journal Systematic Entomology and the open access journal ZooKeys, together with two online databases, providing a catalogue with the names of all species involved.

The evolutionary study, forming part of the PhD thesis of Doorenweerd, used DNA methods to show that the group is ancient and was already diverse in the early Cretaceous, ca. 100 million years ago, partly based on the occurrence of leaf mines in fossil leaves. The moths are all specialised on some species of flowering plants, also called angiosperms, and could therefore diversify when the angiosperms diversified and largely replaced ecologically other groups of plants in the Cretaceous. The study lead to the discovery of three new genera occurring in South and Central America, which are described in one of the two ZooKeys papers, stressing the peculiar character and vastly undescribed diversity of the Neotropic fauna.

Changing a classification requires a change in many species names, which prompted the authors to simultaneously publish a full catalogue of all 1072 valid species names that are known worldwide and the many synonymic names from the literature from the past 150 years.

Creating such a large and comprehensive overview became possible from the moths and leaf-mine collections of the world’s natural history museums, and culminates the past 35 years of research that van Nieukerken has spent on this group. However, a small, but not trivial, note in one of the publications indicates that we can expect at least another 1000 species of pygmy leafminer moths that are yet undiscovered.

Moth genitalia is the key to snout grass borers from the Western Hemisphere

Two scientists have produced an illustrated key to define the subtle differences between the 41 species of snout moth grass borers that currently dwell in the Western Hemisphere. The researchers conclude that the adults moths are too tough to tell apart by external characters, and therefore, the only way to identify the species is by dissecting and comparing genitalia. The study is published in the open-access journal ZooKeys.

This identification key is compiled by Dr. M. Alma Solis and Dr. Mark Metz. Both scientists are Research Entomologists at the Agriculture Research Service’s Systematic Entomology Laboratory, USDA. Dr. Solis is Curator of the U.S. National Pyraloidea Collection located at the National Museum of Natural History, Smithsonian Institution Washington, D.C.

The caterpillars of this group of snout moth grass borers feed on crops such as sugarcane, corn, rice, sorghum, and on native grasses throughout the Western Hemisphere, which makes many of the species quite harmful pests.

“The caterpillars of snout moth borers are economically important worldwide as pests of planted crops used for food or biofuel, so their identity is important for their control,” says Dr. Solis. “A key with images provides a simple way to identify adult moths, especially those that cannot be distinguished easily. A key to their identification is one of the most important results of taxonomic research.”

This research required locating ‘type specimens’ or original individuals that were used to describe the species in museums, borrowing them and preparing them for studies while avoiding inflicting any damage, so that they can be used by future researchers. These special specimens are the “standard bearer” for the scientific name and solidify the morphological as well as the molecular identity of a species.

Furthermore, Dr. Solis explained that it is not only important to be able to recognize if a species is new to science, as she and her colleagues recently discovered with a species feeding on Eastern gamagrass in the United States. It is also crucial for tying a species’ scientific name to its biology or genetic composition.

The biology of many moth species is still a mystery, but a recent study, where Dr. Solis participated, identified and studied the biology of some of the species. It showed that there may have been two introductions of the sugarcane borer moth species to southeastern United States and it is likely that there is a species which is currently ‘hidden’ under the same name. She concluded that there is still much left to discover about these moth species from the Western Hemisphere.

1,541 snout moth species and counting in the United States and Canada

The present snout moth list contains a ten-percent increase in the number of species since 1983. For the last thirty-three years snout moth specialists in the United States and Canada have been describing species new to science and recording species new to these two countries. Scientists have also published studies resulting in major changes to the classification above the species level, for example by studying snout moth “ears” (tympanal organs) and utilizing genes to study their relationships.

This check list was compiled over a three-year period by Dr. Brian Scholtens and Dr. M. Alma Solis. Brian Scholtens is a professor at the College of Charleston, South Carolina, and M. Alma Solis is a research entomologist at the Agriculture Research Service’s Systematic Entomology Laboratory, and curator of the U.S. National Pyraloidea Collection located at the Smithsonian Institution, National Museum of Natural History, Washington, D.C. Their results have been published in the open-access journal ZooKeys.

“A check list is one of the most important pieces of research, with many applications,” says Dr. Solis. “Knowing the fauna of a geographic area makes it possible to track species and, in this case, potential invasive species. The caterpillars of snout moths are economically important worldwide as pests of planted crops for food or biofuel, of forest trees, and of stored products such as wheat and nuts.”

“Many species, for example, the stored product pests, occur worldwide, but others, such as pest species of grasses including corn, can be restricted or only exist in certain geographic areas,” the scientist further explains. “It is important to be able to recognize as soon as possible that a particular species is not native to the United States or Canada.”

Scientists use Latin scientific names as “unique tags” to communicate about the morphological or molecular identity and habits of a species. One of the functions of taxonomists is to determine if a species is new or if it has already been described. Historically, confusion is created when the same species is described more than once (called a synonym) in other parts of the world.

A regional check list such as this one and a worldwide check list can work together to reinforce precision in the definition and communication about species, especially decreasing confusion about synonyms. Most worldwide check lists exist as online databases that can be updated. Dr. Solis said that they had cited new discoveries relevant to the North American snout moth fauna found in GLOBIZ, or the Global Information System on Pyraloidea, an electronic list of over 15,500 snout moth species names for which she is a collaborator.

Rare Amazonian butterfly named after British national treasure Sir David Attenborough

A beautiful new Black-eyed Satyr species has become the first butterfly named in honour of the popular naturalist and TV presenter Sir David Attenborough. Although not the first animal to be named after the British national treasure, the butterfly is so rare that it is known only from lowland tropical forests of the upper Amazon basin in Venezuela, Colombia, and Brazil. The study, conducted by an international team of researchers, led by Andrew F. E. Neild, Natural History Museum, London, and Shinichi Nakahara, McGuire Center for Lepidoptera and Biodiversity and Entomology & Nematology Department, University of Florida, is published in the open-access journal ZooKeys.

The presently described Attenborough’s Black-eyed Satyr, scientifically called Euptychia attenboroughi, has such a restricted distribution that all of its known sites lie within 500 kilometres from each other in the north-west of the upper Amazon basin.

Best known for scripting and presenting the BBC Natural History’s ‘Life’ series, Sir David Attenborough is also a multiple winner of the BAFTA award and a president of Butterfly Conservation.

“Other animals and plants have previously been dedicated to Sir David, but it makes us happy and proud to be the first to dedicate a butterfly species in his name,” says Andrew Neild. “Although we are a large team from several countries from across four continents and speaking different languages, we have all been deeply influenced and inspired by Sir David’s fascinating and informative documentaries.”

The butterfly’s atypical wings in comparison to its relatives, have been the reason the scientists took to plenty of diagnostic characters to define its taxonomic placement. The peculiar patterns and morphology initially led the researchers to think the species could be even a new genus.

“It was a surprise for us that DNA data supported inclusion of this new species in the existing genus Euptychia, since this species lacked a distinctive structural character which was considered to be shared by all members of the genus” explains Shinichi Nakahara.

Get to know them faster: Alternative time-efficient way to describe new moth species

Having collected thousands of moth and butterfly species from across Costa Rica, famous ecologist Daniel Janzen, University of Pennsylvania, and his team were yet to find out many of their names. When they sought help from Dr. Gunnar Brehm, the taxonomist realised he needed too much time to describe species in the framework of an extensive revision of the genus, especially as there are still only a few biologists skilled to do this.

In the end, he found a way to revise the Neotropical looper moth genus Hagnagorafast and efficiently through avoiding wordy descriptions, but focusing on diagnostic characters, illustrated external characters, genitalia structures and DNA barcoding instead. His study is available in the open-access journal ZooKeys.

Having been put together back in the 19th century, most of the species within the Neotropical moth genus Hagnagora had been described by 1913. In modern days, it seemed necessary for the taxon to be revised. As a result, Dr. Gunnar Brehm herein publishes a “concise revision” comprising twenty species. It includes two species that have been revived from synonymy, two subspecies reinstated to a species level, four species excluded from the genus and the description of three new to science. In honour of the people who had funded the research, the new species have been named after them.

Following the revision, the research concludes not only the DNA molecules divergence between the separate species, but some subtle differences such as size, form of the wing blotches or the shape of the male genitalia.

Curious characteristic behaviour traits have also been noted within the genus. The representatives of the discussed genus fold their wings vertically while resting just like most butterflies and unlike the majority of related geometrid moths. Similarly, three of the revised species were noticed to be active during the day when they would often perch on moist substances like rotting plants, mud or dung, from whose fluids they would find vital nutrients.

The author stresses on the fact that taxonomists can hardly keep up with the pace inventories are being compiled, nor with the accelerating destruction of tropical rainforests. “Taxonomists therefore need to accelerate their workflows and try to make their papers useful not only to other taxonomists but for ecologists who need their support”, Dr. Gunnar Brehm says.

“What used to be one species ten years ago, known as Hagnagora anicata, is now regarded as a complex of six species, and more might be discovered in South American rain forests”, Brehm says. “Integrating information of molecules and morphology, as concisely as possible, appears to be one promising way to cope with the problem of slow taxonomy”, he explains in conclusion.

Immaculate white: New moth species preferring dry habitats is a rare case for Florida

Spreading its wings over the sandhills and scrub of peninsular Florida, a moth species with immaculately white wings has remained unnoticed by science until Mr. Terhune Dickel brought it to the attention of Dr. James Hayden of the Florida Department of Agriculture and Consumer Services. As a result of their research, published in the open-access journal ZooKeys, the authors have also included a key to facilitate the recognition of different pale-winged moths and their close relatives.

With its taste for much drier habitats such as the sandhills of peninsular Florida, the new species, called Antaeotricha floridella, is a noteworthy case among the moths and butterflies. This kind of endemism is, however, quite common among other groups of insects and spineless animals.

Initially confused with another very similar and widely distributed species, called Antaeotricha albulella, the herein described moth was found to be actually quite different when dissected by co-author Terhune Dickel.

After Mr. Dickel showed specimens to Dr. Hayden, they noticed that its forewings are immaculately white, unlike those of its close relatives within the pale-coloured endemics for the New World. Their wings tend to differ in colouration on a species level and are often spotted, however minute these contrasting patterns might be. While the new species has its forewings always in snow-white on the upper side and its hindwings – in pale gray, its kin, A. albulella, has either one or two black spots of black on its own forewings and white or pale-gray hindwings.

Currently, not much is known about the new moth species’ feeding habits. The evergreen sand live oak is the only plant that it has so far been confirmed to feed on. However, the researchers do not exclude the possibility that the new species could use a wider variety of oaks as hosts.

The occurrence of the moth exclusively in the dry areas of peninsular Florida fits an ecological pattern, and it is likely that more species, currently assigned under incorrect names, will be found in the state’s sandhills and scrub.
