A new study provides seventeen records of the cuckoo wasp genus Cleptes from China, nine of which are beautifully coloured new to science species. The study, published in the open access journal ZooKeys, is the first revision of the genus from China, providing morphological data and illustrations.

The revised genus belongs to the engaging cuckoo wasp family Chrysididae. As their common name suggests, these wasps have some peculiar parasitoid nesting habits. Often highly sculptured, with brilliantly colored metallic-like bodies they are also called jewel wasps, gold wasps, or emerald wasps.

Just like the cuckoo the wasps sneak in and lay their eggs in host nests. When hatched the larvae consume the host egg or larva, while they are still young, and after eliminating competition they move onto consuming the provisions. The members of the genus revised are parasitoids of the prepupae of sawflies.

Another interesting survival mechanism of the cuckoo wasps is their ability to curl into a protective ball when in danger, a process known as conglobation. In nature this mechanism is also seen in pill bugs and armadillos.

“Relatively thoroughly studied in Europe and North America, there are only a few and non-systematic studies for Asia. In China, the fauna of Cleptes is still very poorly known. This study is the first revision of the genus there, recognising seventeen species, nine of which are new to science, and marking the road for future studies.” comments Zai-fu Xu, South China Agricultural University.

Wasps, bees, ants and relatives comprise the megadiverse insect order Hymenoptera, the third most speciose animal group on Earth, far surpassing the number of known vertebrate species. All the four most diverse orders of animals (beetles, butterflies, wasps, and true flies) belong to the group of insects with complete metamorphosis, i.e. having a dormant pupa, jointly known as Holometabola. Other holometabolans are lacewings, alderflies, dobsonflies, snakeflies, scorpionflies, fleas, and caddisflies. Hymenopterans are currently regarded as a very old lineage, which had been the first to separate from the holometabolan stem, the view supported by molecular evidence.

Eighty years ago the Russian entomologist Andrey Martynov—well known for naming the two major divisions of winged insects Palaeoptera and Neoptera, stressing the importance of the wing folding pattern for insect evolution—suggested that wasps had arisen from snakefly-like ancestors.

New fossils, which are 260–270 million years old, support his view, firmly attaching the wasp lineage to the lacewing (neuropteroid) branch of the holometabolan family tree and dating its origin no earlier than Late Permian. These fossils are the oldest known Megaloptera: alderfly-like Parasialidae, and a newly discovered closely related family Nanosialidae.

Dr. Dmitry Shcherbakov, a fossil insect specialist at the Arthropoda Lab, founded by Martynov at the Borissiak Paleontological Institute, Russian Academy of Sciences, Moscow argues that parasialids gave rise to both wasps and nanonosialids, and the latter became the ancestors of snakeflies. Living alderflies, dobsonflies, and snakeflies represent remnants of the past diversity of archaic neuropteroids, which presumably had diverse lifestyles. The study was published in the open access journal ZooKeys.

Parasialids were small to medium-sized; nanosialids were minute creatures 3–5 mm long and probably fed on jumping plant lice, common in the same fossil fauna. The earliest wasps, known from the mid-Triassic (about 240 million years ago), were rather small, too. “It appears that, early in their history,” the author says, “the lineages of Megaloptera, Raphidioptera and Hymenoptera experienced miniaturization, which profoundly and irreversibly affected their body structure.”

Scientists from the Smithsonian Institution describe the Spectacular Guyane False-form beetle, or Guyanemorpha spectabilis, from Guyane (French Guiana). As its name suggests, the newly discovered species stands out among its dull relatives in the Western Hemisphere, with its great size and beautiful coloration. The study was published in the open access journal ZooKeys.

“This surprising large and colorful pseudomorphine came as a shock to me, as all other species of the Tribe in the Western Hemisphere are quite dull brown, dark reddish, or blackish with no, or little, color contrast on the upper surface.” explains the author Dr. Terry L. Erwin. “In the world of entomology this new species can be only compared in its rare characteristics to the Olinguito, a new carnivore species which charmed the world and just recently described by Kris Helgen in ZooKeys. ” he added.

The new species belongs to the Pseudomorphini Tribe, famous for the co-existence of its representatives with various ant species. Members of G. spectabilis occur at lowland rainforest sites in French Guiana and are accordingly most likely to live with ants, although at present nothing is known about their way of life.

“The pseudomorphines are a very interesting evolutionary off-shoot of the normal carabid morphotype in both form and function and are only just now beginning to be understood in North America. The fact that species of related genera in South America are living with arboreal ants will make learning about them far more difficult. Insecticidal fogging gets adults of these species, but only tearing apart arboreal Azteca ant nests while suspended in a tree will produce their larvae, and that is not for carabidologists faint of heart.” explains the author Dr. Erwin, and his Intern, Lauren Amundson.

Bucknell professor Chris Martine never expected to be working with his mentor on identifying a new wild eggplant in Australia, especially since Martine’s former colleague passed away years ago

Bucknell University biology professor Chris Martine has discovered and described a new species of wild eggplant, found in Australia’s Lost City. Martine, who named the plant Solanum cowiei, recently detailed his findings in the journal PhytoKeys.

Martine described the plant as “gender bending,” and explained that the females actually pretend to be male by producing pollen.

“What they’re really doing is duping bees into visiting their flowers.” Martine said. “One of the things we’re going to do next is study what that means. Do the bees actually get anything from this fake pollen? And, if they don’t, that means the plants are actually tricking the bees into doing their bidding, which would be a really neat thing for a plant to do.”

Listed as a co-discoverer is David Symon, who mentored Martine while he was pursuing his doctorate in the early 2000s. Martine’s graduate research focused on varieties of wild eggplants in Australia — Symon’s area of expertise. The two began a long-distance correspondence, with Martine sending Symon emails and Symon, who at the time was nearly 90, returning handwritten replies by mail. In 2004, they teamed up on a field expedition to search for new plant species in the Outback.

After the research trip, the two parted ways. Martine traveled with another group of researchers to Western Australia, and Symon stayed behind to examine specimens in Australia’s Northern Territory Herbarium. It was the last time they would ever see each other.

Martine continued his work in Australia in 2009, which is when he first came across what is now known as Solanum cowiei. While DNA tests confirmed that the plant was an unknown species, Martine lacked the flowers he needed to assign it a scientific name.

Martine returned to Australia for a third time last May, hoping to find the elusive eggplants in bloom. He traveled to Litchfield National Park, where Martine had previously spotted the species. A wildfire had recently scorched the area, making it easier to pick out green sprouts amidst the gray and brown landscape. Combing through the brush, Martine found the wild eggplant with budding flowers.

“If I was capable of doing backflips, I would have done them,” Martine said. “The only issue was that this was supposed to be our last day in the field and not a single bud had opened. We extended our time in the bush and camped out for two more nights, but they never opened.”

Martine made his way back to the Northern Territory Herbarium, the same place he had last worked with Symon a decade earlier. He was elated to discover specimens of the plant with flowers on them. The find meant he could return to Bucknell to complete his description of the new species.

A day before heading home to America, Martine decided to dig deeper into the herbarium’s archives, hoping others had come across the mystery plant and recorded their own observations. He was shocked by what he found: some dried specimens, and a page of handwritten notes that Martine easily recognized from his correspondence so many years ago. Unbeknownst to Martine, his mentor Symon had started describing Solanum cowiei after their trip together in 2004; it is the first known attempt to describe the eggplant Martine is now credited with naming.

“I knew right away that the notes were David’s — and I can say without exaggeration that finding them gave me the chills.” Martine said. “Of course, then all I could do for a good ten minutes was sit there with a big smile on my face, shaking my head; he had beaten me to it.”

But Symon was never able to describe the species.

“He likely stopped short of publishing the new species for the same reason I have until now.” Martine explained. “Under the heading ‘female flowers’ he wrote – not seen. ”

Notes:

The name Solanum cowiei is in honor of botanist Ian Cowie of the Northern Territory Herbarium, who first showed Martine dried specimens of the formerly undescribed species. Also listed as an author on the recent publication is Bucknell University professor Elizabeth Capaldi Evans, who traveled to Australia with Martine in May, 2013.

Two new beautiful wasp species are added to the rare pompilid genus Abernessia, which now contains a total of only four known species. The two new species A. prima and A. capixaba are believed to be endemic for Brazil alongside the rest of the representatives of the genus. Both wasps are distinguished by the large size (almost 3cm in length) and the beautiful black color with metallic shine typical for the family. The study was published in the open access journal ZooKeys.

The enigmatic genus Abernessia is part of the spider wasp family Pompilidae. Spider wasps take their name from the preference of the representatives to parasitize spiders. The females paralyze the prey by stinging it, which is then put in a specifically built nest. The female then lays a single egg on the abdomen of the spider and bury it carefully marking any signs that might give away the nest.

Interestingly it is believed to have a connection between the sizes of prey and size of the offspring of the wasps, the lager wasps are believed to appear from nests containing larger prey.

“There is a positive correlation between size of the spider preyed and size of the wasp produced in the next generation.” comments Dr. Waichert, Utah State University.

The lowland tropics were once though filled with widespread species, while moderate and higher elevations were thought to contain species with more restricted distributions. That idea is turning out to be partially incorrect. Widespread species now appear to be the exception, instead of the rule. A new study describes four species once considered to be the collared treerunner, a lizard known to the scientific community as Plica plica. The study was published in the open access journal ZooKeys.

The collared treerunner was originally described in 1758 and has been the subject of many biological, ecological, and behavioral studies in recent years. A new ZooKeys paper by John C. Murphy, Field Museum (Chicago) and Michael J. Jowers, Estación Biológica de Doñana (Sevilla, Spain) describe four new species formerly thought to be one.

“The collard treerunner was considered a single species ranging from Trinidad and Tobago and northern Venezuela southward into the Amazon Basin, south of the Amazon River.” Murphy said. ” The Treerunners ancestor diverged about 25-30 million years ago, and throughout this time the South American continent has undergone dramatic remodeling, including the rise of the Andes, rising and falling sea levels, and changing climates that isolated populations for long periods of time, allowing them to become new species. Treerunners live on vertical surfaces, such as tree trunks, rock walls, and even buildings and they eat a variety of insects.”

The new paper focuses on populations of this lizard in northern South America, but in an overall survey the authors examined specimens from across the Amazon basin and suspect there may be at least another five to seven undescribed species in what is currently considered the collared treerunner. The treerunners from Trinidad and northern Venezuela were 4.5% genetically different from those in southern Venezuela, and more than 5% different from those in Brazil. For comparison purposes humans and chimpanzees are less than 2% genetically different.

While some species may form by genetic divergence without showing any morphological differences from their ancestor, other often show subtle or obvious morphological differences that may be quite easy to detect. The latter is the case with the collard treerunners.

Some had as few as 92 scales around the body while others had 202 scales around the body. Some adult males have yellow heads while other have red heads, some have distinctive patterns of spots while others have transverse bands.

Unraveling cryptic species is important for a more complete understanding of biodiversity, evolution, and for long term conservation efforts.

The take home message here is that there are many more species of squamate reptiles (lizards and snakes) in the world than previously thought, and it is likely many species have and will disappeared before science is even aware of them. Cutting forests and draining swamps undoubtedly causes extinctions of the species depending upon those habitats. While none of the treerunners described in this paper are likely to be threatened with extinction this discovery and many other similar recent discoveries suggest our knowledge of biodiversity is lacking.

For many decades, researchers thought the closest relatives of papaya were certain trees from the Andes, the so-called highland papayas. A study employing DNA sequences from all species of the papaya family instead revealed that the closest relatives of papaya are three herbaceous species and a small tree with stinging hairs occurring from Mexico to Guatemala and El Salvador. The stingy-haired tree in fact is only known from cloud forests in the Sierra de Juarez in Oaxaca, southern Mexico.

The three herbaceous species are well known to Mexicans living in the area, and Mexican botanists had figured out their correct names some time ago. This was overlooked, however, in the most recent treatment, resulting in an erroneous merging and choice of names of two species.

In a paper published in PhytoKeys, Carvalho and Renner clarify the species boundaries, illustrate the least known species, and provide a key to all taxa comprising the papaya sister group.

“Before our studies the closest relatives of papaya were known only by local people living along the areas where these plants are growing. These people could never imagine they were eating a close relative of the famous papaya because the fruits and leaves are very unlike.”comments Dr. Carvalho. “For some people is hard to believe that the highland papayas from the Andes are not closer related to papaya than are these Mesoamerican herbs. However, the fact that the closest relatives of papaya are endemic to Central America coincides with the distribution of the wild-form of the crop, which has much smaller fruits and thinner pulp than the ones we can buy in supermarkets.”

Scientists discover three new gorgeous species of the wafer trapdoor genus Fufius – F. minusculus, F. jalapensis, and F. candango. The discovery of the three new species, published in the open access journal ZooKeys, paves the road to understanding the morphological variability of the species in this little known mygalomorph genus.

The family Cyrtaucheniidae is a widespread family of spiders, known also as wafer trapdoor spiders. Many, but not all, make wafer-like doors to their burrows, while others build the cork-like doors found commonly in the true trapdoor spiders. Little is known about the biology of the enigmatic genus Fufius, but among the curiosities is that instead of burrows these spiders live in silken tubes in crevices, carefully prolongued with silk.

The mygalomorph neotropical genus Fufius comprises ten species, widely distributed distributed from Guatemala in Central America to southeastern Brazil, in South America. This new study describes three beautiful new species from Brazil, alongside the re-description of the previously known F. funebris and the first description of a female F. lucasae.

“What is curious about the genus Fufius is the wide distribution of the species. Normally, mygalomorphs have a very restricted distribution. Furthermore, the genus has species living in contrasting environments as the Amazon, Savannah, and Brazilian Atlantic forest. This makes the genus a potential model for biogeographic studies.” comments one of the authors Dr. Rogerio Bertani.

“The relationship with other mygalomorph spiders is also unclear, and several authors considered the genus to belong in very distinct families. The 3 new species described in the paper as well as the redescription of an old species and the description of a female of another species formerly known from male specimen aids in understanding the morphological variability of the species in this little known mygalomorph genus.” concludes Dr. Bertani.

Currently, butterfly populations in many countries decline at alarming rates. Many of these populations are closely associated with the agricultural landscape. Changes in farming practices and land use can therefore have far-reaching consequences for the success and persistence of the butterfly fauna. A research team from Sweden and Germany have now reviewed effects of land management on butterfly diversity using historical and current surveys during the last 100 years.

The study focuses on systematic surveys of butterfly population trends and extinction rates in southern Swedish agricultural landscapes. In some areas, half of the butterfly fauna has been lost during the last 60-100 years. The study is published in the journal Nature Conservation.

Land use in these parts of northern Europe has changed markedly with key butterfly habitats such as hay meadows disappearing at alarming rates. Grazed, mixed open woodlands have been transformed into dense forests and domestic grazers have been relocated from woodlands to arable fields and semi-natural grasslands. Hay and silage harvest now start much earlier in the season which reduces the time available for larval development. The changed and intensified land use has also markedly reduced the availability of nectar resources in the landscape. Adding to these problems, current agricultural subsidy systems favour intensive grazing on the remaining semi-natural grasslands, with strong negative effects on butterfly diversity.

While the documented changes in farming practises and land use are problematic for the butterfly fauna, relatively minor adjustments to land management have a potential of drastically counteracting these effects. In order to mitigate risks of further species loss and to work towards recovery of threatened butterfly populations, the review ends by recommending twelve management measures favourable for many butterflies. Examples include later grazing, rotational grazing with parts of semi-natural grasslands grazed only in late summer in some years, and careful choice of grazers.

Researchers from the University of New England (Australia) and the Royal Botanic Gardens and Domain Trust, Sydney (Australia), have discovered a high-altitude species of sedge from south-western Tasmania. A small clumping plant, Lepidosperma monticola grows on mountains including Mount Field and Mount Sprent. It is unique in the genus in being the only species essentially restricted to alpine vegetation. At less than seven centimeters tall, this Tasmanian endemic is also the smallest known species of Lepidosperma.

Mr. George Plunkett and Prof. Jeremy Bruhl (University of New England), and Assoc. Prof. Karen Wilson (Royal Botanic Gardens and Domain Trust, Sydney) described this new species in the open access journal PhytoKeys.

Mr. Plunkett, who is undertaking a PhD on Lepidosperma, first discovered the new species amongst herbarium specimens on loan to the N.C.W. Beadle Herbarium from the Tasmanian Herbarium. A field trip to Tasmania to collect additional material, observe the species in the wild and examine relevant collections at the Tasmanian Herbarium provided further evidence supporting the recognition of Lepidosperma monticola as a new species. Analysing the morphological and anatomical attributes of the plants demonstrated conclusively that L. monticola is a distinct species in need of formal recognition.

Species of the genus Lepidosperma, commonly known as sword-sedges, mostly have elongate, flattened leaves that are shaped like a double-edged sword. Many also possess sharp, cutting leaf margins, alluding to this common name. The genus with more than 100 species is widespread across Australia. It is of particular ecological interest because its fruits are removed by ants after falling. The authors are also working with colleagues from University of Sydney to investigate the taxonomic value of aromatic resins, which also appear to have therapeutic value.

Most species of Lepidosperma occur in open forests, woodlands and heath, and some in swamps, but L. monticola is essentially restricted to alpine vegetation. All known populations of this new species occur above 700 m altitude. Individual plants are often inconspicuous, growing in the crevices of rock outcrops. Other individuals form attractive rounded clumps up to about 20 cm in diameter intermingled with mosses and lichens.

Lepidosperma monticola is somewhat similar to a previously named species, L. inops, which grows at lower elevations. The two species can be readily distinguished by traits such as fruit morphology. Ongoing work by the authors and collaborators is likely to uncover additional undescribed species of Lepidosperma.
