A beautiful non-venomous snake, previously unknown to science, was discovered in Paraguay and described by researchers of the Paraguayan NGO Para La Tierra with the collaboration of Guyra Paraguay and the Instituto de Investigación Biológica del Paraguay. It belongs to the genus Phalotris, which features 15 semi-subterranean species distributed in central South America. This group of snakes is noted for its striking colouration with red, black, and yellow patterns.
Jean-Paul Brouard, one of the involved researchers, came across an individual of the new species by chance while digging a hole at Rancho Laguna Blanca in 2014. Together with his colleagues Paul Smith and Pier Cacciali, he described the discovery in the open-access scientific journal Zoosystematics and Evolution. The authors named it Phalotris shawnella, in honour of two children – Shawn Ariel Smith Fernández and Ella Bethany Atkinson – who were born in the same year as the Fundación Para La Tierra (2008). They inspired the founders of the NGO to work for the conservation of Paraguayan wildlife, in the hope that their children can inherit a better world.

The new Phalotris snake is particularly attractive and can be distinguished from other related species in its genus by its red head in combination with a yellow collar, a black lateral band and orange ventral scales with irregular black spots. Only known from three individuals, it is endemic to the Cerrado forests of the department of San Pedro in east Paraguay. Its known distribution consists of two spots with sandy soils in that department – Colonia Volendam and Laguna Blanca – which are 90 km apart.

The extreme rarity of this species led the authors to consider it as “Endangered”, according to the conservation categories of the International Union for Conservation of Nature (IUCN), which means it is in imminent danger of extinction in the absence of measures for its protection.

This species can only be found in the famous tourist destination of Laguna Blanca, an area declared as an Important Area for the Conservation of Amphibians and Reptiles.

“This demonstrates once again the need to protect the natural environment in this region of Paraguay,” the authors comment. “Laguna Blanca was designated as a Nature Reserve for a period of 5 years, but currently has no protection at all. The preservation of this site should be considered a national priority for conservation.”

The plant – unique with its showy, intense yellow flowers – was described by Polish orchidologists in collaboration with an Ecuadorian company operating in orchid research, cultivation and supply.
An astounding new species of orchid has been discovered in the cloud rainforest of Northern Ecuador. Scientifically named Maxillaria anacatalina-portillae, the plant – unique with its showy, intense yellow flowers – was described by Polish orchidologists in collaboration with an Ecuadorian company operating in orchid research, cultivation and supply.

Known from a restricted area in the province of Carchi, the orchid is presumed to be a critically endangered species, as its rare populations already experience the ill-effects of climate change and human activity. The discovery was aided by a local commercial nursery, which was already cultivating these orchids. The study is published in the open-access journal PhytoKeys.
During the past few years, scientists from the University of Gdańsk (Poland) have been working intensely on the classification and species delimitations within the Neotropical genus Maxillaria – one of the biggest in the orchid family. They have investigated materials deposited in most of the world’s herbarium collections across Europe and the Americas, and conducted several field trips in South America in the search of the astonishing plants.

The first specimens of what was to become known as the new to science Maxillaria anacatalina-portillae were collected by Alex Portilla, photographer and sales manager at Ecuagenera, an Ecuadorian company dedicated to orchid research, cultivation and supply, on 11th November 2003 in Maldonado, Carchi Province (northern Ecuador). There, he photographed the orchid in its natural habitat and then brought it to the greenhouses of his company for cultivation. Later, its offspring was offered at the commercial market under the name of a different species of the same genus: Maxillaria sanderiana ‘xanthina’ (‘xanthina’ in Latin means ‘yellow’ or ‘red-yellow’).
In the meantime, Prof. Dariusz L. Szlachetko and Dr. Monika M. Lipińska would encounter the same intriguing plants with uniquely colored flowers on several different occasions. Suspecting that they may be facing an undescribed taxon, they joined efforts with Dr. Natalia Olędrzyńska and Aidar A. Sumbembayev, to conduct additional morphological and phylogenetic analyses, using samples from both commercial and hobby growers, as well as crucial plants purchased from Ecuagenera that were later cultivated in the greenhouses of the University of Gdańsk.
As their study confirmed that the orchid was indeed a previously unknown species, the scientists honored the original discoverer of the astonishing plant by naming it after his daughter: Ana Catalina Portilla Schröder.

On the one hand, the publication is remarkable because of the large number of new species of frogs. Regarding vertebrate animals, most studies only list between one and five new to science species, because of the difficulty of their collection and the copious amount of work involved in the description of each. To put it into perspective, the last time a single article dealt with a similar number of newly discovered frogs from the western hemisphere was in 2007, when Spanish scientist Ignacio de la Riva described twelve species from Bolivia.
The Rain frogs comprise a unique group lacking a tadpole stage of development. Their eggs are laid on land and hatch as tiny froglets. Image by BIOWEB-PUCE.
On the other hand, the new paper by Nadia Paez and Dr Santiago Ron is astounding due to the fact that it comes as part of the undergraduate thesis of Nadia Paez, a former Biology student at the Pontifical Catholic University, where she was supervised by Professor Santiago Ron. Normally, such a publication would be the result of the efforts of a large team of senior scientists. Currently, Nadia Paez is a PhD student in the Department of Zoology at the University of British Columbia in Canada.
Unfortunately, amongst the findings of concern is that most of the newly described frog species are listed as either Data Deficient or Threatened with extinction, according to the criteria of the International Union for Conservation of Nature (IUCN). All of the studied amphibians appear to have very restricted geographic ranges, spanning less than 2,500 km2. To make matters worse, their habitats are being destroyed by human activities, especially cattle raising, agriculture, and mining.
Amongst the newly described species, there is the peculiar Multicolored Rain Frog, where the name refers to its outstanding color variation. Individuals vary from bright yellow to dark brown. Initially, the studied specimens were assumed to belong to at least two separate species. However, genetic data demonstrated that they represented a single, even if highly variable, species.

The rest of the previously unknown frogs were either named after scientists, who have made significant contributions in their fields, or given the names of the places they were discovered, in order to highlight places of conservation priority.

A novel approach relying on a short sequence of mitochondrial DNA in conjunction with a lateral image of the holotype specimen was proposed to greatly accelerate species identification and description, especially when it comes to hyperdiverse taxa, such as parasitic wasps.
At today’s rate, it could take another two millennia for science to document all currently existing species of multicellular life
Two hundred and sixty-one years ago, Linnaeus formalized binomial nomenclature and the modern system of naming organisms. Since the time of his first publication, taxonomists have managed to describe 1.8 million of the estimated 8 to 25 million extant species of multicellular life, somewhere between 7% and 22%. At this rate, the task of treating all species would be accomplished sometime before the year 4,000. In an age of alarming environmental crises, where taking measures for the preservation of our planet’s ecosystems through efficient knowledge is becoming increasingly urgent, humanity cannot afford such dawdling.
“Clearly something needs to change to accelerate this rate, and in this publication we propose a novel approach that employs only a short sequence of mitochondrial DNA in conjunction with a lateral image of the holotype specimen,”
Description rate of parasitic wasps species (superfamily Ichneumonoidea). Data from Taxapad (Yu et al. 2016).
In standardized practices, it is required that experts conduct plenty of time- and labor-consuming analyses, in order to provide thorough descriptions of both the morphology and genetics of individual species, as well as a long list of characteristic features found to differentiate each from any previously known ones. However, the scientists argue, at this stage, it is impossible to pinpoint distinct morphological characters setting apart all currently known species from the numerous ones not yet encountered. To make matters worse, finding human and financial resources for performing this kind of detailed research is increasingly problematic.
This holds especially true when it comes to hyperdiverse groups, such as ichneumonoid parasitoid wasps: a group of tiny insects believed to comprise up to 1,000,000 species, of which only 44,000 were recognised as valid, according to 2016 data. In their role of parasitoids, these wasps have a key impact on ecosystem stability and diversity. Additionally, many species parasitise the larvae of commercially important pests, so understanding their diversity could help resolve essential issues in agriculture.
Meanwhile, providing a specific species-unique snippet of DNA alongside an image of the specimen used for the description of the species (i.e. holotype) could significantly accelerate the process. By providing a name for a species through a formal description, researchers would allow for their successors to easily build on their discoveries and eventually reach crucial scientific conclusions.
“If this style were to be adopted by a large portion of the taxonomic community, the mission of documenting Earth’s multicellular life could be accomplished in a few generations, provided these organisms are still here,”
say the authors of the study.
To exemplify their revolutionary approach, the scientists use their paper to also describe a total of 18 new species of wasps in two genera (Zelomorpha and Hemichoma) known from Área de Conservación Guanacaste, Costa Rica. Currently, the team works on the treatment of related species, which still comprise only a portion of the hundreds of thousands that remain unnamed.

Gaming and virtual reality could bridge the gap between urban societies and nature, thereby paving the way to insect conservation by the means of education and participation. This is what an interdisciplinary team at Florida International University strive to achieve by developing a virtual reality game (desktop version also available) dedicated to insect and plant species. Focused on imperiled butterflies, their innovative idea: Butterfly World 1.0, is described in the open-access journal Rethinking Ecology.

Gaming and virtual reality (VR) could bridge the gap between urban societies and nature, thereby paving the way to insect conservation by the means of education, curiosity and life-like participation.
This is what Florida International University‘s team of computer scientist Alban Delamarre and biologist Dr Jaeson Clayborn strive to achieve by developing a VR game (desktop version also available) dedicated to insect and plant species. Focused on imperiled butterflies, their innovative idea: Butterfly World 1.0, is described in the open-access journal Rethinking Ecology.

Butterfly World 1.0 is an adventure game designed to engage its users in simulated exploration and education. Set in the subtropical dry forest of the Florida Keys (an archipelago situated off the southern coast of Florida, USA), Butterfly World draws the players into an immersive virtual environment where they learn about relationships between butterflies, plants, and invasive species. While exploring the set, they interact with and learn about the federally endangered Schaus’ swallowtail butterfly, the invasive graceful twig ant, native and exotic plants, and several other butterflies inhabiting the dry forest ecosystem. Other nature-related VR experiences, including conservation awareness and educational programs, rely on passive observations with minimal direct interactions between participants and the virtual environment.
According to the authors, virtual reality and serious gaming are “the new frontiers in environmental education” and “present a unique opportunity to interact with and learn about different species and ecosystems”.

The major advantage is that this type of interactive, computer-generated experience allows for people to observe phenomena otherwise impossible or difficult to witness, such as forest succession over long periods of time, rare butterflies in tropical dry forests, or the effects of invasive species against native wildlife.
“Imagine if, instead of opening a textbook, students could open their eyes to a virtual world. We live in a time where experiential learning and stories about different species matter, because how we feel about and connect with these species will determine their continued existence in the present and future. While technology cannot replace actual exposure to the environment, it can provide similar, near-realistic experiences when appropriately implemented,” say the scientists.
In conclusion, Delamarre and Clayborn note that the purpose of Butterfly World is to build knowledge, reawaken latent curiosity, and cultivate empathy for insect and ecosystem conservation.

The endemic reptiles are already proposed to be listed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora
While proper information about the conservation status of tiger gecko species is largely missing, these Asian lizards are already particularly vulnerable to extinction, as most of them have extremely restricted distribution. Furthermore, they have been facing severe declines over the last two decades, mostly due to overcollection for the international exotic pet market. Such is the case of the Cat Ba Tiger Gecko, whose tiny populations can only be found on Cat Ba Island and a few islands in the Ha Long Bay (Vietnam).
In their study, a Vietnamese-German research team, led by PhD candidate Hai Ngoc Ngo of the Vietnam National Museum of Nature in Hanoi, provide an overview of the evidence for domestic and international trade in tiger gecko species and update the information about the abundance and threats impacting the subpopulations of the Vietnamese Cat Ba Tiger Gecko in Ha Long Bay.
By presenting both direct and online observations, interviews and existing knowledge, the scientists point out that strict conservation measures and regulations are urgently needed for the protection and monitoring of all tiger geckos. The research article is published in the open-access journal Nature Conservation.

Tiger geckos are a genus (Goniurosaurus) of 19 species native to Vietnam, China and Japan. Many of them can only be found within a single locality, mountain range or archipelago. They live in small, disjunct populations, where the population from Ha Long Bay is estimated at about 120 individuals. Due to demands in the international pet trade in the last two decades, as well as habitat destruction, some species are already considered extinct at the localities where they had originally been discovered.
However, it was not until very recently that some species of these geckos received attention from the regulatory institutions in their home countries, leading to the prohibition of their collection without a permit. Only eight tiger geckos have so far had their species conservation status assessed for the IUCN Red List. Not surprisingly, all of them were classified as either Vulnerable, Endangered or Critically Endangered. Nevertheless, none is currently listed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which could be the only efficient and reliable method to monitor, regulate and police the trade of the species on a global scale.
“Tiger geckos are neither sufficiently protected by law nor part of conservation programmes, due to the lack of substantial knowledge on the species conservation status and probably due to the general lack of public as well as political interest in biodiversity conservation,” they explain. “To date, exact impacts of trade on the species cannot be identified, as data of legal trade are only recorded for species listed in the CITES Appendices”.
During their survey, the researchers tracked local traders in possession of wild-caught tiger geckos representing all five Vietnamese species en route to foreign exotic pet markets, mainly in the United States, the European Union and Japan. The species were also frequently found to be sold in local pet shops in Vietnam, as well as being offered via various online platforms and social media networks like Facebook.
Having spoken to local dealers in Vietnam, the team found the animals were traded via long and complex chains, beginning from local villagers living within the species’ distribution range, who catch the geckos and sell them to dealers for as little as US$4 – 5 per individual. Then, a lizard either ends up at a local shop with a US$7 – 25 price tag or is either transported by boat or by train to Thailand or Indonesia, from where it is flown to the major overseas markets and sold for anywhere between US$100 and 2,000, depending on its rarity. However, many of these delicate wild animals do not arrive alive at their final destination, as their travels include lengthy trips in overfilled boxes under poor conditions with no food and water.
Indeed, although the researchers reported a large quantity of tiger geckos labelled as captive-bred in Europe, it turns out that their availability is far from enough to meet the current demands.
In conclusion, the team provides a list of several recommendations intended to improve the conservation of the Asian geckos: (1) inclusion of all tiger geckos in the Appendices of CITES; (2) assessment of each species for the IUCN Red List; (3) concealment of any currently unknown localities; and (4) improvement/establishment of coordinated ex-situ breeding programmes for all species.
Signboard handed over to the Ha Long Bay Management Department to point to the threats and conservation need of the Cat Ba tiger gecko in English and Vietnamese languages.
The inclusion of all tiger gecko species from China and Vietnam in CITES Appendix II was recently proposed jointly by the European Union, China and Vietnam and is to be decided upon at the Conference of the parties (CoP18) in May-June 2019, held in Sri Lanka.

Earlier this year, a research article triggered a media frenzy by predicting that as a result of an ongoing rapid decline, nearly half of the world’s insects will be no more pretty soon
Query- and geographically-biased summaries; mismatch between objectives and cited literature; and misuse of existing conservation data have all been identified in the alarming study, according to Drs Atte Komonen, Panu Halme and Janne Kotiaho of the University of Jyväskylä (Finland). Despite the claims of the review paper’s authors that their work serves as a wake-up call for the wider community, the Finnish team explain that it could rather compromise the credibility of conservation science.
The first problem about the paper, titled “Worldwide decline of the entomofauna: A review of its drivers” and published in the journal Biological Conservation, is that its authors have queried the Web of Science database specifically using the keywords “insect”, “decline” and “survey”.
“If you search for declines, you will find declines. We are not questioning the conclusion that insects are declining,” Komonen and his team point out, “but we do question the rate and extent of declines.”
Many butterflies have declined globally. Scolitantides orion, for example, is an endangered species in Finland. Photo by Atte Komonen.
The Finnish research team also note that there are mismatches between methods and literature, and misuse of IUCN Red List categories. The review is criticised for grouping together species, whose conservation status according to the International Union for Conservation of Nature (IUCN) is Data Deficient with those deemed Vulnerable. By definition, there are no data for Data Deficient species to assess their declines.
In addition, the review paper is seen to use “unusually forceful terms for a peer-reviewed scientific paper,” as the Finnish researchers quote a recent news story published in The Guardian. Having given the words dramatic, compelling, extensive, shocking, drastic, dreadful, devastating as examples, they add that that such strong intensifiers “should not be acceptable” in research articles.
“As actively popularising conservation scientists, we are concerned that such development is eroding the importance of the biodiversity crisis, making the work of conservationists harder, and undermining the credibility of conservation science,” the researchers explain the motivation behind their response.

For decades, it has been assumed that the Chinese Softshell Turtles from East Asia all belonged to one and the same species, Pelodiscus sinensis. Widely distributed all the way from the Russian Far East through the Korean Peninsula to China and Vietnam, the species was said to vary substantially in terms of its looks across localities. However, around the turn of the century, following a series of taxonomic debates, scientists revalidated or discovered a total of three species distinct from the ‘original’.
Recently, a Hungarian-Vietnamese-German team of researchers described a fifth species in the genus. Their discovery is published in the open-access journal ZooKeys.
The new species, which differs both genetically and morphologically from the other four, has well-pronounced dark blotches on the underside of its shell. The markings are also the reason why these turtles are going by the scientific name Pelodiscus variegatus, where “variegatus” translates to “spotted” in Latin.
“This morphological feature, among others, led to the discovery that these animals belong to a hitherto undescribed species,” explains Professor Dr. Uwe Fritz of the Senckenberg Natural History Collections in Dresden.
Unfortunately, the identification of multiple species within what used to be a single one has its potentially ill-fated consequences. While the Chinese Softshell Turtle was once considered widespread and not threatened, each newly discovered species “reduces” the individual population numbers.
“When we look at each species, the distribution range as well as the number of individuals is much smaller than when all were combined. Until now, the newly described Spotted Softshell Turtle was considered part of the Lesser Chinese Softshell Turtle Pelodiscus parviformis, which was discovered by Chinese researchers in 1997. Pelodiscus parviformis was already considered critically endangered. Now that its southern representatives have been assigned to a different species, the Spotted Softshell Turtle, the overall population size of each species is even smaller,” explains Balázs Farkas, the study’s Hungarian lead author.
Because of its restricted range and the levels of exploitation it is subjected to, the conservation status of the new species is proposed to be Critically Endangered, according to the criteria of the IUCN Red List of Threatened Species.

A new treefrog species was discovered during a two-week expedition to a remote tabletop mountain at Cordillera del Cóndor, a largely unexplored range in the eastern Andes.
“To reach the tabletop, we walked two days along a steep terrain. Then, between sweat and exhaustion, we arrived to the tabletop where we found a dwarf forest. The rivers had blackwater and the frogs were sitting along them, on branches of brown shrubs similar in color to the frogs’ own. The frogs were difficult to find, because they blended with their background,” Alex Achig, one of the field biologists who discovered the new species comments on the hardships of the expedition.
Curiously, the frog has an extraordinary, enlarged claw-like structure located at the base of the thumb. Its function is unknown, but it could be that it is used either as a defence against predators or as a weapon in fights between competing males.
Having conducted analyses of genetic and morphologic data, scientists Santiago R. Ron, Marcel Caminer, Andrea Varela, and Diego Almeida from the Catholic University of Ecuador concluded that the frog represented a previously unknown species. It was recently described in the open-access journal ZooKeys.

The species name, Hyloscirtus hillisi, honors Dr. David Hillis, a member of the National Academy of Sciences of the United States of America, who discovered three closely related frog species in the same genus in the 1980s, while conducting a series of field trips to the Andes of southern Ecuador. Throughout his career, Dr. Hillis has made significant contributions to the knowledge of Andean amphibians and reptiles.

The existence of five delightfully weird snail-sucking snakes slithering through the forest floors of Ecuador was announced by a group of scientists in a study in the open access journal Zookeys.
Believe or not, there is an entire group of snakes for which snails are number one on their menu. This is why their jaws are modified in such a way that they can suck the viscous slimy body of a snail right out of its shell.

Luckily for us, these snakes are harmless to humans. However, humans are not harmless to them. Four out of the five newly discovered species are already facing the possibility of becoming extinct, as the forest remnants they call home are currently being destroyed.
In a bid to take care after the unfortunate reptiles, the scientists auctioned the naming rights for the new species at a recent event in New York City. The money are to purchase and save a previously unprotected 72 ha (178 acre) plot of land where some of these species live.
To do so, Fundación Jocotoco is to add the purchased plot to the Buenaventura reserve, in order to expand the only protected area where two of the new snakes are found, and prevent these endangered snake species from going extinct.

Three of the five species were discovered during a series of expeditions to three rainforests in Ecuador between 2013 and 2017, conducted by Alejandro Arteaga, an Ecuadorian–Venezuelan PhD student at the American Museum of Natural History and scientific director of Tropical Herping, who partnered with Dr. Alex Pyron, The George Washington University and National Museum of Natural History, USA.
“We had to let people know that these cool snakes exist,” Alejandro said, “and that these species might soon stop to exist, and we need people’s help to protect the snake’s habitat.”
In order to confirm these five snakes as new species, the team of researchers, particularly Drs. Konrad Mebert, Universidade Estadual de Santa Cruz, Nicolás Peñafiel, Universidad Tecnológica Indoamérica, Gabriela Aguiar, Tropical Herping, and Timothy Colston, The George Washington University and National Museum of Natural History, USA, counted scales and gathered measurements from more than 200 museum specimens, and extracted DNA from nearly 100 snakes.
PhD student Alejandro Arteaga measured snake specimens at various museums, including the American Museum of Natural History in New York City.
Having made the highest bid at the auction, Rainforest Trust (RT) and Bob Ridgely got to name three of the five new snakes.
Thus, the species Dipsas georgejetti now honors George Jett, who supported the inception of Fundación Jocotoco’s reserves in Ecuador; while Dipsas bobridgelyi is a tribute to Dr. Robert “Bob” S. Ridgely, a leading ornithologist and distinguished conservationist who helped the establishment of the Buenaventura reserve. Bob, who was at the auction, chose the name Sibon bevridgelyi (Bev Ridgely’s Snail-Eater) to honor his father.

The remaining two snail-eating species, Dipsas oswaldobaezi and D. klebbai, were named after Dr. Oswaldo Báez and Casey Klebba, respectively, in recognition for their passion for Ecuador’s biodiversity and conservation.

“Several companies let you name a star after a loved one,” Alejandro says, “but, generally, such names have no formal validity. Naming an entire species after someone you love or admire is different. With few exceptions, this is the name that both the general public and the whole scientific community will use. So, why not let people choose the name of a species in exchange for a donation that protects its habitat?”

The act of naming species is essential in raising awareness about the existence of a species and its risk of extinction, but it also provides an opportunity to recognize and honor the work of the people and institutions fighting to protect the species.
“Naming species is at the core of biology,” says Dr. Juan M. Guayasamin, co-author of the study and a professor at Universidad San Francisco in Quito. “Not a single study is really complete if it is not attached to the name of the species, and most species that share the planet with us are not described.”
“Everybody knows elephants and orangutans,” says Dr. Martin Schaefer of Fundación Jocotoco, “but some reptiles and amphibians are even more threatened. Yet, we still lack even the basic information to protect them better. This is why the work by scientists is so important; it provides the necessary information to guide our conservation decisions.”
“Through photography or by joining a scientific expedition, the general public can learn more about hidden biodiversity and how threatened it is,” says Lucas Bustamante of Tropical Herping. “This is a model to obtain support for research and conservation while recruiting more environmental ambassadors.”
