Two Rare Orchids, One Vanishing Forest: Ecuador’s Newest Dracula Species

The genus Dracula is one of the more theatrical corners of the orchid world, containing more than 130 species.

A new species of vampire orchid, described in the open-access journal PhytoKeys, was recently discovered in the cloud forests of southwestern Ecuador, and with it comes the long-awaited confirmation of where a second, mysterious species actually lives in the wild.

The genus Dracula is one of the more theatrical corners of the orchid world. It contains more than 130 species, most found in the northern Andes of Colombia and Ecuador, and is known for its dramatic and often dark-coloured flowers with long tails. These blooms are pollinated by small flies rather than by bees or butterflies, that mistake the flower’s lip for a mushroom!

The newly described species, Dracula aguilarii, was found in El Oro Province, in a region of premontane and cloud forest that sits between 900 and 1,200 metres above sea level. Its cream-coloured flowers are suffused with brown-red tones and covered in short, dense hairs. It closely resembles a related species, D. hirtzii, but can be told apart by its blunt-tipped leaves, a deep and broadly rounded cup formed by the fused sepals, and notably shorter tails on those sepals.

The species owes its name to Mario Aguilar, a farmer and orchid enthusiast from El Oro with a remarkable knack for spotting rare orchids in the field. It was Aguilar who first came across a small population of around fifteen plants in a patch of remnant forest near the town of Balsas, more than a decade ago. Researchers later confirmed, through further fieldwork and herbarium comparisons, that his discovery represented a species new to science, and named it in his honour.

Only three populations of Dracula aguilarii are currently known, all within a fairly small area, which has led researchers to recommend the species be classified as Endangered. The forests it depends on are being steadily cleared for cattle pasture, and like many showy orchids, it also faces pressure from illegal collection for the horticultural trade.

Jiménez from a cultivated plant collected near Balsas.

This same study resolves a smaller mystery that has lingered for well over a decade. Dracula soennemarkii was first described in 2012 from a plant bought at a nursery and grown in Sweden, with no idea of where it had originally come from in the wild. The researchers have now traced a wild population of this species to the same general region of El Oro, giving it a confirmed home for the first time. Given that it is known from just a single location, D. soennemarkii has been assessed as Critically Endangered, an even more precarious position than its newly described neighbour.

Together, these findings demonstrate just how much remains to be discovered, and how quickly it could be lost, in Ecuador’s shrinking cloud forests. El Oro Province alone now hosts six recognised species of Dracula, yet only a fraction of its once-extensive humid forest cover remains intact. Each new species description is as much a conservation appeal as it is a taxonomic milestone.

Presence of the rare bat Cormura brevirostris confirmed in Honduras for the first time

The discovery was made through acoustic monitoring in the remote La Moskitia region, an area with historically limited research on bats.

Guest blog post by Manfredo A. Turcios-Casco, José G. Martínez-Fonseca, and Bruce Miller

Honduras has officially documented, for the first time, the presence of Cormura brevirostris—a little-known bat species from the Emballonuridae family, recognizable by a unique vocal pattern of three short calls that rise in frequency. The discovery was made through acoustic monitoring in the remote La Moskitia region of eastern Honduras, an area with historically limited research on bats.

The confirmation comes from two field expeditions carried out between December 2024 and May 2025 in the community of Mavita and within the Warunta Conservation Area, both located in the department of Gracias a Dios. These sites form a mosaic of forests, river corridors, and natural clearings that support specialized and disturbance-sensitive wildlife.

Unlike traditional methods that rely on capturing bats, the identification of Cormura brevirostris was achieved solely through its vocalizations. The acoustic signatures recorded in the field showed clear and consistent patterns that distinguish the species from other bats in the region, allowing for confident confirmation through manual review and comparison with verified acoustic libraries.

During the early stages of processing, some automated systems misidentified the calls as belonging to the genus Molossus. A more detailed examination of call characteristics corrected these misclassifications and verified the presence of Cormura brevirostris. This finding highlights both the power of acoustic monitoring and the importance of expert validation, as automated models alone can produce misleading results.

C. brevirostris is the only species in its genus and is believed to be primarily crepuscular, favoring forest edges and open spaces within lowland tropical rainforest environments. Although past distribution maps and regional checklists hinted at the species’ potential occurrence in Honduras, no confirmed records existed until now.

This new record expands the known range of the species by more than 160 km to the north and raises the number of bat species documented in Honduras to 115. Beyond its scientific significance, the discovery showcases acoustic monitoring as a valuable tool for detecting rare or elusive species in remote, understudied landscapes.

The finding was made possible thanks to collaboration between researchers, conservation organizations, and local communities. In Mavita, the involvement of the Miskitu community and the Apu Pauni project—focused on protecting forests and emblematic wildlife such as the scarlet macaw—has indirectly contributed to the conservation of other species, including bats. The study was supported by the Biodiverse Landscapes Fund (BLF), the Protected Areas and Wildlife Fund (FAPVS), the Wildlife Conservation Society (WCS), and local partners.

The results highlight the importance of strengthening scientific research and community-based conservation in La Moskitia, a strategic region within the Mesoamerican Great Forests, currently threatened by deforestation, illegal cattle ranching, and wildlife trafficking.

A second chance for conservation: lost fish species rediscovered in Bolivia

Researchers have rediscovered Moema claudiae, a species of seasonal killifish in Bolivia that was thought to be possibly extinct. This rediscovery provides new hope for the conservation of this unique fish and the diverse wetland habitats of the region.

Moema claudiae was last seen over 20 years ago in its original locality, in a site now destroyed and converted to agricultural land. Despite extensive surveys in recent years, no other living individuals had been found, and the species was deemed Critically Endangered according to IUCN criteria and thought to be possibly extinct.

However, in a recent expedition, researchers Heinz Arno Drawert and Thomas Otto Litz located a surviving population in a small, temporary pond within a remnant forest patch surrounded by farms.

Published in the open-access journal Nature Conservation, this is the first record of the species in more than two decades and enabled scientists to take the first-ever live photographs, observe its behaviour, and study previously unknown aspects of its natural history.

Thomas Litz, one of the co-authors, said: “For me, it is something special to have rediscovered Moema claudiae. This has shown that we now have the opportunity to preserve this species in the wild. I am all the more pleased because Prof. Wilson Costa named this species after his wife Claudia, and I would like to take this opportunity to thank him especially for decades of collaboration and support.”

The rediscovered habitat harboured not only Moema claudiae but also six other species of seasonal killifish, making it the most genetically diverse assemblage of these fish ever documented worldwide. The region’s unique ecology, where the Amazon forest meets the Llanos de Moxos savannas, appears to support this diversity, but rapid deforestation and agricultural expansion threaten these habitats at an alarming rate.

Following this discovery, scientists emphasise the urgent need to protect the area, as it is now the only known site harbouring a wild population of Moema claudiae, as well as an exceptional global hotspot for seasonal killifish diversity.

Over the last 25 years, nearly 10 million hectares of forest have been lost in Bolivia, including vital wetland habitats. Deforestation has accelerated dramatically in recent years, raising serious concerns for the future of many unique species and ecosystems.

“Without rapid and effective action to curb the irrational expansion of the agricultural frontier in Bolivia’s lowlands, we risk losing some of the world’s most important terrestrial and aquatic ecosystems, and with them the irreplaceable goods and services they provide,” added co-author Heinz Drawert. “We cannot hope to achieve true social and economic wellbeing unless we also maintain the functionality of the ecosystems that sustain it.”

Eaten to extinction: breeding programmes begin for endangered turtles in Vietnam

Considered a delicacy in China and Vietnam, the spotted softshell turtle faces threats from overconsumption and habitat loss.

Conservationists have initiated breeding programmes in Vietnam to recover spotted softshell turtle populations threatened by overconsumption and habitat loss.

Based on a literature study, field surveys across Vietnam, and genetic screenings of collected samples, researchers estimated the range and conservation status of Pelodiscus variegatus, the spotted softshell turtle. The data were then used to model the species’ potential range in Vietnam.

Alarmingly, although several protected areas in Vietnam appear to harbour suitable habitats for the species, no populations were identified in any of the sites, indicating it is especially susceptible to extinction.

To recover natural populations of the species, the Institute of Ecology and Biological Resources and Cologne Zoo, Germany, initiated an in-country breeding programme. In late 2023, they released 50 young and healthy turtles to a site with suitable climate and habitat in northern Vietnam.

It is hoped that additional individuals will be reintroduced to protected areas in north-central Vietnam, the sanctuary of spotted softshell turtles, to reverse its declining trend and further contribute to the global Reverse the Red movement, a target best accomplished by applying the IUCN’s One Plan Approach to Conservation.

Softshell turtles of the genus Pelodiscus are broadly distributed from southeastern Siberia through China to Vietnam. However, their range is currently extended to Indonesia, northern Australia, western Europe, North America, Hawaii, and Mauritius as a result of human transportation and breeding activities.

The turtles are considered a delicacy in China and some Southeast Asian countries. In China alone, each year hundreds of million turtles are traded, making them the most widely consumed turtles in the world.

Traditionally, this genus had been considered monotypic with only one recognised species, the Chinese softshell turtle (Pelodiscus sinensis). However, recent research has shown that the genus is much more diverse with at least seven species known to science.

Due to their morphological similarity, widespread farming activities, overharvesting, and their aquatic lifestyle, it is often difficult to study them in their natural habitat to better understand their distribution as well as their population and conservation status.

Like other congeners, the spotted softshell turtle is facing tremendous threats, from habitat loss to overharvesting for food and genetic pollution because the Chinese softshell turtle has been farmed across the country, imperilling the native genetic sources.

As the result, the Turtle Taxonomy Working Group, the global authority on taxonomic and conservation status of turtles worldwide, provisionally classifies the species as Critically Endangered, the highest ranking for taxa most vulnerable to extinction.

Bouldering in south-central Madagascar: a new “rock-climbing” gecko species of the genus Paroedura

Thanks to recently collected samples, it was described and named after its preferred habitat, the boulders surrounded by the last remaining forests at these sites.

Named after its habitat preference, Paroedura manongavato, from the Malagasy words “manonga” (to climb) and “vato” (rock), is a bouldering expert. Part of its “home range” is also very well-known to rock climbers for its massive granitic domes. “Its description represents another step into the crux (in climbing jargon, the most difficult section of a bouldering problem) of resolving the taxonomy of the recently revised P. bastardi group, where the new species belongs, and reaching a total of 25 described species in this genus, all exclusively living in Madagascar and Comoros,” says C. Piccoli from CIBIO – Research Center in Biodiversity and Genetic Resources, Portugal. She and her team just published a paper describing the new gecko.

Thus far, this species has only been found in Anja Reserve and Tsaranoro, both of which are isolated forest patches in the arid south-central plateau of Madagascar. These sites, at a distance of ca. 25 km, have a peculiar conformation, with huge granitic boulders close to rocky cliffs and surrounded by vegetation. The survival of P. manongavato, defined as microendemic for being restricted to a very narrow distributional range, thus depends on the preservation of these small forest patches. Subsequently, the authors proposed an evaluation of its conservation status as Critically Endangered, a category designated for species threatened of extinction by the International Union for Conservation of Nature.

Its discovery history is long, starting during the Malagasy summer of 2010, when the first evidence of another Paroedura species was found in Anja, together with the recently described P. rennerae in 2021. Distinguishing these two species on the field is a difficult task. Both species have prominent dorsal-enlarged keeled scales and a similar dorsal pattern, although adults of P. manongavato have an overall less spiky appearance, less contrasted dorsal markings, and a smaller body size compared to P. rennerae. The need to collect more samples brought researchers A. Crottini, F. Andreone, and G. M. Rosa to return to Anja in 2014, and collect the future holotype (i.e. the name-bearing and description reference individual) of this new species. Later in 2018, F. Belluardo, J. Lobón-Rovira, and M. Rasoazanany, visited Anja and Tsaranoro again and were able to collect several tissue samples and high-resolution photos of the reptiles living in the area, including the new gecko species. This cumulative data collection was fundamental to advance with its description.

Published in the open access journal ZooKeys, this study highlights the importance of conducting herpetological inventories in Madagascar to improve our understanding of species diversity and progress with species conservation assessments. “The description of this species shows the importance of collaborative efforts when documenting biodiversity, especially for those range-restricted and isolated species at greatest risk of disappearing,” points out the leading author of this study C. Piccoli.

Psychedelic rock gecko among dozens of species in need of further conservation protection in Vietnam

Researchers recommend IUCN CPSG’s One Plan Approach to Conservation measures, which include both habitat conservation and increasing the number of threatened species in breeding stations and zoos.

Further conservation measures are required to protect Vietnamese reptiles, such as the psychedelic rock gecko (Cnemaspis psychedelica), from habitat loss and overharvesting, concludes a new report, published in the open-access scientific journal Nature Conservation.

Having identified areas of high reptile diversity and large numbers of endangered species, the study provides a list of the 50 most threatened species as a guide for further research and conservation action in Vietnam. 

The study, based on the bachelor thesis of Lilli Stenger (University of Cologne, Germany), recommends IUCN CPSG’s One Plan Approach to Conservation measures, which, next to improved habitat conservation, also involves increasing the number of threatened species in breeding stations and zoos to maintain populations suitable for restocking. 

Co-authors of the report are Anke Große Hovest (University of Cologne, Germany), Truong Quang Nguyen (Vietnam Academy of Science and Technology), Cuong The Pham, (Vietnam Academy of Science and Technology), Anna Rauhaus (Cologne Zoo, Germany), Minh Duc Le (Vietnam National University), Dennis Rödder (Leibniz Institute for the Analysis of Biodiversity Change, Germany) and Thomas Ziegler (University of Cologne and Cologne Zoo, Germany).

“Modern zoos, as well as local facilities, can play a crucial role in not only conducting or financially supporting in situ conservation projects, that is to say in nature, but also by protecting species from extinction through maintaining ex situ assurance colonies to reinforce in situ conservation programs,”

said Prof. Dr. Thomas Ziegler, Vietnam conservation team member and coordinator from Cologne Zoo, Germany.

The scientists identified 484 reptile species known to Vietnam, aiming to provide a baseline to authorities, conservationists, rescue centers, and zoos, so they can follow up with appropriate conservation measures for endangered species. They note that the number is likely to go up, as the country is regarded as a top biodiversity hotspot, and the rate of new reptile species discoveries remains high.

According to the IUCN Red List, 74 of the identified species are considered threatened with extinction, including 34 endemic species. For more than half of Vietnam’s endemic reptiles (85 of 159), the IUCN Red List status is either missing or outdated, and further research is imperative for these species, the researchers say.

Vietnam has a high level of reptile diversity and an outstanding number of endemic species. The species richness maps in the study revealed the Central Annamites in central Vietnam to harbor the highest endemic species diversity (32 species), which highlights it as a site of particular importance for reptile conservation. Alarmingly, a protected area analysis showed that 53 of the 159 endemic species (33.2%) including 17 threatened species, have been recorded exclusively from unprotected areas, such as the Psychedelic Rock Gecko.

The Critically Endangered Annam pond turtle (Mauremys annamensis) is one of the most endangered turtle species in Vietnam and in the world. It is not known from any protected area. Despite likely being extinct in the wild,  ex situ conservation programs have been implemented in time with a high number of individuals being kept and bred in zoos and stations and now ready for restocking actions.

In General, Vietnam is considered a country with high conservation priority due to habitat loss and overharvesting for trade, traditional medicine and food.

Globally, reptiles are considered a group of special conservation con­cern, as they play an important role in almost all ecosystems and often have relatively small distri­bution ranges, making them especially vulnerable to human threats.

Endangered vulture returns to Bulgaria after being extinct for 36 years

Preliminary results from the releases of Cinereous Vultures (Aegypius monachus) were published in the Biodiversity Data Journal.

The Cinereous Vulture (Aegypius monachus) – also known as Black Vulture, Monk Vulture or Eurasian Black Vulture – is the largest bird of prey in Europe.

Globally classified as Near Threatened, its populations in southern Europe, once abundant, have been experiencing a dramatic decline since the late 1800s. So dramatic, in fact, that by the mid-1900s, these birds had already been nowhere to be seen throughout most of their distributional range across the Old Continent. In Bulgaria, the species has been considered locally extinct since 1985.

Thanks to the re-introduction initiative that was started in 2015 by three Bulgarian non-governmental organisations: the leading and oldest environmental protection NGO in Bulgaria: Green Balkans, the Fund for Wild Flora and Fauna and the Birds of Prey Protection Society, the species is now back in the country.

The project, aptly named  “Vultures Back to LIFE“, where the Vulture Conservation Foundation (Switzerland), EuroNatur (Germany) and Junta de Extremadura (Spain) are also partners, has been co-financed by the LIFE+ financial instrument of the European Commission.

By mid-2022, the team imported a total of 72 individuals from Spain and European zoos, before releasing them in strategically-chosen sites in the Eastern Balkan Mountains and the Vrachanski Balkan Nature Park in Northwestern Bulgaria. 

The team brought 63 immatures from Spain, where the birds had been found in distress and rehabilitated in aviaries. The other nine juveniles were captive-bred in zoos, and then released by means of hacking, which involves an artificial nest, from where the fledglings can gradually ‘’take off” to a life in the wild.

The re-introduction campaign to date is presented in a research article, published in the open-access Biodiversity Data Journal. There, the scientists led by Ivelin Ivanov (Green Balkans), report on and discuss the effectiveness and challenges of the different release methods and offer tips on the conservation and re-introduction. 

For example, hacking proved to be inefficient for establishing an entirely new core (or nucleus) population of Cinereous Vultures in the Balkan Mountains in Bulgaria. It did not work for supplementing a small settled group of individuals either.

Instead, the team recommend the aviary method and delayed release, where captive-bred birds are introduced to the new locality after a period of acclimatisation, where the birds can gain life experience to the local environment.

 “The Cinereous Vulture re-introduction establishment phase in Bulgaria in the two first release sites is running according to the plan, and the first results are satisfactory,” 

the scientists comment.

“Two distinct nuclei are now created, and the species started breeding, which might be a reason to up-list it in the Red Data Book of Bulgaria from ’Extinct’ to ‘Critically Endangered.’”

These two newly created breeding nuclei of the Cinereous Vulture in Bulgaria are the second and third of their kind in the Balkan Peninsula. 

“Following a dramatic decline throughout the 20th century for decades, the species had remained in only one breeding colony in Dadia-Lefkimi-Soufli Forest National Park in north-eastern Greece. Now, exchange between the three colonies will facilitate the exchange of individuals, ensure long-term stability, and give rise to the regional population,”

the authors of the study say.

However, the team points out that further monitoring and modelling and adaptive management are indispensable for the long-term persistence of the new national population. Now that there is already evidence that the imported vultures have been successfully breeding in Bulgaria, there is one step left before it can be officially confirmed that the Cinereous Vulture species has successfully re-established in the country. This conclusion can only be made after the core breeding populations begin to produce about ten chicks every year and after the locally fledged individuals begin to reproduce on their own. Such results are expected by 2030.

The re-introduction of the Cinereous Vulture is the latest in a series of conservation projects focused on birds of prey in Bulgaria. 

First, in a programme that started in 2009, the Griffon Vulture was successfully re-introduced in Bulgaria after about 50 years of “extinction”. In fact, the team took a lot of the know-how and methods used in that project to apply in the present project. The success story was published in a research paper in the Biodiversity Data Journal in 2021.

The incredible return of Griffon Vulture to Bulgaria’s Eastern Balkan Mountains

In fact, the very same day in 2021 saw two publications in the Biodiversity Data Journal that reported on re-introduction successes involving birds of prey in Bulgaria, which had gone missing for decades. The second instance was the discovery of the first nesting Saker Falcons in twenty years  

When conservation work pays off: After 20 years, the Saker Falcon breeds again in Bulgaria

Both scientific publications are part of a dynamic ‘living’ collection, titled “Restoration of species of conservation importance”, whose aim is to collate publicly available research studies reporting on the reintroduction and/or restocking of animal and plant species of conservation importance around the world. The collection was inspired by the “International Scientific Conference on Restoration of Conservation-Reliant Species and Habitats” held in Sofia, Bulgaria, in 2020.

“The restoration of species is one of the most important conservation tools in the context of constantly intensified human-driven global biodiversity loss. The reintroduction/restocking activities are related to significant research and data gathering before and during the work process, which ensures their sustainable success,”

explain the collection editors.

Striking new snake species discovered in Paraguay

Only known from three individuals, Phalotris shawnella is endemic to the Cerrado forests of the department of San Pedro in east Paraguay.

Distribution map.

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.”

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.

Eleven new to science species of rain frogs are described by two scientists from the Museum of Zoology of the Pontifical Catholic University of Ecuador in the open-access journal ZooKeys. Discovered in the Ecuadorian Andes, the species are characterized in detail on the basis of genetic, morphological, bioacoustic, and ecological features.

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.

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.
