A Bhutanese Herpetographer
A 21st-century man, born on a pile of dust, grew up hungry most of his childhood; walked barefoot to schools that provided food that was not enough for his small stomach; slept on jute sacks, fed on maize and potatoes, drank water directly from the streams and rivers. In love with wilderness for animals and plants. Unconditional love for Bhutan. A true son of Palden Drukpa gone incognito!

Etymology:
The specific epithet is a patronym, named in recognition of Mr. Jigme Tshelthrim Wangyal, a Forest Officer with the Department of Forest and Park Services, Ministry of Agriculture and Forests, Government of Bhutan. Jigme is an accomplished Bhutanese herpetologist and has published many papers on the subject (Wangyal, 2011, 2013, 2014; Wangyal & Gurung, 2012, 2017; Wangyal & Das, 2014; Wangyal et al., 2020). Jigme’s extensive network of Forest Officers, researchers and wildlife enthusiasts have supplemented his extensive personal observations in several of his publications, and as a consequence, many of the species currently on Bhutan’s amphibian and reptile checklist were first documented in the country through his efforts. He continues to support and inspire interest in amphibian and reptile research through seminars and field training workshops and is a vocal proponent for improving standards of herpetological research in Bhutan.
Suggested common name: Wangyal’s torrent frog.
CONCLUSIONS
In summary, we identified four species of Amolops from Bhutan: (1) Amolops sp. 1. (viridimaculatus group: from Tshewang & Letro, 2018), (2) A. cf. gerbillus (marmoratus group), (3) A. cf. putaoensis (monticola group), and (4) A. wangyali sp. nov. (viridimaculatus group). Outside of the new species described herein, we were unable to determine species identities for these taxa given the available data. Until such time as vouchered specimens are clearly identified from the country by means of a detailed morphological comparison of vouchered specimens with relevant taxonomic literature, and/or with the aid of DNA sequence data, the following nine species must be formally removed from the amphibian checklist of Bhutan: (1) Amolops formosus, (2) A. gerbillus, (3) A. himalayanus (including A. aff. himalayanus), (4) A. mantzorum, (5) A. marmoratus, (6) A. monticola, (7) A. wenshanensis, (8) Sylvirana cf. guentheri, (9) Hyla annectans (including Hyla cf. annectans). Unintentional misidentifications in the literature can result in significantly overestimated/ erroneous geographic distributions for species, a situation which undermines conservation efforts. Inaccuracies in such assessments could even result in the redirection of conservation resources (funds and efforts) away from vulnerable range restricted species that require urgent attention. For these reasons, we encourage authors not to assign species names to taxa in publications if there is any uncertainty regarding the identification of the species. Many populations of amphibians reported from Bhutan (and elsewhere in Asia) are provided non-specific locality details (e.g. lack GPS coordinates, elevation details), are not represented in museum/university collections by vouchered specimens, and are often published without photographic evidence. Locally abundant species can often be dismissed as “common”, or of little scientific interest, and subsequently ignored by researchers; however, studies on Himalayan amphibians have demonstrated that “common” or widespread species occasionally represent complexes of morphologically similar species (e.g. Dubois, 1975; Kamei et al., 2009; Dever et al., 2012; Khatiwada et al., 2017; Mahony et al., 2013, 2018, 2020), so careful attention to document every species should be made when possible. Our review of Amolops reports in literature demonstrate that some taxonomic information can be obtained from good quality images of uncollected animals, but inevitably an accurate species inventory for Bhutan’s amphibian fauna will not be possible without permanently maintained reference collections of vouchered specimens. Range restricted species may be only one drought, forest fire or hydroelectric dam away from extinction, thus the urgency to catalogue the Himalayan biodiversity has never been more urgent.

NO ONE HAS IT ALL - Simple reasons to remain humble!
Tshering Dema, unstable, sleeps on the jute sacks and stays in a shack but in her hands are twin handsome boys she gave birth to some weeks ago.
Sonam Yangdey, living in a posh house, drives posh cars, went to the best hospital in town for ante-natal care but see her crying for she has another miscarriage.
Kuenzang Choden, beautiful, good job, good house, good husband yet her pillow suffers every night with wetness of her tears, because she is yet to conceive.
Life is deep, who can understand it?
Tshelthrim Wangyal, lives with his parents, his father is a poor carpenter, he goes to school on foot every morning with empty stomach, yet he is exceptionally brilliant.
Tshewang Rinzin, a son of a wealthy politician, goes to school, with escorts and assorted food and drinks, yet he cannot assimilate what he is being taught.
Tashi Dorji, son of a medical doctor, crippled, he cannot help himself, his father cannot help him yet he treats others and they get healed.
What is in this life itself?
We all have it in bits, that is the irony of life. So why the bitterness, the envy, the anger, let's learn to manage our bit and see how we can make it better.
Rinchen Dema, virgin, focused, intelligent, but she was raped on her way to school, she became pregnant, and life was on hold for a moment. Life! Life!! Life!!!

THE AMPHIBIANS OF BHUTAN
This book: “The Amphibians of Bhutan” is all about the frogs, toads, salamander, and the obscure and enigmatic caecilians that occur in Bhutan. Of the more than 8,000 species of amphibians currently known worldwide, only 80 anurans, a single species of salamander (Caudata), and at least two undescribed caecilians (Gymnophiona) are recorded in Bhutan. This number is likely far less than accurate since there have been no serious attempts to document this group of animals by researchers or institutions, due to the fact that these moist-skinned animals, who use both land and water to complete their life cycle, do not attract funds for researchers and institutions to generate serious research. Species presented in this primer are thus through the interest of a few of us devoted, like-minded individuals who believe that these animals are extremely important to the life-support system for the Earth to survive.
This work is a result of the collection of information through an online group on the amphibians and reptiles of Bhutan created to educate the public about these neglected groups of animals. I wish to encourage more individuals to value and conserve these diverse and useful creatures. This book is not intended to replace formal batrachology courses nor is it designed for academic purposes. The goal of this book is to strengthen and facilitate connections between amphibians and the people who have a genuine or even a casual interest about the natural history of these interesting animals. And while this book touches on some academic aspects, it intentionally is more conceptual than statistical. For the average reader, common names have been provided while scientists and researchers must look at this work as something in between the core and the casual science. There are several new country records and a few undescribed and unknown species documented for the country (for further work), otherwise, nothing herein is ecologically or biologically new except for those few which are undescribed and unknown. I also freely admit that I have used all the information made available from all forms of media and from many individual citizen scientists and field foresters. In writing this manuscript, I have consulted numerous experts and sought their advice making the MS more than peer reviewed. But we humans all make mistakes – so, if you notice any, please do let me know. Being an amateur, it is even more susceptible to error. Therefore, I would like to suggest to my readers to view my primer less as a book and more as a resource that has its own style and character.
I did not initially think of writing a book; I thought of writing handouts that people can use and share to spread the word about amphibians being incredibly awesome. As such, you will see some vital facts repeated across the various topics, a combination of formal and casual fundamentals, and possibly other characters that might be considered mistakes in other settings.
I hope that book enthusiasts can take this work for what it is and not find its weaknesses too off-putting. This primer may benefit many interested English-speaking readers but I must confess that the examples and photographs are mostly those from Bhutan, not just to do justice to the title of the book but because I am one of those rare Bhutanese who takes batrachology very seriously. Consequently, the species in this primer are those that I am most familiar with, and as a result, not all the amphibian species occurring in Bhutan are covered. Hopefully, readers in other areas of the world can infer from the context which information may be applicable to their regions. Where an amphibian that is endemic to Bhutan appears as an example, there is likely a species which fills a similar ecological niche in your region, and a nominal amount of research should tell how the lesson might apply to your locality.
I wish to restrict the use of any of this information in any way unethical. So please contact me before doing so. I will almost certainly grant permission, provided you are using this material for educational purposes and public awareness and not for any political or commercial mileage. I have tried to be simple and straightforward, but this book does cover biological subject matter, and occasionally being exposed to unfamiliar scientific terms is a part of learning about the natural world. There is a glossary of herpetological terms available for you to refer to at the end of the book. I sincerely hope you enjoy my work!
Before concluding, I wish to make mention about our only endemic amphibian, the Bhutan Cat-eyed Toad, Scutiger bhutanensis. We have an obligation to investigate this species which was described at the turn of the century by scientists from Europe because we were not confident enough about its exact population or even its distribution. It is time that we take the future of these amphibians seriously and protect them using relevant research, funds and legislations. Otherwise, Bhutan might lose some species even before they have been described. It wasn’t too long ago that the endangered Gharial (Gavialis gangeticus) was extirpated from the Manas River in southern Bhutan. Let’s not allow history to repeat itself and let’s do our best to protect all animals, small or large that live in Bhutan. We must allow their survival so that our future generations may enjoy them as well. Happy reading!

A Guide to the Reptiles of Bhutan
Our intention in writing this book is to trigger an interest in the subject - the science of reptile biology. “Herps”, as the group, along with amphibians, is popularly referred to, are thought to be sensitive to changes in the environment. Understanding their ecology and conservation problems can help us understand threats we face, such as climate change. These animals are also useful for agriculture and other industries, as they are predators of insect and rodent pests that damage the crops, and for disease control through their feeding on insects, snails, and others.
Bhutan, a small kingdom in the eastern Himalayas is home to diverse flora and fauna. Conservation in Bhutan is currently focused on significant (here implying larger or economically useful) plant and animal species. Consequently, the tiger, snow leopard, elephant, and red panda, receive great attention, while snakes, lizards, tortoises, and turtles do not have conservation priority even if endemic or endangered. This book thus is an attempt to create awareness about this neglected group of animals. This book covers 82 species of snakes (out of ca. 102 species), 39 lizards and six turtles, a tortoise, and a crocodile. King cobras, Walnut kukri, Pythons, and almost all turtles and a tortoise are under the threatened category of the International Union for Conservation of Nature. Endemics of the country include the Bhutan Skink (Eutropis quadratilobus) and the Bhutan Agama (Calotes bhutanensis), both known only from the original descriptions. The species lost from the country’s fauna in the wild is the Gharial (Gavialus gangeticus). We have made an effort to limit the use of technical words, unless unavoidable. Common names and current scientific names have been mentioned. Range countries have been mentioned, and locations within Bhutan, if known, are specified.
Sizes
The sizes given are the maximum body length recorded for the particular species. For turtles and tortoises, it is the straight carapace length (CL) while for the lizards and snakes, the snout to vent length (SVL), and for crocodilians, total body length (TL).
