Van Wallach
Van Stanley Bartholomew Wallach (born 1947) is an American herpetologist and an expert on blindsnakes and on the systematics, internal anatomy, and taxonomy of snakes. He has contributed to the descriptions of at least 46 species of snakes and has conducted fieldwork on tropical snakes in the Philippines, Nicaragua, and the Democratic Republic of the Congo. For many years Wallach worked as a Curatorial Assistant at the Museum of Comparative Zoology at Harvard University in Cambridge, Massachusetts. He retired from the museum in 2012, but he continues to work on snake taxonomy. Wallach was the lead editor of the 1,227 page authoritative reference book ''Snakes of the World''. In the 2000s Wallach was one of several herpetologists who became embroiled in a dispute with Raymond Hoser, a self-published Australian herpetologist, over proper nomenclatorial acts. Hoser charged Wallach with attempting to name species that Hoser had already described in his self-published journal. Wallach' ...

Herpetology
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists and He ...

Leptotyphlops Howelli
''Leptotyphlops'' is a genus of nonvenomous blind snakes, commonly known as slender blind snakes and threadsnakes, in the family Leptotyphlopidae. The genus is endemic to and found throughout Africa. Eleven species have been moved to the genus ''Trilepida'', and other species have been moved to the genera ''Epacrophis'', ''Epictia'', ''Mitophis'', ''Myriopholis'', ''Namibiana'', '' Rena'', ''Siagonodon'', ''Tetracheilostoma'', and ''Tricheilostoma''. Description Most species of ''Leptotyphlops'' look much like shiny earthworms. They are generally black, grey, or blackish-brown and their scales give them a segmented appearance. Their common name comes from the fact that their eyes are greatly reduced almost to the point of uselessness, and hidden behind a protective head scale. The species which are called thread snakes are so named because of their very narrow, long bodies. Behavior All blind snakes including those of the genus ''Leptotyphlops'' are burrowing snakes, spending ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Letheobia Toritensis
''Letheobia'' is a genus of blind snakes in the family Typhlopidae. Wallach, Van (2005) "''Letheobia pauwelsi'', a new species of blindsnake from Gabon (Serpentes: Typhlopidae)." ''African Journal of Herpetology'' 54 (1): 85-91. Geographic range The genus is endemic to Africa. Taxonomy In 1869, the genus ''Letheobia'' was established by Edward Drinker Cope based primarily on two specimens of '' Letheobia pallida'' from Zanzibar, but later also including ''Letheobia caeca'' (originally ''Onychocephalus cæcus'' Duméril, 1856) from Gabon. Wilhelm Peters, in 1874 when describing ''Onychocephalus lumbriciformis'' from Zanzibar and in 1878 ''Typhlops unitaeniatus'' from Kenya, considered ''Letheobia'' to be a subgenus. Nonetheless, in 1881, Peters selected ''Letheobia caeca'' Duméril as the type species for the genus. In 1883, Boulenger decided that at best ''Letheobia'' was a subgenus of ''Typhlops'', and placed it as a junior synonym. Later in reconstructing ''Rhinotyphlops'' ...
