Tetracheilostoma Carlae
The Barbados threadsnake (''Tetracheilostoma carlae'') is a species of threadsnake. It is the smallest known snake species. This member of the Leptotyphlopidae family is found on the Caribbean islands of Barbados and Anguilla. Taxonomy and etymology The Barbados threadsnake was first identified as a separate species in 2008 by S. Blair Hedges, a herpetologist from Pennsylvania State University.Dunham, Will. ''Reuters UK'' (3 August 2008). (See: ¶ 5) Hedges named the new species of snake in honor of his wife, Carla Ann Hass, a herpetologist who was part of the discovery team. Specimens already existed in reference collections in the London Natural History Museum and in a museum in California, but they had been incorrectly identified to belong to another species. At the time of publication, August 2008, ''T. carlae'' was described as the snake species with the smallest adults in the world. The first scientific specimens taken by the research team were found under rocks in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetracheilostoma Bilineatum
The two-lined blind snake (''Tetracheilostoma bilineatum'') is a harmless blind snake species endemic to Martinique in the Lesser Antilles. Distribution Though previously recorded on St. Lucia and Barbados, specimens identified to those islands were described in 2008 as separate species, '' L. breuili'' and '' L. carlae''. A specimen identified as from Guadeloupe was reported by Duméril and Bibron (1844:331), but none are known from that island. The type locality given is "Vaterland Martinique." Description It is dark brown with two yellow stripes along its sides. It was once known as the world's smallest snake, being small enough to slither through a pencil if the lead were removed. Its typical length is 11 cm (4.5 in).Reptiles: Snake a [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetracheilostoma Breuili
The St. Lucia threadsnake (''Tetracheilostoma breuili'') is a species of blind snake in the family Leptotyphlopidae. The species is native to the West Indies. Etymology The specific name, ''breuili'', is in honor of French herpetologist Michel Breuil. Beolens B, Watkins M, Grayson M (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Leptotyphlops breuili'', p. 38). Geographic range ''T. breuili'' is endemic to the Caribbean island-nation of Saint Lucia. Habitat The preferred natural habitat of ''T. breuili'' is forest, at altitudes of . Description ''T. breuili'' can reach a total length (including tail) of . It is dark brown with two yellowish lateral stripes, like the closely related '' L. bilineatus'' (Martinique) and '' L. carlae'' (Barbados). It differs from those two species by having two spots behind its head, and a dark tail. (''Leptotyphlops breuili'', new species, p. 9 + Figure 1B). Reproduction ''T. br ...

Leptotyphlops
''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 sna ...

Leptotyphlopidae
The Leptotyphlopidae (commonly called slender blind snakes or thread snakes) are a family of snakes found in North America, South America, Africa and Asia. All are fossorial and adapted to burrowing, feeding on ants and termites. Two subfamilies are recognized. Description Relatively small snakes, leptotyphlopids rarely exceed in length; only '' Trilepida macrolepis'' and ''Leptotyphlops occidentalis'' grow larger. The cranium and upper jaws are immobile and no teeth are in the upper jaw. The lower jaw consists of a much elongated quadrate bone, a tiny compound bone, and a relatively larger dentary bone. The body is cylindrical with a blunt head and a short tail. The scales are highly polished. The pheromones they produce protect them from attack by termites.''Field Guide to Snakes of Southern Africa'' - Bill Branch (Struik 1988) Among these snakes is what is believed to be the world's smallest: '' L. carlae'' ( Hedges, 2008).

Giorgio Jan
Giorgio Jan (21 December 1791 in Vienna – 8 May 1866, Milan) was an Italian taxonomist, zoologist, botanist, herpetologist, and writer. He is also known as Georg Jan or Georges Jan. Biography After having been an assistant at the University of Vienna, Jan obtained the post of professor of botany at the university of Parma as well as becoming Director of the botanical garden. At that time, the duchy of Parma was no longer under Austrian jurisdiction following the Congress of Vienna after the defeat of Napoleon at Waterloo. Giuseppe de Cristoforis died in 1837 bequeathing his collections to the town of Milan on condition that the municipality created a natural history museum whose direction had to be entrusted to Giorgio Jan, who offered his own collections. The ''Museo Civico di Storia Naturale di Milano'' was created the following year and is the oldest natural history museum of Italy. Jan immediately engaged Ferdinando Sordelli (1837–1916), artist and naturalist, who the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
