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 in 1974, Roux-Estève moved all of Letheobia species into Rhinotyphlops, mostly into her Groups IV, V and VI. However, molecular studies in the 2000s showed that Rhinotyphlops, as conceived by Roux-Estève (1974), was polyphyletic, and that many if not all of Groups V and VI constituted a separate genus, for which the name Letheobia had priority.[2] In 2007 Broadley and Wallach formally revived the genus Letheobia. In 2013, Pyron et al. considered with some certainty that Letheobia was a sister group to the combined genera Afrotyphlops and Megatyphlops, while the three were then sister to Rhinotyphlops, and the four were the sister to Typhlops.[3] SpeciesThe genus Letheobia contains the following 37 species which are recognized as being valid.[4]
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Letheobia. EtymologyThe specific name, pauwelsi, is in honor of Belgian herpetologist Olivier Sylvain Gérard Pauwels.[5] References1. ^1 Wallach, Van (2005) "Letheobia pauwelsi, a new species of blindsnake from Gabon (Serpentes: Typhlopidae)."
