Biodiversity of the family Typhlopidae








Genus
Letheobia

African Gracile Blind Snakes

Grazile Blindschlangen

Slanke Ormeslanger

1869 Letheobia Cope 1868 (type species: Onychocephalus caecus Dumeril 1856)
Contents: 32 species, of which 21 (65.6%) are endemic.
Remarks: Previously included three species now placed in Afrotyphlops (decorosus, jubanus, obtusus), three other species now placed in Rhinotyphlops (ataeniatus, scorteccii, unitaeniatus), and one other species now reassigned to Typhlops (coecatus). Letheobia was formerly regarded as a synonym of Typhlops (e.g., Boulenger 1893) and, more recently, of Rhinotyphlops (e.g., Roux-Estève 1974; Hahn 1980). Formally revalidated by Broadley & Wallach (2007), although the genus had been treated as valid already in some other works (e.g., Broadley, Doria & Wigge 2003; Wallach 2005; Chirio & Ineich 2006).
Distribution: Equatorial Africa, Middle East.
Reported from: Angola, Burundi, Cameroon, Central African Republic, Congo-Brazzaville, Congo-Kinshasa, Equatorial Guinea (Rio Muni), Eritrea, Ethiopia, Gabon, Ghana, Guinea, Israel, Jordan, Kenya, Liberia, Nigeria, Rwanda, Sao Tome & Principe (Principe, Rolas Island, Sao Tome), Somalia, South Sudan, Tanzania (incl. Pemba, Zanzibar), Togo, Turkey, Uganda, Zambia, Zimbabwe.
