Sphaerodactylus molei Boettger 1894: 80.
Sphaerodactylus buergeri Werner 1900: 264.
Sphaerodactylus venezuelanus Roux 1927: 254.
Sphaerodactylus boettgeri: Donoso-Barros 1968.

Type locality: Caparo, Trinidad. Distribution. Antilles, Guyana, Venezuela, Margarita Island (Venezuela), Trinidad, Tobago.

Adult males and females measure 20-28.0 mm and 20.8-27.7 mm respectively; smallest specimen 16.6 mm. Dorsal body scales strongly keeled, minute, homogeneous, 63-83 from groin-axilla. Ventrals 31-39. Scales around mid-body 65-81. Supra-nasals two; larger anterior ones separated by 1-3 small inter-nasals. Rostral deeply notched behind, filled by 1-3 small scales; median cleft short. Fourth supralabial lies below anterior half of' eye; fourth infralabial below center of eye. Subcaudal scales to three times width of supra-caudals, alternately arranged.
