DiagnosisDiagnosis. “Typhlops stadelmani can be distinguished from all other Honduran snakes, except for the other blindsnakes (Anomalepis mexicanus, Epictia ater, E. magnamaculata, Ramphotyphlops braminus, Typhlops costaricensis, and T. tycherus), by having similarly-sized scales completely around the body and a tiny eye located beneath an ocu lar scale. Anomalepis mexicanus has 22-24 scales around the body and the prefrontal and supranasal scales not fused with each other (versus 20 scales around body and prefrontal and supranasal scales fused in T. stadelmani). The species of Epictia have 14 scales around the body and the infranasals and oculars bordering the lip line (versus 20 scales around body and infranasals and oculars separated from lip line by supralabials in T. stadelmani). Ramphotyphlops braminus has brown to black dorsal and ventral surfaces (versus pink dorsal and ventral surfaces in T. stadelmani). Typhlops costaricensis has dark brown dorsal and ventral surfaces and T. tycherus has 22 scales around the body and a dark brown dorsal surface, (versus pink dorsal and ventral surfaces and 20 scales around body and in T. stadelmani).” (McCranie 2011: 56)
