Diagnosis | Diagnosis (genus): Uropeltis can be distinguished from all other amniotes by the characters given for the family, and from other uropeltids by united oculars, nasals in contact (except U. pulneyensis and some U. grandis), no temporal, no mental groove, dorsal scales in 15-19 rows at midbody, Oberhäutchen dentitions that are > 1.7 mm and 51-80% of the total cell size in all species examined thusfar (U. phipsonii, U. ellioti, and U. ceylanica; Gower 2003), and shortened, compressed tail that is either 1) rounded with keeled dorsal scales terminating in a somewhat enlarged convex cap formed by the terminal scute (Type III), 2) shortened, heavily truncated tail ending in a distinct flattened disc covered in multicarinate scales, with a terminal scute bearing multiple distinct points (Type IV), or 3) shortened, heavily truncated tail ending in a convex disc covered in multicarinate scales with a terminal scute bearing multiple distinct points (Type V; Fig. 3, Pyron et al. 2016: 488).

Comment | “BEDDOME‘s specimen, said to have come from Ganjam district, is probably incorrectly labelled as regards locality” (fide SMITH 1943). Abundance: The commonest species in the Travancore hills. Synonymy: Silybura bicatenata GÜNTHER 1864, once considered a synonym of U. ceylanicus (fide SMITH 1943), has been revalidated by GOWER et al. 2008. Silybura shorttii BEDDOME, 1863 once considered a synonym of U. ceylanicus (fide SMITH 1943) has been revalidated by GANESH et al. 2014. Type species: Uropeltis ceylanicus CUVIER 1829 is the type species of the genus Uropeltis CUVIER 1829. Phylogeny: see Sampaio et al. 2022 for a near-complete (species-level) phylogeny of the family. |
