Diagnosis | Diagnosis (genus): Rhinophis can be distinguished from all other amniotes by the characters given for the family, and from other uropeltids by united oculars, nasals separated by rostral or barely in contact, no temporal, no mental groove, dorsal scales in 15-19 rows at midbody, Oberhäutchen dentitions that are < 1.7 mm and < 50% of the total cell size for all species examined thusfar (R. saffragamus, R. sanguineus, R. travancoricus, R. drummondhayi, R. blythii, R. philippinus, R. oxyrhynchus, and R. homolepis; Gower 2003), and shortened, dorsally compressed tail that exhibits a distinct, rugose, keratinous disc at the end, clearly separated from the surrounding ventral and dorsal scales, for which the degree of enlargement and rugosity varies among species and ontogenetically, and more anterior junction of systemic arches (mean of –3.37% SVL) compared to other uropeltid genera (mean of –1.52%) (Pyron et al. 2016: 479).

Distribution: The type locality of Typhlops oxyrhynchus SCHNEIDER 1801 was said to be “India orientali" but the species is not in India fide Mohapatra et al. 2024 (ZSI checklist). Key: Cyriac et al. 2020 and Sampaio et al. 2020 provide keys to the Indian species of Rhinophis. |
