Diagnosis | Diagnosis: Cathetorhinus can be distinguished from all other typhlopoids by the combination of a T-II SIP and absence of preocular (fused with nasal). Small-sized (total length 183 mm), slender-bodied (length/width ratio 92) snakes with 18 scale rows throughout, 525 total middorsals, moderate tail (2.7% of total length) with 20 subcaudals (length/width ratio 2.5), and minute apical spine. Dorsal head profile bluntly rounded, lateral profile pointed with a ventral rostral keel that terminates in a blunt point, large oval rostral (0.71 head width), eye discernible as a faint eyespot, and postocular single. Coloration of head in preservative is blackish-brown, dorsum tan with lighter venter [PYRON & WALLACH 2014: 44] |
Comment | Synonymy: Cathetorhinus may belong to Rhinotyphlops (Wallach, pers. comm.). Cathetorhinus (and therefore C. melanocephalus) has been synonymized with Rhinotyphlops by ROUX-ESTÈVE 1974. Distribution: Wallach and Pauwels (2008) commented that “the provenance of this species remains unknown: it is certainly Old World, and may be from (in order of probability) Timor, Australia, Mauritius or Tenerife”; Cheke (2011) discussed an origin from Mauritius. Type species: Cathetorhinus melanocephalus DUMÉRIL & BIBRON 1844: 270 is the type species of the genus Cathetorhinus DUMÉRIL & BIBRON 1844.Cathetorhinus melanocephalus DUMÉRIL & BIBRON 1844: 270 is also the type species of the genus Ramphotyphlops DUMÉRIL & BIBRON 1844. Morphology: for morphological data in this genus see Pyron & Wallach 2014: Table 2. |
