A new species of shieldtail snake (Squamata: Uropeltidae: Uropeltis) from the Bengaluru uplands, India

Abstract

A new species of shieldtail snake, Uropeltis jerdoni, is here described based on eight specimens from Devarayana Durga and Nandi Durga that are under-researched hills near Bengaluru in southern India. The new species is a member of the Uropeltis ceylanica group that can be distinguished from related taxa as follows: a truncate and flattened caudal shield with a circumscribed concave disc; part of rostral visible from above subequal to its distance from frontal; rostral partially separating nasal scales; 17: 17: 17 dorsal scale rows; 140–148 ventral scales; 7–9 pairs of subcaudals; dark blackish-grey above, powdered with minute yellow specks, yellow lateral stripes on neck and tail; ventrolateral region with yellow mottling; venter black. This new species is currently known only from two ranges Devarayana Durga and Nandi Durga but judging by the presence of similar, adjacent massifs, is hypothesized to be present in nearby hillocks surrounding Bengaluru City.
