A new species of blind snake, Indotyphlops (Serpentes, Typhlopidae), from the Qinghai-Xizang Plateau, China

Typhlopidae is the most species-rich and broadly distributed family of blind snakes. Due to their secretive habits, fossorial lifestyle, and conserved morphology, the taxonomy and systematics of this group remain poorly understood. Here, a new species of blind snake is described from Xizang, China, based on morphological comparisons and molecular phylogenetic analyses. The new species is genetically divergent from its closest relatives with an uncorrected CO1p-distance exceeding 18.3%. Morphologically, it can be diagnosed by a combination of the following characters: 1) large size with 265 mm total length, 2) supralabial imbrication pattern T-V, 3) midbody scales in 18 rows, 4) total middorsal scales 432, 5) subcaudals 17, 6) infralabials 2, 7) absence of a terminal tail spine, and 8) light-colored head cap. Currently, the new species is known only from Xizang, China, but it likely occurs in adjacent regions in Nepal.
