Abstract

A new species of natricid snakes, Trachischium apteii sp. nov. is described from the northeastern Indian State of Arunachal Pradesh. The new species differs from its congeners in the following suite of characters: dorsal scales in 15:15:15 rows, SVL 293-299mm, higher ventral count 143-150, very faint dorsal longitudinal lines, absence of yellow patch on the neck and the belly being pale yellow. Preliminary discussion on the phylogenetic position of the members of the genus Trachischium is presented. This discovery of a new snake species advocates the need for dedicated surveys to document biodiversity across Arunachal Pradesh and the neighbouring States of northeastern India.

摘要

一种新的水蛇科蛇类，特拉基希乌姆·阿普泰伊氏新种，来自印度东北部的阿鲁纳恰尔邦。该新种与同属的其他种在以下一系列特征上不同：背鳞 15-15-15 行，SVL 293-299mm，较高的腹鳞数 143-150，非常微弱的背侧纵向线，颈部和腹部没有黄色斑块，呈淡黄色。本文对特拉基希乌姆属成员的系统发育位置进行了初步讨论。这一新蛇种的发现表明，需要进行专门的调查，以记录阿鲁纳恰尔邦和印度东北部邻邦的生物多样性。
