摘要

新种 Oreichthys warjaintia 描述于印度东北部梅加拉亚邦的 Pyrngang 溪（Surma-Meghna 盆地）。它与 Oreichthys 属中所有已知鱼种的区别在于它具有以下特征组合：完整的侧线，带有 25-27 片鳞片，13 条分枝胸鳍鳍条，5-5½ 条分枝臀鳍鳍条，眶下有 14 排乳突，身体横线上有 ½3/1/2½ 排鳞片，尾鳍基部有黑色斑点，以及背鳍、尾鳍和臀鳍的颜色。Oreichthys warjaintia 与线粒体 cox1 序列数据可用的所有已知 Oreichthys 种类的原始遗传距离为 8.3% 至 11.1%。

Oreichthys warjaintia, a new species of cyprinid fish from Meghalaya, India (Cypriniformes: Cyprinidae).

Oreichthys warjaintia, new species, is described from the Pyrngang stream (Surma-Meghna basin), Meghalaya, northeast India. It can be distinguished from all known species within the genus Oreichthys in having the following combination of characters: complete lateral line with 25-27 pored scales, 13 branched pectoral-fin rays, 5-5½ branched anal-fin rays, 14 rows of papillae on suborbital, ½3/1/2½ scale rows in transverse line on body, presence of a black blotch on caudal-fin base, and in the coloration of dorsal, caudal, and anal fins. Oreichthys warjaintia is distinct from all known Oreichthys species for which mitochondrial cox1 sequence data are available by a raw genetic distance ranging from 8.3% to 11.1%.

期刊介绍： The Journal of Fish Biology is a leading international journal for scientists engaged in all aspects of fishes and fisheries research, both fresh water and marine. The journal publishes high-quality papers relevant to the central theme of fish biology and aims to bring together under one cover an overall picture of the research in progress and to provide international communication among researchers in many disciplines with a common interest in the biology of fish.
