Abstract

A novel sisorid catfish, Pseudecheneis nagalandensis sp. nov., collected from the Tizu River, Chindwin Basin, Nagaland, northeast India is described. This new species differs from its congeners due to the presence of a long ray of pelvic fin that extends up to anal-fin origin, slender caudal peduncle and the thoracic adhesive apparatus with 13−14 transverse ridges which are separated by grooves. This is the only species of the genus Pseudecheneis currently known from Nagaland.
