摘要

Abstract Three new species of the ptereleotrid fish genus Parioglossus, P. caeruleolineatus, P. senoui and P. winterbottomi are described based on specimens from Japan, Palau and India. Parioglossus caeruleolineatus (8 specimens, 20.4-27.1 mm SL, Amami-oshima Island, Japan) differs from all other congeners in having a moderately oblique mouth at an angle of 51-58° (average 55°) to longitudinal axis of body, and a bright blue stripe running from nape to dorsum of caudal peduncle in male when fresh or alive. Parioglossus senoui (8 specimens, 17.5-22.9 mm SL, Babeldaob Island, Palau, and Iriomote-jima Island, Japan) differs from all other congeners in having three segmented pelvic-fin rays. Parioglossus winterbottomi (2 specimens, 31.0 and 37.8 mm SL, West Bengal, India) differs from all other congeners in having cheek and opercular scales, and the first dorsal fin shaped like a horse's mane in males. A revised key to the species of Parioglossus is provided.
