WA Museum Records and Supplements | Updated 9 years ago

Abstract: Two new species of Gloosogobius are described from the Sepik and Ramu river systems of northern Papua New Guinea. Glossogobius coatesi sp. nov. is known from 30 specimens taken at distances ranging from 380 - 435 km upstream from the sea at elevations between 25 and 125 m. It is characterized by a combination of features which include a low number of second dorsal rays (...), usually (...) anal rays, slightly thickened pelvic fins which are somewhat elongated, 27 vertebrae, and a pattern of five large dark blotches along the middle of the side. Glossogobius torrentis sp. nov. is described from over 200 specimens collected 450 to 680 km upstream at elevations between 200 and 1800 m. It is distinguished by a well developed mental frenum, low second dorsal and anal counts (19 and 17 respectively), a short, rounded and thickened pelvic fin, and black spot at the rear part of the first dorsal fin.
