Belligobio eristigma

Belligobio eristigma is a species of freshwater ray-finned fish belonging to the family Gobionidae, the gudgeons. This species is found in Japan. This species was first formally described in 1925 by the American ichthyologists David [Starr Jordan] and Carl Leavitt Hubbs with its type locality given as near Okayama in Japan. When Starr and Hubbs described this species they classified it in a new genus Belligobio, so this species is the type species of that genus. However, some authorities consider that this taxon is a synonym of Hemibarbus mylodon and that Belligobio is a subgenus of Hemibarbus, However, Eschmeyer's Catalog of Fishes, recognises B. eristigma as a separate valid species within the genus Belligobio.
