The status of the gobioid genusParoxyurichthys

Examination of the holotype and only known specimen ofParoxyurichthys typus Bleeker, 1876, from Indonesia revealed it to have distinctions of the cephalic lateralis, post-cranial axial osteology and pigmentation diagnostic ofGobionellus oceanicus (Pallas, 1770) of the western Atlantic.Paroxyurichthys Bleeker, 1876, is a junior synonym ofGobionellus Girard, 1859. The only other species commonly referred toParoxyurichthys, Oxyurichthys laterisquamatus Weber, 1908, from New Guinea, has anterior nares medial to the oculoscapular canals of the snout. This feature is a synapomorphy of the genusStenogobius Bleeker, 1874. The new combination,Stenogobius laterisquamatus is proposed.
