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