Paratrypauchen, a new genus for Trypauchen microcephalus Bleeker, 1860, (Perciformes: Gobiidae: Amblyopinae) with a redescription of Ctenotrypauchen chinensis Steindachner, 1867, and a key to ‘Trypauchen’ group genera

A new genus, Paratrypauchen, is described for Trypauchen microcephalus. Paratrypauchen microcephalus differs from Trypauchen in having: a scaleless abdomen, pelvic fins with an emarginate interradial membrane, and three pterygiophores anterior to the first hemal spine. Due to these differences, P. microcephalus has been assigned to Ctenotrypauchen by many recent authors. However, P. microcephalus differs notably from Ctenotrypauchen in the absence of a prominent serrated frontal crest and in lacking scales on the abdomen. The new genus is compared to Ctenotrypauchen, Trypauchen and other ‘Trypauchen’ group members.
