Issue
The genus Pseudotrematomus is a synonym of Trematomus, which is confirmed by a molecular study to be published (J.-C. Hureau, pers. comm. 08 Jun. 2010). The species Pseudotrematomus centronotus (Regan, 1914) is recognised as valid.

Short description
Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng): 4 - 6; Các vây lưng mềm (tổng cộng): 32-35; Tia mềm vây hậu môn: 29 - 31. Brownish with 2 or 3 large dark spots, part of spinous dorsal blackish (Ref. 11892).
Adults live on seafloor and spawns during summer (Ref. 45168). They feed primarily on errant polychaetes, with lesser amounts of amphipods, fish eggs and mollusks.
