The main character given to distinguish P. brevivertex in the original description of Camras (2001) was a “short vertex”. This character is difficult to assess, however, be- cause the vertex may be tightly curved and of variable shape in the material to hand. Apically the vertex has an area which is not covered with setulae and which may have a depression, but the shape, size and extent of any depression can vary considerably, giving a different im- pression of the vertex shape. There is no other character available to distinguish P. brevivertex from P. nigrita , and therefore Physocephala [ Pseudophysocephala ] brevivertex Camras, 2001 is herewith placed as a junior synonym of Physocephala [ Pseudophysocephala ] nigrita Camras, 1962 (syn. nov.).
