Rh

This species is well differentiated by its large subquadrate head, coloration and antennal characters; the sunken ridge extending anteriorly from the extremely short and broadly subangulate metasternum is narrow and sublaminiform, the four basal joints of the hind tarsi equal.

Readily distinguishable by its smaller size, very much smaller head and retracted tempora.
