Metriorrhynchus rhipidius, copyright Fir0002/Flagstaffotos.

Belongs within: Lycinae.

Metriorrhynchus is a genus of lycid beetles in which the prothorax, which covers the head, bears distinct areolets, and which have elytra with the subsutural costa parallel with the suture. A genus Porrostoma has historically been recognised for species in which the rostrum is rather long, thin and shining, but no clear division can be made between these and more typical species (Lea 1909).

The Queensland species M. apterus stands out for its lack of wings (Lea 1909).
