Dolerus possilensis

Similar to D. nitens but with minimal metallic reflections and in the female with shorter, sparser hairs on the mesopleura. The mesosternum has shallow punctures throughout. The outer hairs are recurves in their apical third. Hairs on the mesonotum and head when viewed in profile are shorter than the width of an ocellus and, for the most part, about half the width. Males are unknown.

Dolerus possilensis larvae are undescribed but presumed to feed on grasses or sedges.
