Pseudofoenus darwini is a small (4-6mm), reddish-brown species variously marked with black, with all metasomal segments banded with white on the hind borders. The mesonotum surface is strigate to strigate-punctate. Females have the first two hind tarsal segments asymmetrically produced apically to the outer side, with each being tipped there with a spine. For Tasmanian species, the latter character also occurs in P. spinitarsis, though this species can be distinguished by their larger size (7-11mm) and the mesonotum being only sparsely punctate. As with all Tasmanian Pseuodofoenus species, females can be identified by the 14-segmented antennae, and males by the 13-segmented antennae.
