Identification of species in genus Pseudoperga

The matrix below is designed to aid identification of species in the genus Pseudoperga, which has the following diagnostic features:

antennae 6-segmented
antennae shorter than distance between eyes
length of head behind eye same or greater than length of eye
hind lobes of scutellum normally very short, rarely projecting beyond hind margin

Click on the matrix to download a pdf version. Images from authoritative sources of selected species follow as a further aid.
