Identification of species in genus Pergagrapta

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

Antennae 5 to 6 segmented
Antennae as long or shorter than distance between eyes
Hind lobes of scutellum are relatively long, reaching beyond the hind margin

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