Identification of species in genus Perga

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

• Antennae 5 or 6-segmented with club

• Antennae shorter than distance between eyes

• Hind lobes of scutellum very short, not reaching hind margin

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

To view iNaturalist Research Grade observations of a particular Perga species, click on the name of that species in the list below. (Species without a link have no RG observations at this time).
