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 longer 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.

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

Pergagrapta bella Pergagrapta bicolor Pergagrapta castanea Pergagrapta condei Pergagrapta esenbeckii Pergagrapta glabra Pergagrapta gravenhorstii Pergagrapta latreilli Pergagrapta polita Pergagrapta spinolae Pergagrapta turneri

Pergagrapta bella = Pergagrapta foersteri = Pergagrapta rossi

Pergagrapta bicolor

Pergagrapta castanea

Pergagrapta latreillii = Pergagrapta dalmanni

Pergagrapta esenbeckii

Pergagrapta glabra = Pergagrapta malaisei
