Identification

Graphisurus triangulifer is distinctive; to separate G. fasciatus from G. despectus:

G. fasciatus female

G. despectus female

G. fasciatus male

G. despectus male

Several characters in combination will separate Graphisurus fasciatus from Graphisurus despectus:

In fasciatus, the apices of the elytra are emarginate, in despectus they are truncate

In fasciatus the scutellum has a gray pubescent mark medially, while in despectus it is all-dark

The antennal scape of fasciatus has a gray pubescent band at the middle third, while in despectus the basal two-thirds of the scape is gray

In fasciatus the dark mottling of the elytra is more pronounced and in despectus the background coloration is a more even gray

The dorsal surface of the female ovipositor of fasciatus has a distinct carina, or is at least noticeably convex, while in despectus the dorsal surface of the ovipositor is flat and unridged.

Range

e. NA to MN‒TX to Panama(1)(2)
