Diagnosis

This genus can be distinguished from all other North American Hylesinina by the emarginate anterior margin of the compound eye and the widely separated procoxae.


Description

Species in this genus range from 2.1 to 3.4 mm in length and are approximately 2.0 to 2.1 times as long as wide. The two North American species in this genus have a slight contrasting color between the pronotum and the elytra, the pronotum ranging from dark brown to reddish with yellowish to light brown elytra. The pronotum is wider than long, with the anterolateral areas armed by several asperities. The scutellum is small. The declivity is convex and has pointed tubercles. The vestiture consists of hair-like setae. The anterior margin of the compound eye is emarginate. The scape is nearly as long as the 7-segmented funicle. The club is ovate and flattened, marked by three straight sutures, the first partly septate. The procoxae are separated.
