Type species

Crypturgus comatus Zimmermann

Adapted from Wood 1982, p. 1146-1152


Diagnosis

Pityoborus is distinguished from similar genera by the presence in some females of circular areas with dense hair in the anterolateral areas of the pronotum and the absence of basal and laterally raised margins of the pronotum. Females can also bear long setae ornamentations on the frons.


Description

Species in this genus range in size from 1.5 to 3.2 mm and are approximately 2.5 to 2.8 times as long as wide. Their color ranges from light yellowish brown to dark reddish brown. The pronotum is wider to equally as long as wide with the anterior margin armed by 12-18 serrations and the anterior half asperate; the lateral margins are rounded. The anterolateral areas of the female are ornamented by a long dense pubescence. The declivity is convex, with a sparse vestiture consisting of hair-like setae. The metepisternum is only visible anteriorly. The female’s frons can be ornamented by long setae in dense tufts. The anterior margin of the compound eye is emarginate. The scape is usually longer than the 5-segmented funicle. The club is oval to obovate with two septate and procurved sutures that are closer to the base. The procoxae are contiguous.
