Type species

Pityophilus barbatus Blackman

Adapted from Wood 1982, p. 1140-1142


Pityotrychus is similar to Pityophthorus Eichhoff except in having the pregula more enlarged and ornamented by a few long hairs in the male or a dense tuft of hair in the female.


The species in this genus range from 1.4 to 1.8 mm in length and are approximately 2.5 times as long as wide. Their color varies from light yellowish brown to dark brown in North American species. The pronotum is approximately as long as wide. The scutellum is small. The declivity is convex to bisulcate (in the Asian species) and has granules. The vestiture consists of short hair-like setae. The metepisternum is only visible anteriorly. The anterior margin of the compound eye is emarginated. The scape is usually longer than its 5-segmented funicle. The oval club has three procurved sutures, the first two being at least partially septate. The pregula is enlarged in both sexes and is ornamented by a tuft of long setae in the females and a few long setae in the males. The procoxae are contiguous.
