Type species

Pseudothysanoes drakei Blackman

Adapted from Wood 1982, p. 510-555


Pseudothysanoes can be distinguished from the similar Thysanoes LeConte by the wider than long pronotum. Also, they lack the long hair-like setae on the club.


Species in this genus range from 0.7 to 2.0 mm in length and are approximately 2.0 to 2.8 times as long as wide. Their color ranges from yellowish brown to black. The pronotum is as wide as or wider than long and asperate on its anterior half. The scutellum is small. The declivity is convex and is either unarmed or has small spines. The vestiture consists of erect, scale-like setae, is light and contrasting with their usually dark body color, and is wider apically. The anterior margin of the eye is entire. The scape is shorter than the 6-segmented funicle and has long setae. The oval to elongate club varies in size and the number of sutures ranges from none to two; these are procurved when present. The procoxae are separated.
