Type species

Dendrocranulus tardus Schedl

Adapted from Wood 1982, p. 708-723


Diagnosis

Dendrocranulus is distinguished from other Dryocoetina with difficulty except from Dryoxylon Bright by the longer body aspect. It can be separated from Dryoxylon by its two sutured club.


Description

Species in this genus range from 1.2 to 2.7 mm in length and are elongated, approximately 2.5 to 3.0 times as long as wide. Their color ranges from yellowish brown to dark reddish brown. The pronotum is longer than wide and asperate on its anterior half. The scutellum is small. The declivity is convex to broadly excavated and unarmed, but in one species north of Mexico it is flat to concave. The vestiture consists of long and erect hair-like setae. The anterior margin of the compound eye is emarginate. The scape is usually as long as the 5-segmented funicle. The club is near circular with two procurved sutures. The procoxae are contiguous.
