Adapted from Wood 1982, p. 746-753


Diagnosis

Trypodendron is distinguished from Xyloterinus Swaine by the basal area of the club which is chitinized and procurved into a thin arrow. In addition, the elytra coloration usually consists of longitudinal dark and light stripes.


Description

Species in this genus range from 2.7 to 4.6 mm in length and are approximately 2.5 to 2.6 times as long as wide. Their color ranges from brown to black and they are often striped. The pronotum is wider than long, and its anterior margin may be armed or not. The scutellum is small. The declivity is convex, usually unarmed. The vestiture consists of sparse, fine, short hair-like setae. The eye is completely divided. The scape is longer than the 4-segmented funicle. The obovate club’s corneous basal area is strongly procurved. The procoxae are contiguous.
