Type species

Bostrichus politus Say

Adapted from Wood 1982, p. 745-746


Xyloterinus is distinguished from other genera with a divided eye by the broad and slightly procurved basal area of the club. They are distinguished from Polygraphus Erichson, which are usually black, and Trypondendron Stephens, which usually have light and dark lines on the elytra, by their uniform brown coloration.


This monotypic genus ranges from 3.3 to 3.7 mm in length and is approximately 2.7 times as long as wide. Its color is a uniform brown. The pronotum is basically as long as wide and armed on the anterior half by asperities and two denticles on the center of the anterior margin. The scutellum is small. The declivity is convex and slightly flattened with a vestiture consisting of long hair-like setae, which is shorter on the elytra. The eye is completely divided in two parts. The scape is longer than its 4-segmented funicle. The club is unmarked by sutures and is near-circular, with its basal area broad and slightly procurved, and the rest covered by a short pubescence. The procoxae are contiguous.
