Coptoborus


Type species

Coptoborus emarginatus Hopkins

Adapted from Wood 1982, p. 800-804 (catulus, pseudotenuis, cuneatus, exutus and tolimanus)


Diagnosis

Coptoborus differs from the similar Xyleborus Eichhoff in that the elytra gradually tapers on the apical third, the sutural notch can be emarginate, and they are proportionally more elongate.


Description

Species in this genus range from 1.6 to 2.7 mm in length and are approximately 2.9 to 3.4 times as long as wide. Their color ranges from yellowish brown to reddish brown. The pronotum is longer than wide and asperate in the anterior half. The scutellum is large and flush with the surface of the elytra. The declivity is gradually convex bearing granules and denticles on interstriae 1 and 3 or only granules, and it tapers towards the apex. The vestiture is restricted to the sides where it consists of hair-like setae and on the declivity where it consists of erect bristles. The anterior margin of the compound eye is emarginate. The scape is slightly longer than the 5-segmented funicle as observed in the only occurring species. The club is obliquely truncate, with only one recurved suture on its posterior face. They have a depressed pregular region. The anterior coxae are contiguous.
