Carphoborus minimus Fabricius
Adapted from Wood 1982, p. 371-386
This species can be distinguished from the similar Polygraphus Erichson by having the anterior margin of the compound eye emarginate instead of completely divided and by the elevated alternate declivital interstriae at the basal margin.
Species in this genus range from 1.4 to 2.6 mm in length and are approximately 2.2 to 2.6 times as long as wide. Their color ranges from dark brown to black. The pronotum is wider than long. The scutellum is small and depressed. The declivity is convex with distinctively raised alternate interstriae, most noticeable in interstriae three which also has rows of pointed tubercles. The vestiture consists of short and thick scale- and hair-like setae. The frons is dimorphic; the female’s is ornamented by abundant setae, the male's with a transverse, usually bituberculate elevation near upper level of eyes and less hair-like setae. The anterior margin of the compound eye is emarginate. The scape is usually longer than the 5-segmented funicle. The club is spatulate (somewhat rhomboid) with at least two distinct straight or transverse sutures, sometimes a third is visible. The procoxae are contiguous.
