Adapted from Wood 1982, p. 608-636


Diagnosis

Hylocurus spp. are similar to Micracis LeConte and Micracisella Blackman. Unlike in Micracis the club is not triangular in shape. The female’s frons has circular brushes of short, yellowish hair-like setae.


Description

Species in this genus range from 1.3 to 3.2 mm in length and are from 2.3 to 2.9 times as long as wide. Their color varies from reddish brown to black. The pronotum is as long as wide, with asperities in the anterior third. The scutellum is large. The declivity is usually sexually dimorphic, with some larger tubercles in the males and ending in a point. The vestiture consists of hair-like and/or scale-like setae. The anterior margin of the compound eye is entire. The scape is shorter than the 6-segmented funicle, and it is rarely ornamented by hair. The near circular club has two bisinuate sutures. The procoxae are subcontiguous.
