Micracisella


Type species

Micracisella opacicollis LeConte

Adapted from Wood 1982, p. 594-608


Diagnosis

Species in the genus Micracisella are similar to those in Micracis LeConte, but they can be distinguished by the emarginate anterior margin of the eye, in some species so long it can be subcontiguous in the inferior margin, and also by the cylindrical shape of the scape.


Description

Species in this genus range from 1.2 to 2.5 mm in length and are approximately 3 times as long as wide. Their color varies from yellowish brown to black. The pronotum is usually longer than wide and asperate anteriorly. The scutellum is small. The declivity is convex and has hair-like setae; as in Micracis it is acuminate in its apex. The anterior margin of the compound eye is emarginate; the eye can also be very long and subcontiguous below in some species. The scape is shorter than the 6-segmented funicle and it is ornamented by a tuft of long hair. The oval club has two procurved sutures that not reach the middle. The procoxae are subcontiguous.
