Description

Species in this genus range from 0.9 to 3.5 mm in length and are approximately 1.9 to 2.9 times as long as wide. Their color ranges from yellowish brown to black. The pronotum is usually as long as wide with lateral margins elevated in a raised line. The scutellum is small and flush with the elytra. The declivity is convex and unarmed, with a hair-like vestiture. The frons is sexually dimorphic; the female’s is usually ornamented by circular tufts of hair. The anterior margin of the compound eye is entire and is not subcontiguous below. The scape is longer than the 6-segmented funicle. The club is usually obovate to ovate (but it is oval on the occurring S. schwarzi), has from none to three sutures which are straight to procurved, the first being partially septate. The procoxae are separated.
