Adapted from Wood 1982, p. 555-556, genus name correction in Wood and Bright 1992, p. 419


The genus Stenoclyptus can be distinguished from the similar genus Pseudothysanoes Blackman by the bisulcate, almost flat and vertical declivity.


Species in this genus range from 1.0 to 1.5 mm in length and are approximately 2.5 times as long as wide. Their color ranges from brown to black. The pronotum is wider than long and asperate on its anterior half. The anterior margin of the compound eye is sinuate. The scutellum is small. The declivity is almost vertical and bisulcate, with light colored setae, and is unarmed. The scape is shorter than the 6-segmented funicle and has long setae. The oval club is small and has two straight sutures. The procoxae are separated.
