Conostigmus inermis (Kieffer, 1906)
Species Comments and History. Kieffer (1906) described this species from a male specimen or specimens collected in San Mateo, California. The original description relies mostly on coloration, microsculpture and antennal characters, but specifies “kopf glänzend, fein chagriniert, ohne Längsfurche am Scheitel” (Kieffer, 1906, pg. 259), which we interpret as the absence of the preoccipital furrow. These characters are repeated for the most part in Kieffer’s later redescription of the species (1914).
The location of Kieffer’s type material is unknown, and the characters given in the original description could apply to many different species of Conostigmus . We consider Conostigmus inermis as a species inquirenda.
