Conostigmus subinermis (Kieffer, 1907)

Species Comments and History. Johnson and Musetti (2004) listed this species as having a Holarctic distribution, but this appears to be a mistake. Kieffer (1907) described two species, subinermis and nigriceps, from female specimens collected in Italy. Dessart (1972a) later synonymized nigriceps with subinermis, but again, there is no mention of North American specimens. Dessart (1972a) notes the unique shape of the mesosoma, and mentions, “elle sera redécrite en détail dans une autre note” (pg. 28), but it appears that he never did publish another note on the species. His writing indicates that he viewed Kieffer’s type specimens, but does not mention where he viewed them (Dessart, 1972a). The location of the specimens is currently unknown, and we were not able to verify the identity of the species or confirm its presence in the Nearctic. We consider Conostigmus subinermis as only a Palearctic species at this time.
