Redescription. See Triapitsyn, Bezark et al. (2002) for a detailed redescription and diagnosis. Diagnosis. Gonatocerus (Cosmocomoidea) atriclavus is a member of the ater subgroup of the ater species group. It is characterized by the following unique combination: female antenna ( Fig. 196 ) with scape yellow to light brown; pedicel, F1–F3, F4 (basally) and F7 brown; F4 (distally), F5 and F6 light brown (F5–F7 distinctly lighter than other funicle segments); F8 dark brown; clava black; mps present on F2–F8; forewing ( Figs 198 , 201 ) with cubital row of setae complete, extending to base of marginal vein. Also illustrated here are dorsellum and propodeum ( Fig. 197 ) of the female, as well as antenna ( Fig. 199 ), dorsellum and propodeum ( Fig. 200 ), a pair of wings ( Fig. 201 ), and genitalia ( Fig. 202 ) of the male.

Distribution. NEOTROPICAL: Argentina, Costa Rica *, Mexico (Sinaloa and Veracruz), and Trinidad and Tobago. NEARCTIC: Mexico (Tamaulipas) ( Triapitsyn, Bezark et al. 2002).

Hosts. Homalodisca sp., Oncometopia clarior (Walker) , and an unknown species of Proconiini (Triapitsyn 2006a) , as well as Oncometopia (Similitopia) sp. ( Triapitsyn & Bernal 2009), and Tapajosa rubromarginata (Signoret) [new record] ( Cicadellidae ). This species was reared on Homalodisca vitripennis (Germar) eggs (a factitious host) under quarantine laboratory conditions in Riverside, California, USA (original material from Sinaloa, Mexico) ( Triapitsyn & Bernal 2009) until November 2008, when its colony had to be discontinued when only males emerged in the last generation.
