Subgenus Gonatocerus View in CoL View at ENA ( Gahanopsis Ogloblin, 1946 ), syn. & stat. n.

Gahanopsis Ogloblin 1946: 286 View in CoL , 288 (as subgenus of Lymaenon ). Type species: Lymaenon (Gahanopsis) deficiens Ogloblin , by original designation.

Gahanopsis Ogloblin View in CoL : Annecke & Doutt 1961: 4 (key), 13; De Santis 1979: 363 –364 (catalog); Huber 1986: 220 (host record); Luft Albarracin et al. 2009: 8 (list, distribution in Argentina), 13 (key), 17 (illustration). Gonatocerus Nees View in CoL ( deficiens species group, without a formal synonymy of Gahanopis under Gonatocerus View in CoL ): Huber 1988: 23 –24; Yoshimoto 1990: 37, 41 (key).

Diagnosis. Pronotum entire, very short and barely visible in dorsal view; pronotal spiracle huge; mesoscutum short, much wider than long; dorsellum with posterior margin sinuate, with a small projection medially ( Figs 160 View FIGURES 158 – 161 , 169 View FIGURES 168 – 171 , 173 View FIGURES 172 – 174 ); propodeum divided medially by a longitudinal groove; funicle of female antenna 7- or 8-segmented; forewing setae as dense as in G. ( Lymaenon ) and occurring to base of marginal vein, though sometimes with a central clear area free of setae behind marginal vein; ovipositor often projecting strongly forward under mesosoma.

Gonatocerus (Gahanopsis) could be a derived offshoot of G. ( Lymaenon ) that parasitizes mainly eggs of Membracidae .

Distribution. Neotropical region.

Hosts. Aetalionidae and Membracidae .
