Type species, monotypic: Bracon (Pseudochivinia) tobiasi Long & van Achterberg, sp. nov. Name derived from “pseudes” (Greek for false) and the generic name Chivinia because it is only superficially similar. Diagnosis . Vein r-m of fore wing absent; vein 3-SR+SR1 of fore wing nearly straight and vein 1-R1 much longer than pterostigma; end of sclerotized part of CU1a narrow; vein cu-a of fore wing interstitial; vein m-cu of fore wing 0.3 × as long as vein 1-M ( Fig. 3I ); scape short and subtruncate apically; malar suture absent; malar space long and subparallel-sided in anterior view ( Fig. 3B ); tarsal claws with rather large lobe ( Fig. 3H ); first metasomal tergite much shorter than wide apically and with crenulate medio-longitudinal depression; metasoma largely sculptured ( Fig. 3F ); setose part of ovipositor sheath about as long as first tergite ( Fig. 3G ). Notes . Despite its superficial similarity to the subgenus Chivinia Shestakov , it is not closely related to this taxon as shown by the differences in the diagnoses. Obviously, the loss of vein r-m of the fore wing occurred at least twice in the subfamily Braconinae and, therefore, we propose the new subgenus.
