Pseudocyanopterus van Achterberg, Cao & Yang , gen. nov.

Figs 7 , 8

Type species: Pseudocyanopterus raddeivorus sp. nov.

Diagnosis. Scapus comparatively small (compared to pedicellus) and truncate apically ( Fig. 7E ); vein 1r-m of hind wing approx. twice as long as vein 2-SC+R; angle of vein 1-SR with vein C+SC+R approx. 80°; vein cu-a of fore wing interstitial; vein CU1b rather reclivous ( Fig. 8D ); vein SR1 3.0 × vein 3-SR; vein 2-SR of fore wing as long as vein 3-SR; marginal cell of fore wing nearly reaching wing apex; second submarginal cell parallel-sided; vein 1-SR+M of fore wing straight; vein 1-M 1.5 × as long as vein m-cu; surroundings of vein cu-a of hind wing densely setose; tarsal claws without distinct lobe; medio-basal depression of 1 st tergite deep and elongate; 2 nd tergite with antero-lateral and medio-basal areas shorter than half length of tergite and with posteriorly weakly converging and wide sublateral grooves; second suture deep and coarsely crenulate ( Fig. 7H ); maximum width of 3 rd tergite approx. 2.3 × its median length (without 2 nd metasomal suture); 3 rd and 4 th tergite with crenulate antero-lateral grooves; ovipositor narrow but apically widened and with minute teeth, its upper valve convex dorsally ( Fig. 8E ).

Runs in existing keys (e.g. Belokobylskij 2000) to Cyanopterus Haliday , but differs by having the ovipositor apically widened, vein 2-SR fore wing as long as vein 3-SR, maximum width of 3 rd tergite approx. 2.3 × its median length (without 2 nd metasomal suture; at least 2.6 × its median length in Cyanopterus ) and scapus truncate apically in lateral view.

Distribution. Palaearctic China (Liaoning), one species.

Biology. Parasitoid of Cerambycidae (Coleoptera) .

Etymology. Named after “Pseudes” (Greek for “false”) and the generic name Cyanopterus , because of its superficial similarity to Cyanopterus Haliday. Gender : masculine.
