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.
