Vertex coriaceous with punctures separate less than 2.0 × its diameter; vertex crest slightly incurved. Sides of head behind eyes converging posteriorly. Occipital carina absent. Malar line between mandible and eye present. Gena weakly coriaceous with sparse punctures; ventral area of gena coriaceous with punctures separate more than its diameter.

Mesosoma ( Figs 4e, 4f ). Dorsal pronotal area coriaceous and papillate, almost half as long as wide; lateral margin ecarinatuste, posterior margin straight; lateral pronotal area coriaceous. Mesoscutum coriaceous with shallow punctures separate 0.5–3.0 × its diameter, basal one fourth weakly coriaceous; parapsidal furrow complete. Mesoscutellum shiny; mesoscutellar pit oval; mesoscutellar groove deep and divided into two foveae by median carina. Metapectal-propodeal disc wider than long; basal half of metapostnotum with oblique rugulae, metapostnotal median carina complete, metapostnotal lateral carina absent; dorsal propodeal area imbricate, depressing near lateral marginal carina, with short longitudinal carina near transverse posterior carina; lateral marginal carina of metapectal-propodeal complex complete, transverse posterior carina of metapectal-propodeal complex almost straight; propodeal declivity coriaceous; anterior metapleural area shiny, weakly papillate, metapleural line with three pits; lateral surface of propodeum coriaceous, upper one third with irregular rugulae. Propleuron coriaceous. Lateral surface of mesopectus with large dense punctures; mesopleural dentate process present, upper mesopleural fovea and mesopleural pit developed; posterolateral area weakly coriaceous; ventral surface of mesopectus coriaceous and papillate; mesodiscrimen present.

Forewing ( Fig. 4g ). First median cell closed; Rs 2 v 2.67 × M 2 v, forming right angle; 2r-rs&Rs 2 v not arched apically.

Metasoma ( Figs 4h, 4i, 4j, 4k ). Abdominal terga shiny with tiny sparse punctures; longitudinal sulcus of second abdominal tergum extending to about half of second abdominal tergum and fovea-like basally. second abdominal sternum with longitudinal carina; posterior margin of fifth abdominal sternum with pair of tufted setae ( Fig. 4h ); posterior margin of hypopygium medially invaginated, with pair of median lobes ( Fig. 4i ). Genitalia ( Figs 4j, 4k ): paramere with apex narrow; digitus short with pointed apex, margin with long setae in ventral view; cuspis simple with margin slightly rounded ( Fig. 4j ); aedeagus bottle-shaped.

FEMALE unknown.

Type material. Holotype ♂ ( ZJUH), China, Guangxi, Daming Mountain , 23˚30ˊ30˝N, 108˚19ˊ33˝E, 13.viii.2011, Chengjin Yan, No. 20115827.

Distribution. China (Guangxi).

Etymology. The specific name “ flavipedis ” refers to the legs of this species yellow.

Comments. This species is similar to O. rufipedis Xu & He, 2006 by having first median cell of forewing closed. However, O. flavipedis sp. nov. can be distinguished by having legs yellow, POL 0.92 × AOL, mesoscutellar groove divided into two foveae by median carina and metapostnotal lateral carina absent, whereas O. rufipedis having legs distinctly orange, POL 1.11 × AOL, median carina of mesoscutum-mesoscutellar suture without median sulcus and metapostnotal lateral carina clear and about five-sixths of metapostnotum.
