Clypeus broader than long, with shallower and denser rounded punctures ( Fig. 10b ); vertex, frons and gena with deeper and denser rounded punctures ( Fig. 10c ); scutum and scutellum with rounded, dense punctures, size of punctures as same as that on vertex ( Fig. 10e ); disc of T1–T5 with smaller and denser rounded punctures ( Fig. 10f ); mandible widened apically, with 5 teeth ( Fig. 10d ); subantennal suture directed toward outer margin of antennal socket, distinctly arcuate outward ( Fig. 10b ); fore wing ( Fig. 10g ) with the same structural features as that of P. yanruae ; pronotal lobe lamellate; omaulus rounded; axilla rounded posterolaterally ( Fig. 10e ); scutellum posterior margin rounded ( Fig. 10e ); propodeum without basal series of pits and without fovea behind spiracle; basal margin of T1 with carina; pygidial plate absent ( Fig. 10f ); tarsal claw with inner median tooth, arolium absent. Clypeus yellow, with two black longitudinal belt-shaped markings, paraocular area maculated up to top of eye ( Fig. 10b ); basal 2/3 part of mandible yellow ( Fig. 10d ); vertex black, with two yellow broad beltshaped markings, and the genal marking very narrow, separated from the marking on vertex ( Fig. 10c ); frons black, without yellow spot ( Fig. 10b ); supraclypeal area black ( Fig. 10b ); pronotal lobe black; scutum black, apical margin without markings, only with small marking along the lateral margin of scutum at the middle level of tegula ( Fig. 10e ), tegula black ( Fig. 10e ); axilla black, with a sub-round yellow marking ( Fig. 10e ); scutellum black, with two rectangle-shaped markings apicolaterally ( Fig. 10e ); metasomal tergum black, T1–T5 with two yellow bands respectively, and the bands on T1–T2 obviously narrower and longer than others ( Fig. 10f ); except fore femur, middle femur and hind femur yellow apically, out surface of fore tibia and middle tibia yellow, fore tarsus and middle tarsus yellowish brown, other parts of all legs black ( Fig. 10a ). Pubescence sparse; apical margin of clypeus, periphery of antennal socket covered paler white hairs ( Fig. 10b ); vertex, scutum and scutellum covered with sparse yellowish-brown hairs ( Fig. 10a ); episternum covered sparse white hairs ( Fig. 10c ); coxa, trochanter, femur, out surface of middle basitarsus and hind basitarsus covered white hairs, inner surfaces of middle basitarsus and inner surface of hind basitarsus covered yellowish-brown hairs; S2–S5 with denser, longer yellowish-white hairs forming scopa ( Fig. 10a ).
