description: Priopoda dorsopuncta Sheng & Sun, sp.n. (Figures 13–18, 29)
Etymology. The specific name is derived from the second tergum being closely punctate.
Material examined. Holotype: male, CHINA: Quannan, 740m, 24 May 2008, leg. Shi-Chang Li (GSFPM). Paratype: 1 male, same data as holotype (GSFPM).
Diagnosis. Face distinctly convex, yellowish brown. Flagella with white ring. Hind tarsomeres yellowish white. Frons slightly convex. Propodeum with complete and strong carinae. First tergum approximately 2.5 times as long as apical width. Terga 1 to 3 with distinct and dense punctures.
Description. Male. Body length 9.0 to 9.7 mm. Fore wing length 8.1 to 8.5 mm. Antenna length 11.0 to 11.5 mm.
Head. Face (Fig. 14) approximately 1.9 times as wide as long, upper-median portion evidently convex; coarse, with dense indistinct granular texture; upper-lateral portion, between antennal socket and inner orbit, weakly longitudinally concave. Upper margin with a small median tubercle. Clypeal suture indistinct. Clypeus approximately 2.8 to 2.9 times as wide as long, gradually convex toward apex, with distinct punctures; apical margin blunt, with long brown hairs. Mandible and cheek with fine coriaceous texture. Lower tooth of mandible approximately 2.0 times as long as upper tooth. Malar space approximately 0.33 times as long as basal width of mandible. Gena with fine coriaceous texture and distinct punctures, distance between punctures 0.2 to 1.5 times diameter of puncture; in lateral view 1.2 to 1.3 times as long as width of eye. Lateral portion of vertex (Fig. 15) with texture as that of gena, weakly concave nearby posterior ocellus; posterior-median portion with dense and fine punctures. Interocellar area small, weakly convex. Postocellar line 0.44 times as long as ocular-ocellar line. Frons slightly convex, with fine felty texture. Antenna with 46 flagellomeres, ratio of length from first to fifth flagellomeres: 7.6:5.9:5.3:5.0:4.8. Occipital carina complete and strong.
Mesosoma. With coriaceous texture. Pronotum coarse, anterior and upper-posterior portions with indistinct fine punctures. Epomia short and weak. Mesoscutum evenly convex, with even and dense punctures, distance between punctures 0.2 to 0.5 times diameter of puncture; with distinct lateral margin, posterior portion from tegula to scutellum strongly marginate. Anterior portion of notaulus weakly present. Scutoscutellar groove wide and deep.
Scutellum evenly convex, with even distinct punctures, but slightly sparser than that of mesoscutum. Postscutellum coarse, transversely roundly convex, anterior portion deeply transversely concave. Mesopleuron with distinct punctures, distance between punctures 0.3 to 1.5 times diameter of puncture (the punctures before speculum sparser). Speculum particularly large. Epicnemial carina strong, upper end reaching to half distance to subalar prominence, far distant from front margin of mesopleuron. Metapleuron evenly convex, with texture as that of mesoscutum. Anterior end of juxtacoxal carina present. Submetapleural carina complete, anterior portion evidently convex triangularly. Wings grey-brownish hyaline. Fore vein 1cu-a opposite 1/M. Areolet almost triangular, with short petiole, receiving vein 2m-cu approximately 0.8 distance from vein 2rs-m to 3rs-m. Vein 3rs-m longer than 2rs-m. Vein 2- Cu about 1.4 times as long as 2cu-a. Hind wing vein 1/cu about 1.2 to 1.9 times as long as cu-a. Legs comparatively slender. Anterior profiles of tibiae distinct spiny. Ratio of length of hind tarsomeres from first to fifth: 10.0:4.6:3.6:2.2:2.5. Claws pectinate. Propodeum (Fig. 16) with very weak and indistinct fine punctures, basalmedian portion with a deep concavity; with complete and strong carinae. Area superomedia 1.6 to 1.9 time as long as widest width, evenly convergent backwardly. Area petiolar with strong longitudinal wrinkles. Propodeal spiracle small, circular, distance to lateral longitudinal carina as long as to pleural carina.
Metasoma. First tergum approximately 2.5 times as long as apical width. Postpetiole with distinct fine punctures, distance between punctures 0.2 to 0.5 times diameter of puncture; anterior half with shallow longitudinal median concavity. Median dorsal carina absent. Dorsolateral carina complete. Spiracle small, circular, located slightly before middle of first tergum. Second tergum (Fig. 17) 0.9 times as long as apical width, with distinct and dense punctures, distance between punctures 0.2 to 1.0 times diameter of puncture, posterior margin slightly smooth narrowly. Third tergum with texture similar to that of second tergum, but punctures on posterior portion sparser than that of anterior portion. Fourth tergum with weak and indistinct punctures. Remaining terga somewhat smooth. Eighth tergum very short. Subgenital plate with one deep apical median notch (Fig. 18).
Color (Fig. 13). Black, except the following. Ventral profile of basal portion of antenna brown to darkish brown. Flagellomeres 14 partly, 15 to 21 and main portion of 22 white. Face, clypeus, mandibles except teeth, cheek, lower end of gena, front and middle coxae and trochanters yellow to yellowish brown. Tegula blackish brown. Spot between posterior ocellus and eye, front and middle legs, hind trochanters and basal ends of femora yellowish brown. Basal 0.7 of hind tibia darkish brown. Hind tarsomeres yellowish white. Tergum 3 darkish red. Terga 4 to 8 and gonosquama brown to reddish brown. Stigma and veins brownish black.
Female. Unknown.
Remarks. Similar to P. dentata Sheng & Sun, but can be distinguished from the latter by the following combination of characters: basal-median portion of propodeum deeply concave, carinae of propodeum complete and strong, hind coxae entirely black, tergum 3 darkish red, terga 4 to 8 brown to reddish brown. Priopoda dentata: basal-median portion of propodeum without concavity, carinae of propodeum weak and incomplete, hind coxae yellowish brown, dorsal profile with longitudinal black spots, tergum 3 reddish brown, terga 4 to 8 black.
