Etymology.

The name of the new species is based on the lower portion of frons being deeply concave.

Type material.

Holotype, Female, CHINA: Matoushan National Natural Reserve, 400m, Zixi County, Jiangxi Province, 8 May 2009, leg. Mei-Juan Lou. Paratype s: 1 female, same data as holotype except 1 May 2009. 1 female, CHINA: Wuyishan National Natural Reserve, 1160m, Yanshan County, Jiangxi Province, 15 June 2009, leg. Zhi-Yu Zhong.

Description.

Female. Body length 16.0 to 18.0 mm. Fore wing length 10.5 to 11.0 mm. Ovipositor sheath length about 1.2 mm.

Head. Face approximately 1.1 times as wide as long, median portion slightly concave, with irregular wrinkles; lateral margin finely punctate; upper-lateral portion nearby antennal socket with irregular transverse wrinkles; upper margin with a small median tubercle. Clypeal suture weak. Clypeus ( Figure 2 ) approximately 1.6 times as wide as long, evenly and evidently convex; basal portion with sparse, distinct and fine punctures; apical portion almost impunctate. Mandible short, basal portion with weak and indistinct punctures and brown hairs. Cheek slightly concave, with fine coriaceous texture. Malar space 0.48 to 0.63 times as long as basal width of mandible. Gena with distinct dense punctures and long brown hairs; straightly convergent backwardly. Vertex smooth, with fine and weak punctures. Postocellar line approximately 0.8 times as long as ocular-ocellar line. Interocellar area with wrinkles and a deep median longitudinal groove. Dorsal profile of frons rough, weakly concave centrally, with irregular wrinkles; lateral portion almost smooth. Antenna with 52 to 54 flagellomeres.

Mesosoma. Pronotum ( Figure 7 ) rough, anterior portion with distinct transverse wrinkles, hind margin with oblique transverse wrinkles; upper-posterior portion with indistinct fine transverse wrinkles; lower portion with distinct reticulate wrinkles; subanterior margin with a strong longitudinal ridge ( Figure 7 ). Mesoscutum with dense, indistinct and fine punctures, hind margin with fine transverse wrinkles; nearby hind margin irregularly rough. Scutellum and postscutellum with dense wrinkles. Mesopleuron rough, upper-anterior portion with fine oblique longitudinal wrinkles; lower portion with distinct reticulate wrinkles. Without speculum, the place with oblique lines. Posterior transverse carina of mesosternum not complete, broken before middle coxa. Metapleuron evidently convex, with rough and dense reticular wrinkles. Anterior portion of submetapleural carina strongly convex, posterior portion weak and indistinct. Wing ( Figure 8 ) grey-brownish hyaline. Fore wing vein 1cu-a distal of 1/M, distance between them about 0.65 times length of 1cu-a. Vein 2-Cu approximately as long as 2cu-a. Hind wing vein cu-a strongly reclivous, 1-cu 0.6 to 0.7 times as long as cu-a. Legs comparatively slender. Hind coxa with distinct fine punctures; dorso-apical margin of first trochanter produced as a tooth. Fore and middle claws indistinctly pectinate at extreme base. Hind claws simple, strongly curved approximate at right-angle. Ratio of length of hind tarsomeres 10.0:3.7:2.0:1.0:1.7. Propodeum with dense and rough reticular wrinkles and a shallow median longitudinal concavity.

Metasoma. Hind portion from second tergum strongly compressed. Apical margin of first sternum reaching to level of spiracle. Second tergum approximately 1.25 times as long as first tergum, 1.9 times as long as third tergum. Ovipositor sheath approximately 0.5 times as long as apical depth of metasoma.

Color ( Figure 1 ). Head and mesosoma black, except the following: inner orbits, median portions of gena orbits and scape yellowish brown; apical portion of pedicel, basal half of flagellum except base of first flagellomere, coxae except black bases, trochanters and femora reddish brown; apical portion of flagellum blackish brown; fore and middle tibiae and tarsi except fifth segments, brownish yellow; basal 0.7 to 0.8 of hind tibia darkish brown; tegulae blackish brown to reddish brown; median portion of mandible and hind tarsi except fifth segment, yellow. Terga, except dorsal portion of second tergum and main portions of seventh and eighth terga brownish black, reddish brown. Stigma brown. Veins brownish black.

Variation. The specimen from Wuyishan National Natural Reserve, Yanshan County, Jiangxi Province, has the fore and middle legs almost entirely yellow.
