This species can be recognized by the following combination of characters: horizontal area of propodeal dorsal face (Fig. 21) with a few sparse punctures, oblique area impunctate and without submarginal carina, posteriorly with a few short longitudinal striae connecting transverse carina; S1 (Fig. 19) anteriorly with some irregular pits, medially with sparse minute punctures; pygidium (Fig. 20) with a medial longitudinal carina; inner face of hind basitarsus medially with longitudinal groove. Description. Female (Fig. 16). Body length 12.1 mm, forewing length 8.1 mm. Color. Body almost black, with pale brown setae; mandible, tegula, pterostigma, veins and legs dark brown; posterior half of pygidium (Fig. 20) brown; wings (Fig. 16) infuscate. Head. Mandible (Fig. 17) without distinct medial transverse groove and preapical denticle, atmost with obsolete intermittent impressed line; clypeus (Fig. 17) basally with dense punctures and apically impunctate, apex medially emarginated; W: OW: L: IOD=10: 4.8: 4.9: 5.9; OOD: POD: Od=10: 5.9: 3.3; AOD: WAS: IAD: CL: CAW=10: 4.6: 3.2: 6.2: 6.7; lower frons (Fig. 17) with medial longitudinal narrow groove and dense punctures, upper frons with sparse punctures; vertex (Fig. 18) with sparse punctures, interspaces smooth. Mesosoma. Pronotal anterior carina (Fig. 16) absent; anterior half of pronotum with big punctures evenly distributed, posterior half impunctate; pronotum latero-ventrally with distinct groove in middle, area above groove smooth, area below groove with dense oblique striae; mesoscutum (Fig. 16) medially with coarse and dense punctures, sparser laterally, anterior medial groove separated from notaulus; mesopleuron with dense punctures; mesoscutellum posteriorly with irregular and dense punctures; metanotum (Fig. 21) with several sparse punctures mixed with dense minute punctures; horizontal area of propodeal dorsal face (Fig. 21) with a few sparse punctures, oblique area impunctate and without submarginal carina, posteriorly with a few short longitudinal striae connecting transverse carina; propodeal areola (Fig. 21) rectangular, APWL=5.9: 4.9: 11.2, medial longitudinal carina reaching posterior 4/5 of areola; lateral surface of propodeum dorsally with dense long oblique wrinkles, ventrally impunctate; posterior surface of propodeum with dense punctures and complete medial longitudinal carina; tegula atmost slightly longer than middle width, posterior margin without transverse impressed line; second intercubital vein of forewing (Fig. 16) sinuous; fore tibia with one spur apically, mid and hind tibiae with 2 spurs apically; inner face of hind basitarsus medially with longitudinal groove. Metasoma. Anterior half of T1 (Fig. 16) with sparse shallow punctures; subposterior area of T1 close to apex and with one transverse row of punctures; S1 (Fig. 19) anteriorly with some irregular pits, medially with sparse minute punctures, and with posterolateral groove and approaching the anterior apex; T2 antero-laterally with costate transverse depression (Fig. 16), medially obsolete; T2–T4 with sparse punctures; S2–S5 with sparser punctures than T2–T4; pygidium (Fig. 20) with a medial longitudinal carina, anterior half with coarse and dense punctures, strongly reticulate, and posterior half impunctate and coriaceous. Male. Unknown. Distribution. China (Yunnan). Etymology. The specific name mediocarinata is derived from the two latin words: medius (= medial) + carinata (= carinate), referring to pygidium with a medial longitudinal carina.
