Diagnosis. This species can be recognized by the following combination of characters: mandible, apex of clypeus, antennal segments, tegula, tibiae, tarsi and posterior half of pygidium yellowish brown ( Figs 1, 2, 4, 7 ); wings ( Fig. 1 ) completely transparent; horizontal area of propodeal dorsal face ( Fig. 5 ) almost impunctate, only with several sparse punctures, oblique area densely punctate and without submarginal carina; S1 ( Fig. 6 ) with sparse minute punctures; inner face of hind basitarsus ( Fig. 4 ) medially without longitudinal groove. Description. Female ( Fig. 1 ). Body length 8.1–8.9 mm , forewing length 4.3–4.8 mm . Color. Body almost black, with short whitish setae; mandible, apex of clypeus, antennal segments, tegula, tibiae, tarsi and posterior half of pygidium yellowish brown ( Figs 1, 2, 4, 7 ); coxae and lateral margin of S1 ( Fig. 6 ) dark brown; trochanters, femora and pygidium medially brown; pterostigma and veins pale yellow; wings ( Fig.1 ) completely transparent. Head. Mandible ( Fig. 2 ) without distinct medial transverse groove and preapical denticle, atmost with obsolete intermittent impressed line; clypeus ( Fig. 2 ) basally with coarse punctures, apically impunctate, apex medially truncated; W: OW: L: IOD=10: 3.8: 5.8: 6.7; OOD: POD: Od=10: 6.8: 3.2; AOD: WAS: IAD: CL: CAW=10: 3.6: 2.6: 5.3: 5.5; lower frons ( Fig. 2 ) medially with dense punctures, laterally sparser, and mixed with some minute ones, upper frons with sparse punctures; vertex ( Fig. 3 ) with sparse punctures, interspaces smooth. Mesosoma . Pronotal anterior carina obsolete, anterior half of pronotum with sparse punctures, posterior half impunctate; pronotum latero-ventrally with distinct groove in middle, area above groove smooth, area below groove with dense oblique striae; mesoscutum medially with dense punctures, laterally sparser, anterior medial groove separated from notaulus; mesopleuron with dense minute punctures mixed with several sparse punctures; anterior half of mesoscutellum ( Fig. 1 ) with sparse punctures, posterior half with denser ones; metanotum ( Fig. 5 ) medially impunctate, laterally with dense punctures; horizontal area of propodeal dorsal face ( Fig. 5 ) almost impunctate, with several sparse punctures, oblique area densely punctate and without submarginal carina, posteriorly with short longitudinal striae connecting transverse carina; propodeal areola ( Fig. 5 ) subrectangular, weakly convergent posteriorly, APWL=4.6: 3.2: 7.2, medial longitudinal carina reaching posterior 4/5 of areola; lateral surface of propodeum dorsally with dense long oblique wrinkles, ventrally smooth; posterior surface of propodeum with dense minute punctures and ventral 3/4 with medial longitudinal groove; tegula atmost slightly longer than middle width, posterior margin without transverse impressed line; second intercubital vein of forewing slightly arched; fore and mid tibiae with one spur apically, hind tibia with 2 spurs apically; inner face of hind basitarsus ( Fig. 4 ) medially without longitudinal groove. Metasoma. Anterior half of T1 ( Fig. 1 ) almost impunctate, with several sparse shallow punctures; subposterior area of T1 close to apex and distinctly depressed, with one transverse row of shallow punctures; S1 ( Fig. 6 ) with sparse minute punctures and posterolateral groove; T2 antero-laterally with costate transverse depression ( Fig. 1 ), medially obsolete, anteriorly and medially with sparse shallow punctures, posteriorly with scattered punctures; T3–T5 ( Fig. 1 ) with small dense punctures mixed with some bigger punctures; S2–S5 with denser punctures than T3–T5; anterior half of pygidium ( Fig. 7 ) with sparse small punctures mixed with some big ones, and posterior half impunctate. Male. Unknown. Distribution. China ( Hainan ). Etymology. The specific name flavobrunnea is derived from the two latin words: flavus- (= yellow) + brunneus (= brown), referring to the characters: mandible, apex of clypeus, antennal segments, tegula, tibiae, tarsi and posterior half of pygidium yellowish brown.
