Description
Described from a female from Yunnan. Body length 3.3 mm (Plate 9). Forewing length 2.6 mm. MS = 1.0 MOD. Head. Face with large, round, dense (0–0.5 PD), shallow punctures (Plate 10A). Scapal basin deep, smooth, glabrous (Plate 10A). Ocellar triangle isosceles. Postocellar line very weak, broadly interrupted medially (Plate 10B). Gena with distinct, oblique wrinkles. Mesosoma. Pronotum impunctate medially, with small, deep pits on anterior margin; with large, dense (0–0.5 PD) punctures laterally (Plate 10B). Mesoscutum polished, impunctate (Plate 10D); notauli indistinct but complete, impressed as fine lines, with notaulic pit oval; parapsidal lines indistinct (Plate 10D). Scutellum with two flattened, semi-elliptical foveae on anterior margin (Plate 10D); with triangular, impunctate area antero-medially (Plate 10D); with numerous fine, short, longitudinal striae on posterior margin; with deep punctures, becoming larger towards alar foveae (Plate 10D); Mesopleuron without striae between punctures (Plate 10C). Metanotum gibbous, with large, deep, areolate-reticulate punctures (Plate 10D). Propodeum with lateral margin very slightly concave before propodeal angle; propodeal angle indistinct. Tarsal claw with three teeth.
Metasoma. Oval (Plate 10E), L/W = 15/11. T-I and T-II almost impunctate. T-III with fine, scattered punctures (Plate 10E); apex of T-III with narrow (1/3 MOD), colourless semi-transparent rim, without median notch (Plate 10F).
