Description.
Female. Length 0.7 mm. Body black with dark bluish metallic sheen (Fig. 1A View Figure 1 ). Antenna, femora, and tibiae dark brown, head in dorsal view with bronze shine at some angle. Mesosoma black. Legs with all coxae black; trochanter and their apices deep yellow, tarsal segments 1-3 yellow, fourth and fifth tarsi dark brown (Fig. 2C View Figure 2 ). Gaster black except T6-7 dark brown.
Head in frontal view 1.2 × as broad as high (385:330) (Fig. 1B View Figure 1 ), 1.9 × as broad as mesosoma, with fine reticulate sculpture, covered with sparse and short setae; frontovertex width 0.5 × head width (117:385), antenna located below the lower eye margin and separated from clypeus margin by 1.4 × height of the torulus, inner edge of eyes diverged at the lower part, malar sulcus distinct and straight, malar space 0.65 × as long as eye height (120:185), mandible bidentate. Head in dorsal view 2.1 × as broad as long (347:168), ocelli forming an obtuse angle (110°), POL 1.8 × as long as OOL (55:30), posterior edge of eye adjacent to posterior margin of head. Antenna with scape cylindrical and covered with short setae, 9 × as long as wide (260:28), pedicel 2 × as long as wide (60:30); all funicular segments longer than wide (Fig. 1C View Figure 1 ), each funicular with three rows of irregular longitudinal sensilla, F1 and F3 2 × as long as broad respectively (40:20), obviously shorter than pedicel and other segments, F4-F6 subequal in length, 1.5 × as long as broad (45:30); clava 3-segmented, 3.6 × as long as broad (145:40), longer than the combined length of F5-F6, with obscure boundaries and apically rounded, the collective length of pedicel and flagellum 1.22 × as long as head width (470:385).
Mesosoma much shorter than metasoma and reticulate sculpture larger than that on head. Pronotum 1.8 × as long as mesoscutum length (90:50) and 2.78 × as broad as long (250:90); mesoscutum 5.2 × as wide as long (260:50) (Fig. 1D View Figure 1 ), notaular lines absent, tegula large and semicircular; scutellum slightly convex and 2.2 × as wide as long (250:117), scattered with some short white setae irregularly arranged on its posterior part, axillae very small and apically separated; propodeum medially longer than 1/3 of the scutellum (40:117), with sinuated inverted U-shaped ridges (Fig. 1F View Figure 1 ). Mesotibial spur strong, 0.6 × as long as basitarsus (63:104) (Fig. 1E View Figure 1 ). Wings absent.
Gaster 1.6 × as long as broad (694:426), longer than the combined length of head and mesosoma, T1 distinctly longer than other tergites individually (250:444), occupying about two-fifths of the total length, covered with 3-4 rows of setae, T2-T6 each with a single row of setae, T7 with 2-3 rows of short setae, and with 5 long cercal bristles at each side. Paratergites absent. Hypopygium slightly extends to the apex of gaster (Fig. 1G, H View Figure 1 ).
Male. Length 0.57-0.64 mm (0.6 ± 0.042 mm, N = 5) (Fig. 2A-C View Figure 2 ), similar to female in body color and sculpture, but differs as follows. Frontovertex slightly arched (Fig. 2D View Figure 2 ); each funicular segment clearly elongated, 3 × as long as broad, with at least 2 rows of long black whorled setae (Fig. 2E View Figure 2 ); pedicel distinctly shorter than F1, 0.67 × as its length; clava 4.25 × as long as broad; the combined length of pedicel and flagellum 1.6 × as long as head width. Gaster 1.3 × as long as broad, posterior margin of each tergite straight (Fig. 2F View Figure 2 ).
