Male ( Figs 20–26 ). Body length: 0.54 mm. Colour. Head yellow except occiput, and facial prominence brown, clypeus and malar space dark brown, and a dark brown stripe on occipital foramen; eyes dark red, ocelli red-brown ( Fig. 21 ). Mandible brown. Antenna brown-yellow with scape mostly pale yellow; longitudinal sensilla on each flagellar segment dark brown ( Fig. 24 ). Mesosoma yellow except pronotum, axillae and propodeum brown to dark brown, mid-lobe of mesoscutum anteromedially with a large dark brown patch; prosternum and mesopleuron dark brown ( Fig. 20 ). Wings hyaline ( Fig. 23 ). Legs mostly white, but hind coxae basally brown. Petiole brown, tergites and sternites of metasoma dark brown except apex of T7 brown-yellow ( Fig. 20 ); genitalia with basal three-fourths dark brown and apical onefourth white ( Fig. 26 ).

Head. Head slightly wider than mesosoma; frontovertex large, with two brown carinae starting from middle of vertex margin and, forming a V-shape, extending laterally to ocelli ( Fig. 21 ). Maxillary palps short, 2-segmented, and labial palps 1-segmented. Mandibles with three teeth. Antennal formula 1:1:0:6; pedicel shorter than each flagellar segment; lengths of F1–F6, 44: 50: 47: 49: 50: 52; each flagellar segment with 5–7 longitudinal sensilla ( Fig. 24 ). Mesosoma. Mid-lobe of mesoscutum mostly with longitudinal hexagonal cells or reticulation, with 2+1+2 setae; side-lobe of mesoscutum with 1 seta, axilla with 1 seta; scutellum with placoid sensilla distantly placed, closer to fore pair than to hind pair of setae, distance between fore pair of scutellar setae slightly greater than that between hind pair ( Fig. 25 ). Fore wing 2.69× as long as maximum width of wing disc; marginal fringe rather long, 0.42× as long as maximum width of disc; submarginal vein with 2 setae, anterior margin of marginal vein with 6 setae, basal cell with 1 seta; wing disc densely setose ( Fig. 23 ); stigmal vein short, and postmarginal vein absent ( Fig. 22 ). Tarsal formula 5: 5: 5. Metasoma. Metasoma 1.67× as long as mesosoma; petiole with distinct sculpture; tergites 1–7 with setae as follows: T1, 0+0; T2–T4, 2+2 each; T5, 6; T6, 4 between cercal plates; T 7, 4 in one row. Genitalia without distinct digital lobes ( Fig. 26 ). Female ( Figs 27–33 ). Detailed characters for the female are given in Huang & Polaszek (1998 : 1939). Body rather flat and narrow. Head slightly wider than mesosoma; frontovertex large, with two brown carinae starting from middle of vertex margin and, forming a V-shape, extending laterally to ocelli ( Fig. 28 ). Fore wing 2.72–2.82× as long as maximum width of wing disc, with narrow stigma, ciliation on disc unusual, consisting of scattered, very short setae with a rather large base ( Fig. 30 ). Species group placement. Not established. Host. An unidentified diaspidid ( Hemiptera : Diaspididae ) scale on bamboo. Viggiani & Ren (1987) recorded this species from a diaspidid,? Bambusaspis sp. Distribution. China (Fujian, Hainan, Guangdong).
