Mesosoma. In dorsal view, pronotum significantly shorter than mesonotum, its posterior margin triangularly emarginate medially, ratio width of pronotum posteriorly to length of pronotum medially = 1.7:1; mesoscutum with two short and weak admedian line anteriorly, without notaulus, parapsidal line distinct, extending from posterior margin to three quarters of mesoscutum; scutellum and metanotum conspicuously convex medially, both tops at same height, metanotum slightly lower than scutellum; metapostnotum smooth, wide and arch-shaped in middle, narrowing towards sides into linear ( Fig. 1D ), posterior margin distinctly concave ( Fig. 1D ); ratio of length of metanotum to metapostnotum at middle = 2:1 ( Fig. 1D ); propodeum lustrous, with declivity at its posterior, about 0.38 × length of propodeum, dorsum widest at middle. ( Fig. 1D ). Wing. Forewings with three submarginal cells, SMC2 receiving crossvein 1m-cu at basal 0.63, SMC3 receiving crossvein 2m-cu at basal 0.6 ( Fig. 1E ); SMC2 on vein RS much shorter than its length on vein M ( Fig. 1E ); SMC3 strongly narrowed above and forming triangle, petiolate, petiole length 0.25–0.5 × height of SMC3; pterostigma small, ratio of its length to 2r-rs = 1:3; ratio of SMC2 to SMC3 on vein M = 1:1 ( Fig. 1E ); ratio of length of marginal cell to distance from tip of marginal cell to wing tip = 1:2; hindwing crossvein cu-a arcuate or curved, vein M and vein cu-a of hindwing coincides at intersection of vein M + CuA ( Fig. 1E ). Legs. Fore legs without tarsal comb; orbiculae ca. 0.33 × as long as tarsal claws; orbicular pecten dense and long, about 0.5 × length of tarsal claw; all tibiae, mid and hind basitarsi with long, blue-black metallic luster spines; all tarsomere 5 beneath with a median row of spines; long spur of hind tibia 0.75 × as long as basitarsus; ratio of hind tibia length to hind tibia longer spur at apex and tergum 1 = 9:5:6. Metasoma. Not petiolate, subfusiform ( Fig. 1F ); apical sternum strongly compressed laterally, with distinct longitudinal ridge ventrally ( Fig. 1G ). Male. Similar to female except as follows: body length 6.2–11 mm ; forewing length 5.5–9.2 mm ( Fig. 2A ). Scape with triangular yellowish white spot below, flagellum ventrally more or less reddish brown on at least first three segments ( Fig. 2D ); metasomal tergum 7 white, some specimens with white maculate on hind tibia dorsally, and its spur white. Base half of sterna 1–3, terga 2–4 largely with broad band of bluish-gray pubescence; hind coxa dorsally with squamiform pubescence. OOD:OD:POD:OCD= 9:4.5:11:10 ( Fig. 2C ); antenna stout and long, A5–13 obviously serrated, flagellum strongly crenulate basally, above with large shallow depression ( Fig. 2D ); vertex slightly protruding between top of eyes; LID:MID:UID = 37:46:40 ( Fig. 2B ); UID equal to length of A3 and A4 combined; length of A1 A2:A3:A4:A5:A8:A12:A13 = 10:3:8:10:10:9:7:8; ratio of length of A3 to AW of A3 =2:1; ratio of length of A13 to BW of A13 = 10:3. Ratio of width of pronotum posteriorly to length of pronotum medially = 2:1; ratio of length of metanotum to metapostnotum at middle = 4:1; propodeum with declivity at its posterior, about 0.2 × length of propodeum ( Fig. 2E ). Metasomal sternum 6 prominent in angular shape laterally, forming V shape medially. All tarsomere 5 without median row of spines ventrally. SGP and genitalia. In ventral view ( Fig. 2G ), SGP nearly truncate or slightly arched at apical margin, with dense, black setae, translucent from base to middle area; digitus strongly enlarged apically, with irregular, dense and long black setae at apex and base; paramere short, feathery, as long as digitus, with short setae at inner side, apex of aedeagus with distinct, band-like and transparent membrane, length equal to aedeagus ( Fig. 2H, I ). Comparison. The new species is similar to P. alienus ( Smith, 1879 ) in having the following characteristics: hind femur and hind tibia black; ocelli forming a right-angled triangle ( Fig. 1C ); SMC3 strongly narrowed above and forming triangle, petiolate; hindwing vein M+CuA diverging at cu-a ( Fig. 3F ); SGP nearly truncate or slightly arched at apical margin; but markedly differs by the characters given in the Table 1 . Distribution. China ( Yunnan , Hainan , Guangdong ). Etymology. The name pilisquamatus originates from the Latin word “pil”(= pubescence) and “squamatus” (= squamiform), referring to squamiform pubescence on the metasomal terga 1–3.
