(Figs 16 –23, 112)
Diagnosis. Frons very short and narrowly dichoptic; thorax and abdomen shiny; scutum dark brown to black with narrow acrostical yellow stripe; mesopleuron pale brown; abdomen with tergites 2–4 yellow, the remaining dark brown; coxae, trochanters and tarsi brown; femora, fore and mid tibiae pale brown, hind tibia yellow; wing brown, R2+3 short, cu p lacking.
Etymology. From the Latin “ color ” (color) and “ bi ” (two), in reference to the coloration of the abdomen in which the first segment is yellow and the remaining segments brown.
Description. Holotype male. Body: 2.1 mm. Wing: 1.7 mm. Head: antenna brown inserted above middle of head; scape as long as pedicel; postpedicel ovate, short, 2.5 times longer than wide, as long as scape and pedicel combined; stylus bare, apical, 2.5 times length of antenna. Ocellar triangle not protuberant, with 1 pair of elongate ocellar setae, strongly proclinate, almost horizontal, posterior pair absent. Narrowly dichoptic; frons very short, less than half length of face. Proboscis pale brown to yellow; palpus brown bearing 1 apical and 1 median long bristle. Postcranium shiny on margins, with gray pruinescence on center, around foramen; postcranium inflated and wide on vertex; postocular setae short and scattered. Thorax: scutum shiny with some scattered pruinescence on prescutellar area, scutellum with conspicuous pruinescence, mesopleuron subshining with scattered brown pruinescence; scutum dark brown to black with shiny metallic blue in ground color and narrow yellow acrostichal stripe broadened distally, postpronotal lobe yellow, scutellum brown, mesopleuron brown. Bristles thin and elongated; acr and dc uniserial. Differentiated bristles: 1 long npl; posterior dc pair discreetly developed, little longer than anterior dc; 1 pal short; scutellum with 2 long and robust pairs, lateral pair about two-thirds length of apical pair. Wing (Fig. 112): brown; R1 short, meeting C before middle of wing; R2+3 unusually short; cell dm emitting 2 veins; M1+2 and CuA1 evanescent apically; M1+2 slightly convex; cell cu p lacking. Legs: coxae, trochanters and tarsi brown; fore and mid femora and tibiae pale brown; hind femur yellow. Differentiated bristles: mid tibia with 1D above middle, 1AV at middle and 1AV apical; mid tarsomere 1 with 1V sub-basal; hind tibia with 1D at middle; hind femur with 1A near apex. Tibiae with some elongate and thin bristles on ventral surface. Abdomen: shiny; tergite 1 pale brown, tergites 2–4 yellow, remaining dark brown; sternites 1–3 yellow, sternite 4 pale brown, apical sternites brown. Bristles brown, short, thin and scattered. Terminalia: hypandrium as long as wide with slightly concave apex (Fig. 16); epandrium short, not deeply cleft dorsally, epandrial lamellae broadly fused basally (Fig. 17); left epandrial lamella slightly shorter than right, with slender dorsoapical process (Figs 17, 19); right surstylus about as long as left, somewhat wider in basal half (Fig. 20); left surstylus simple, slightly concave on inner surface (Fig. 19); articulated distal portion of phallus simple, elongate, subequal in length to basal portion, with basal process long (Fig. 18). Female. Similar to male except tergites more gradually darkened towards apex from pale brown to brown; sternites pale brown except sternite 8 brown. Ovipositor (Figs 21–23): eighth segment very short, wider than long; tergite 8 deeply cleft medially on distal margin; tergite and sternite 8 fused to form a ring; sternite 8 with dorsolateral membranous invaginations.
