Dolichogenidea wangi Liu & Chen , sp. nov.
( Figs 65 View FIGURE 65 , 69 View FIGURE 69. 61–75 )
Description. Holotype. Female. Body length 2.3 mm, fore wing length 2.9 mm.
Head. Transverse in dorsal view, 2.0× as wide as long, 0.9× as wide as mesoscutum ( Fig. 65g View FIGURE 65 ). Temple shiny with dispersed, small punctures, strongly constricted behind eyes from dorsal view. Face ( Fig. 65d View FIGURE 65 ) transverse, 0.8× as high as wide, shiny, smooth with hairy punctures, inner margins of eyes subparallel, distinctly tumescent medially. Ocelli small, posterior tangent to anterior ocellus touching posterior pair of ocelli, distance between fore and a hind ocellus distinctly longer than diameter of an hind ocellus, POL:OD:OOL = 4.0:1.5:3.5. Antenna a little longer than body length, penultimate antennomere 1.5× longer than wide.
Mesosoma. Length:width:height = 38.5:28.0:28.0. Disc of mesonotum ( Fig. 65i View FIGURE 65 ) shiny, with somewhat oily lustre, sharply and densely punctate. Scutellar sulcus straight, abruptly downcurved laterally, narrow with carinae inbetween. Scutellum convex, highly shiny, scattered with several shallow punctures. Propodeum ( Fig. 65e View FIGURE 65 ) shiny, with less well-defined areolation which open at at anterior end, rugosities presented along lateral carinae of areola, three posterior fields highly shiny and nearly polished, anterio-lateral parts shiny with long silvery setae. Mesopleuron highly polished, anterior part with shallow punctures.
Legs. Hind coxa shiny, with shallow punctures. Spines on outer side of hind tibia sparse. Spurs of hind tibia subequal, 2/5 length of hind basitarsus. Basitarsus of hind leg 0.8× as long as tarsomeres 2–4.
Wings. Rather long ( Fig. 65b, c View FIGURE 65 ). Pterostigma 2.8× as long as its widest part. Vein 1-R1 1.2× longer than pterostigma, 5.4× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, nearly perpendicular to the latter, and as long as width of it, r weakly longer than 2-SR, angled at meeting, 2-M 2/3 length of 2-SR and weakly longer than 1-SR, 2-SR+M as long as 2-SR, m-cu as long as r. First discal cell of fore wing as wide as high. Second discal cell of hind wing 1.7× wider than high. Vein cu-a curved.
Metasoma. Nearly 0.9× as long as mesosoma (33.0:38.5). T1 ( Fig. 65f View FIGURE 65 ) weakly constricted towards apex, 1.3× longer than hind width, basal 1/3 indistinctly concave, polished, turned-over part quadrate, strongly rugose, hind tubercle polished. T2 strongly rugose as T1, 3.2× wider than long in middle, nearly straight apically. T3 1.6× longer than T2. Tergites posterior to T2 highly polished, shiny, and pubescent. Hypopygium as long as apex of metasoma. Ovipositor sheath 0.8× as long as length of hind basitarsus, parallel-sided. Ovipositor short, apical attenuation almost as long as the thickened, basal part.
Colour. Black ( Fig. 65a View FIGURE 65 ). Tegula black. Palpi and spurs whitish. Antenna and ovipositor sheath black. Labrum and mandible black, except apices of mandible yellowish. Legs dark brown to black, except fore leg (basal half of femur blackish), apex of mid femur, basal 1/4 of mid and hind tibia bright reddish yellow. Wing membrane hyaline, vein 1-R1, C+SC+R, pterostigma, r, 2-SR and 2-M brown, other alar veins more or less weakly brownish.
Male. Unknown.
Host. Unknown.
Material examined ( ZJUH). Holotype: ♀, Manglinxiang , Tengchong, Yunnan, China, 2009.V.23, Wang Man- man, No. 200904807.
Distribution. Oriental [ China: Yunnan].
Etymology. The species is named in honour of the collector Dr. Wang Manman.
Remarks. This species is similar to D. conpuncta Liu & Chen , sp. nov., but differs in the following: T1 quadrate (the latter distinctly transverse); spines on outer side of hind tibia few (the latter numerous); and temple strongly constricted behind eyes from dorsal view (the latter not constricted).
