Dolichogenidea conpuncta Liu & Chen , sp. nov.
( Figs 17 View FIGURE 17 , 67 View FIGURE 67. 21–35 )
Description. Holotype. Female. Body length 2.3 mm, fore wing length 2.6 mm.
Head. Transverse in dorsal view, 1.9× as wide as long, 0.9× as wide as mesoscutum ( Fig. 17f View FIGURE 17 ). Temple shiny with coarse punctures, not constricted behind eyes from dorsal view. Face ( Fig. 17g View FIGURE 17 ) transverse, 0.8× as high as wide, shiny, smooth with hairy punctures, inner margins of eyes subparallel. 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 = 4.0:1.6:4.5. Antenna weakly longer than body length, penultimate antennomere 1.7× longer than wide.
Mesosoma. Length:width:height = 42.0:27.0:32.0. Disc of mesonotum ( Fig. 17i View FIGURE 17 ) shiny, with sharp, dense punctures which irregularly placed on posterior half. Scutellar sulcus nearly straight, narrow with dense carinae inbetween. Appearance of scutellum almost as mesonotum, densely punctate. Propodeum ( Fig. 17d View FIGURE 17 ) shiny, with welldefined pentagonal areolation which virtually closed at at anterior end, rugose-punctate medio-anteriorly, lateral carinae of areola weakly bifurcated medially, three posterior fields highly shiny and polished, anterio-lateral parts shiny with long silvery setae. Mesopleuron highly polished, anterior part with dense, large punctures.
Legs. Hind coxa shiny, with shallow punctures. Spines on outer side of hind tibia numerous. Spurs of hind tibia nearly equal in length, 2/5 length of hind basitarsus. Basitarsus of hind leg weakly shorter than tarsomeres 2–4 (14.0:15.0).
Wings. Pterostigma 2.6× as long as its widest part ( Fig. 17c View FIGURE 17 ). Vein 1-R1 1.2× longer than pterostigma, 6.3× as long as its distance from apex of marginal cell. Vein r arising from middle of pterostigma, nearly perpendicular to the latter, and weakly longer than width of it, r nearly 2.0×as long as 2-SR, distinctly angled at meeting, 2-M 3/5 length of 2-SR and a little longer than 1-SR, 2-SR+M as long as 2-SR, m-cu a little shorter than r. First discal cell of fore wing almost as wide as high. Second discal cell of hind wing 1.5× wider than high. Vein cu-a curved ( Fig. 17b View FIGURE 17 ).
Metasoma. Nearly as long as mesosoma. T1 ( Fig. 17e View FIGURE 17 ) distinctly widened towards apex, not constricted at extremity, its length as long as hind width, basal one third indistinctly concave, polished, turned-over part strongly transeverse, reticularly rugose with an indication of a median longitudinal carina. T2 strongly rugose, 4.0× wider than long in middle, nearly straight apically. T3 as long as T2. Tergites posterior to T2 polished, shiny, and sparsely pubescent. Hypopygium as long as apex of metasoma. Ovipositor sheath half length of hind basitarsus, parallel-sid- ed and with few setae. Ovipositor short, apical attenuation distinct and 1.5× longer than the thickened, basal part.
Colour. Black ( Fig. 17a View FIGURE 17 ). Tegula black. Palpi and spurs whitish. Antenna and ovipositor sheath dark brown. Labrum dark brown and mandible reddish yellow. Legs dark brown to black, except fore leg (basal femur blackish), apex of mid femur, basal third of mid and hind tibia bright reddish yellow. Wing membrane hyaline, 1-R1, C+SC+R, pterostigma, r, 2-SR and 2-M dark brown, other alar veins more or less weakly brownish.
Variation. Body length 2.1–2.3 mm, fore wing length 2.3–2.6 mm. Apical 1/3 to 2/3 of hind tibia dark brown.
Male. Unknown.
Host. Unknown.
Material examined ( ZJUH). Holotype: ♀, Jianfengling, Hainan, 2007.VI.4–7, Zeng Jie, No. 200711401. Para- type: 1♀, Mt. Guanyin, Fogang , Guangdong, 2007. IX.15–16, Xu Zaifu, No. 20071 1481.
Distribution. Oriental [ China: Guangdong, Hainan].
Etymology. The specific name “ conpuncta ” derived from the Latin “con” and “punctus”, referring to appearance of scutellum like mesonotum, densely punctate.
Remarks. This species is similar to D. hyposidrae Wilkinson , but differs in the following: T2 strongly rugose (the latter weakly rugose); T3 as long as T2 (the latter distinctly longer); and vein r of fore wing distinctly angled with 2-SR (the latter evenly rounded at meeting).
