description: Dolichogenidea transcarinata Liu & Chen, sp. nov.
(Figs 61, 69)
Description. Holotype. Female. Body length 2.3 mm, fore wing length 2.7 mm.
Head. Transverse in dorsal view, 2.1× as wide as long, weakly narrower than mesoscutum (Fig. 61h). Temple shiny with shallow punctures, weakly constricted. Face (Fig. 61d) transverse, 0.7× as high as wide, rough with indistinct punctuation, inner margins of eyes nearly parallel. Posterior tangent to anterior ocellus virtually touching posterior pair of ocelli, distance between fore and a hind ocellus slightly shorter diameter of an hind ocellus, POL: OD:OOL = 3.0:2.0:4.0, a black line extending from middle ocellus to occiput. Antenna (Fig. 61j) as long as body, penultimate antennomere 1.2× longer than wide.
Mesosoma. Length:width:height = 38.0:26.5:29.0. Disc of mesonotum (Fig. 61f) shiny, finely punctate, denser on imaginary notaulic courses. Scutellar sulcus slightly curved, broad with carinae inbetween. Scutellum shallowly punctate, interspaces shiny and larger than diameter of punctures. Propodeum (Fig. 61e) shiny, with well-defined areolation which closed at anterior end and with several transversal carinae inside, costulae well-defined, lateralposterior fields polished and smooth, anterio-lateral parts a little shiny with shallow hairy punctures. Mesopleuron highly polished, strongly and densely punctate on anterior parts.
Legs. Hind coxa shiny, almost polished without punctures. Spines on outer side of hind tibia long and relatively dense. Spurs of hind tibia equal in length, nearly half length of hind basitarsus. Basitarsus of hind leg distinctly shorter than tarsomeres 2–4 (15.0:17.5).
Wings. Pterostigma large, 2.6× as long as its widest part (Fig. 61b). Vein 1-R1 1.3× longer than pterostigma, 5.4× as long as its distance from apex of marginal cell. Vein r arising from apical part of pterostigma, slightly oblique outwards, 0.8× as long as width of pterostigma, r as long as 2-SR, distinctly angled at meeting, 2-M half length of 2-SR and as long as 1-SR and weakly shorter than 2-SR+M, m-cu almost as long r. First discal cell of fore wing 1.2× wider than high. Second discal cell of hind wing 1.8× wider than high. Vein cu-a weakly curved inward (Fig. 61c).
Metasoma. 1.3× as long as mesosoma. T1 (Fig. 61g) indistinctly widened towards apex, 1.2× longer than hind width, basal 1/3 concave and nearly polished, turned-over part transverse, strongly rugose, with short longitudinal striae on hind corners. T2 strongly rugose as T1, 3.7× wider than long in middle, strongly curved apically. T3 1.4× as long as T2. Tergites posterior to T2 highly polished, shiny, and pubescent. Hypopygium distinctly shorter than apex of metasoma. Ovipositor sheath (Fig. 61i) missing, ovipositor thin, long, curved, without apical attenuation.
Colour. Reddish brown, T1–2 darker (Fig. 61a, g). Tegula yellowish brown. Palpi and spurs whitish yellow. Antenna light yellowish brown. Labrum and mandible bright yellow. Legs yellow, fore and mid coxae yellow, hind coxa reddish brown. Wing membrane hyaline, vein 1-R1, C+SC+R, pterostigma, r, 2-SR and 2-M whitish yellow, other alar veins almost colourless, pterostigma with whitish basal spot.
Variation. Body length 2.0– 2.3 mm, fore wing length 2.4–2.7 mm.
Male. Unknown.
Host. Unknown.
Material examined (ZJUH). Holotype: ♀, Mt. Westtianmu, Zhejiang, 1983.IX.10–12, Xu Zhihong, No. 833785. Paratype: 1♀, Mt. Westtianmu, Zhejiang, 1983.IX.10–12, Xu Zhihong, No. 833792 (metasoma missing).
Distribution. Oriental [China: Zhejiang].
Etymology. The specific name “ transcarinata ” derived from the Latin “trans” and “carinatus”, referring to several transversal carinae inside the areola on propodeum.
Remarks. This species is similar to D. altithoracica Liu & Chen, sp. nov. but differs in the following: head rather transverse in dorsal view (the latter less transverse); ovipositor much longer than the latter; and T3 1.4× as long as T2 (the latter 0.8× as long as T2).
