Dolichomitus lami sp. nov.
Diagnosis. Face as high as wide, with dense, moderate-sized punctures, long hairs; mandibular upper tooth shorter than lower; mesoscutum and mesopleurum with moderately dense, small punctures; epicnemial carina extending nearly to groove below subalar prominence, then turning forward to anterior margin of mesopleuron; tubercles on tergites 3–5 weak, punctate; ovipositor down-curved at tip, 5.1x hind tibia length, ventral valve with four preapical and nine apical grooves.
Description (Holotype female) ( Fig. 1 View FIGURE 1 ). Body length 27.5 mm, fore wing 19.2 mm, ovipositor 32.5 mm. Head. Antenna with 42 flagellomeres, first flagellomere 1.4x length of second; diameter of lateral ocellus equal to ocellar-ocular distance; frons polished, with sparse hairs; face as high as wide, with dense, moderate-sized punctures, long hairs; clypeus pubescent, 0.6x as high as wide, basally weakly convex, apex thin, emarginate; malar space about 0.3x basal width of mandible; upper tooth shorter than lower tooth; occipital carina complete, meeting hypostomal carina at about 0.6x basal mandible width from base of mandible; vertex and gena polished, moderately dense small punctate, pubescent.
Mesosoma. Epomia present, 0.3x as long as mandible basal width; pronotum polished, impunctate except dorsal margin and posterior corner punctate, pubescent; mesoscutum 1.5x as long as wide at anterior level of tegulae, with moderately dense, small punctures, pubescent, notauli distinctly present on anterior 0.3 of mesoscutum, nearly extending to front level of tegulae; scutellum moderately convex, pubescent, lateral carinae absent; mesopleuron with moderately dense, small punctures, pubescent, polished and impunctate posteriorly near mesopleural suture, epicnemial carina extending nearly to groove below subalar prominence, then turning forward to anterior margin of mesopleuron; metapleuron polished with moderately dense, low punctures, pubescent, submetapleural carina complete, forming anterior lobe; propodeum with dense, coarse punctures, long hairs, mediodorsal furrow moderately deeper basally than medially, above petiolar area with transverse striae; pleural area with dense, coarse punctures, long hairs, propodeal spiracle oval, about 2.0x as long as wide, not touching pleural carina. Hind leg with femur 5.5x as long as wide, length 0.6x tibia, tarsus longer than tibia, basitarsus 0.5x tarsus, 2.4x second tarsomere, fifth tarsomere slightly shorter than third. Fore wing with areolet trapezoidal, vein 2 rs-m 0.7x length of 3 rs -m; cu-a opposite Rs & M; hind wing with vein M + Cu straight, first abscissa of vein Cu 1 about 0.6x length of vein cu-a.
Metasoma. Tergites with coarse, coalescent punctures, except apical transverse smooth bands; first tergite 2.0x as long as apical width, dorsolateral carina distinct and strong from spiracle to apex, median longitudinal carina distinct on basal 0.3, weaker and forming shallow hollow posteriorly; second tergite 1.4x length of apical width, equal to first tergite, 1.1x length of third, basal oblique groove deep, extending about half length of tergite; tergites 3–5 with weak, punctate tubercles; apical transverse smooth bands on tergites 2–4 extending about 0.1x length of each tergite; ovipositor down-curved at tip, 5.1x length of hind tibia, lower valve with four preapical and nine apical grooves.
Colour. Black. Clypeus, malar, mandibles basally, ventral part of gena, tegula, mesothorax ventrally, legs (except hind coxa black, hind tibia to tarsus dull reddish to blackish) reddish brown; wings yellowish brown, pterostigma and veins black; ovipositor yellow.
Male. Unknown.
Comparison. The forward-turning epicnemial carina is a character shared with D. tuberculatus (Geoffroy) but the two species differ in numerous characters. In Gupta & Tikar's (1976) key to species, the new species would run to D. xanthopodus Gupta & Tikar but it differs in its densely, coarsely punctate propodeum, densely punctate tubercles on metasomal tergites and entirely black tergites
Etymology. This species is named in honor of Dr Truong Xuan Lam, an entomologist from IEBR, who collected the type specimen.
Distribution. Currently known only from Hoang Lien NP, Lao Cai Province ( Fig. 4 View FIGURE 4 ).
Ecological note. The single specimen was collected in montane evergreen forest.
Material examined. Holotype: Ƥ ( IEBR), Lao Cai, Hoang Lien NP, 1940 m a.s.l, 30.vii.2008, hand net, L. X. Truong leg.
