Type material. Holotype, ♀ (NWUX), “SW. China: Yunnan, Yaoqu, Menglun, c. 540 m, 5.x.2010, 21°93’N 101°26’E, Jiangli Tan, NWUX ”. Paratype: 1 ♂ (NWUX), “SW. China: Yunnan, Yaoqu, Mengla, c. 1200 m, 28.ix.2010, 21°74’N 101°46’E, Jiangli Tan, NWUX ”.
Diagnosis. Antenna of ♀ with approx. 23 antennomeres; mesoscutum with long groove-like medio-posterior depression and anterior half of notauli smooth (Fig. 51); mesosoma dark brown; vein 3-SR of fore wing 2.2–3.0 × as long as vein r (Figs 49, 62); dorsal carinae of first tergite united basally (Figs 52, 63); basal area of second metasomal tergite transverse and medially 0.13–0.15 × as long as wide anteriorly; area behind basal area of second tergite of ♀ coarsely crenulate (Fig. 52); setose part of ovipositor sheath approx. 0.35 × as long as fore wing.
Description. Holotype, ♀, length of fore wing 2.0 mm, and of body 2.1 mm.
Head. Antenna with 23 antennomeres, scapus longer dorsally than ventrally, length of third antennomere 1.3 × fourth antennomere, third, fourth and penultimate antennomeres 3.8, 3.0 and 2.6 × as long as wide, respectively (Figs 54, 55); maxillary and labial palpi with 6 and 3 segments, respectively; length of maxillary palp equal to height of head; temple smooth; hypostomal flange narrow (Fig. 58); eye 3.6 × as long as temple in dorsal view; temples directly narrowed behind eyes; OOL:diameter of posterior ocellus:POL = 42:19:19; vertex and frons smooth and shiny, without median groove; face smooth, shiny and convex (Fig. 56); clypeus truncate medially, slightly protruding and ventral rim thin, medially punctulate and shiny; hypoclypeal depression 0.4 × as wide as face, wide and deep; malar suture absent; length of malar space 1.2 × basal width of mandible; mandible flat medially and smooth, strongly narrowed and twisted apically and ventro-basally widened (Fig. 58).
Mesosoma. Length of mesosoma 1.5 × its height; pronotum subhorizontal anteriorly, antescutal depression absent, with narrow crenulated groove and with anterior lamella medially widened (Fig. 57); side of pronotum smooth, but oblique groove finely crenulate (Fig. 50); mesopleuron convex, shiny and smooth; precoxal sulcus present submedially as finely crenulate oblique groove; episternal scrobe large and linear (Fig. 50); pleural sulcus crenulate; mesosternal suture deep and finely crenulate; notauli nearly complete, smooth and distinctly impressed, and posteriorly with medium-sized longitudinal groove in between (Fig. 51); with some setae along notauli and on middle lobe of mesoscutum, mesoscutal lobes distinctly convex, strongly shiny and smooth; scutellar sulcus distinctly crenulate (Fig. 51); scutellum wide triangular, slightly convex, smooth, setose and shiny; metapleuron largely smooth and setose; propodeum evenly convex, largely rugulose, medio-longitudinal carina long and posteriorly connected to a small areola (Fig. 51).
Wings. Fore wing: pterostigma elongate triangular (Fig. 49); 1-M straight; 1-SR longer than wide; 1-SR+M present anteriorly; 1-R1 1.7 × longer than pterostigma; vein r emitted near middle of pterostigma and slender; r:3-SR:SR1:2-SR = 9:20:98:23; vein SR1 straight; m-cu distinctly antefurcal; 1-CU1 widened, shorter than cu-a; 1-CU1:2-CU1 = 1:17; CU1b complete, medium-sized; basal and subbasal cells of fore wing similarly setose as other cells. Hind wing: M+CU:1-M:1r-m = 9:43:14; basal and subbasal cells similarly setose as other cells; m-cu absent.
Legs. Hind coxa smooth; tarsal claws rather robust and simple (Fig. 59); length of femur, tibia and basitarsus of hind leg 4.6, 11.3 and 9.0 × as long as their maximum width; hind tibial spurs 0.20 and 0.25 × as long as basitarsus.
Metasoma. First tergite 0.8 × longer than its apical width, gradually widened apically, convex, reticulate-rugulose, shiny, dorsope absent, its dorsal carinae united basally (Fig. 52); first tergite laterally with deep and round laterope in smooth glymma; second and third tergites mainly reticulate-rugulose (including basal area, but behind area crenulate, third tergite becoming granulate posteriorly) and third tergite with antero-lateral grooves (Fig. 52); basal area of second tergite transverse, narrow, reticulate-rugulose and medially approx. 0.15 × as long as wide anteriorly and 0.07 × as long as combined second and third tergites; second metasomal suture distinct medially and finely crenulate; epipleura of second–third tergites semi-transparent; fourth and fifth tergites largely finely granulate; ovipositor sheath widened apically (Fig. 53) and its apex rounded, setose part 0.33 × as long as fore wing, 2.4 × first tergite and 2.1 × hind basitarsus; ovipositor compressed and both valves subapically widened, resulting in a distinct subapical nodus (Fig. 53).
Colour. Dark brown; palpi whitish; scapus, tegulae, legs (but telotarsi infuscated) and metasoma ventrally pale yellowish; head (but stemmaticum dark brown), propleuron, pronotum anteriorly, mesopleuron antero-dorsally and apical third of metasoma yellowish brown; pterostigma and most veins of fore wing (except basally) brown (Fig. 49); wing membrane subhyaline.
Male. Length of fore wing 1.7 mm, and of body 1.6 mm; vein 1-R1 1.3 × as long as pterostigma; vein 3-SR of fore wing 3.0 × as long as vein r (Fig. 62); length of first tergite 0.8 × longer than its apical width; very similar but less sculptured than female (especially propodeum and metasoma behind second tergite: Fig. 63).
Etymology. Named after the broadened ovipositor; “latus” is Latin for “broad” and “cauda” is Latin for “tail, appendage”.
Distribution. Oriental: China (Yunnan). Collected in submontane and montane forest at 540–1200 m.
