(Figs 100–110)
Type material. Holotype, ♀ (RMNH), “ S. Vietnam: Dong Nai, Cát Tiên, N.P., Bird trail, Mal [aise] trap[s] 30–35, c. 100 m, 15–20.v.2007, C. v. Achterberg & R. de Vries, RMNH’07”. Paratype: 1 ♂ (RMNH), topotypic, but Ficus trail, 9–30.iv.2007, M.P. Quy & N. T. Manh.
Diagnosis. Antenna of ♀ with approx. 28 antennomeres (Fig. 100); frons with medio-longitudinal depression (Fig. 107); pronope large (Fig. 103); notauli rather wide anteriorly (Fig. 103); rim of mesoscutum brownish near tegulae; mesosoma ventrally and posteriorly black; propodeum gradually lowered posteriorly (Fig. 102); vein 3-SR of fore wing about twice as long as vein r (Fig. 101); vein 1-R1 slightly longer than pterostigma (Fig. 101); basal area of second metasomal tergite transverse, circular and medially 0.10–0.15 × as long as wide anteriorly, entirely sculptured and hardly or not protruding medio-posteriorly (Fig. 104); second metasomal suture widened medially; fourth and fifth metasomal tergites distinctly sculptured (Figs 100, 104); setose part of ovipositor sheath approx. 0.23 × as long as fore wing (Figs 100, 105).
Description. Holotype, ♀, length of fore wing 2.0 mm, and of body 2.4 mm.
Head. Antenna with 28 antennomeres, scapus longer dorsally than ventrally, length of third antennomere 1.1 × fourth antennomere, third, fourth and penultimate antennomeres 2.2, 2.0 and 1.4 × as long as wide, respectively (Figs 106, 110); maxillary and labial palpi with 6 and 4 segments, respectively; length of maxillary palp 0.8 × height of head; temple smooth; hypostomal flange narrow; eye 2.3 × as long as temple in dorsal view; temples directly narrowed behind eyes (Fig. 108); OOL:diameter of posterior ocellus:POL = 15:9:8; vertex largely smooth, distinctly setose and shiny; frons with median groove, medially largely smooth and shiny, but flat area near antennal sockets rugose and convex part behind it remotely punctate; face remotely punctate and superficially rugose, shiny and irregularly convex (Fig. 107); clypeus truncate medially and ventral rim thin, moderately convex and smooth; hypoclypeal depression 0.4 × as wide as face, medium-sized and rather shallow; malar suture absent; length of malar space 1.5 × basal width of mandible; mandible rather flat medially and smooth, strongly narrowed and twisted apically.
Mesosoma. Length of mesosoma 1.7 × its height; pronotum anteriorly largely horizontal and with large slit-like pronope (Fig. 103); side of pronotum smooth, but with carina and micro-crenulae anteriorly (Fig. 102); mesopleuron convex, shiny and smooth; precoxal sulcus long and curved, medially with some crenulae; episternal scrobe long and linear; pleural sulcus finely crenulate; mesosternal suture deep, medium-sized and coarsely crenulate; mesosternum punctate; notauli complete but shallow posteriorly, finely crenulate anteriorly and smooth posteriorly, moderately wide (Fig. 103); mesoscutum convex, strongly shiny, and superficially punctate or punctulate, entirely conspicuously setose and medio-posteriorly with longitudinal groove plus some striae between notauli; scutellar sulcus slightly narrowed laterally and with 5 medium-sized crenulae (Fig. 103); scutellum wide, convex, conspicuously setose, largely punctate and shiny; metapleuron largely finely and densely reticulate-rugose; propodeum anteriorly convex and about as long as posterior part, moderately shiny and coarsely reticulate-rugose (Fig. 104), posteriorly with pair of anteriorly converging carinae and anterior half with medio-longitudinal carina.
Wings. Fore wing: pterostigma wide triangular (Fig. 101); second submarginal cell slightly narrowed anteriorly (Fig. 101); 1-SR much longer than wide; 1-SR+M present anteriorly; 1-R1 1.1 × longer than pterostigma; vein r emitted just before middle of pterostigma and slender; r:3-SR:SR1:2-SR = 10:22:78:27; vein SR1 nearly straight; m-cu distinctly antefurcal; 1-CU1 widened, shorter than cu-a; 1-CU1:2-CU1 = 6:49; CU1b complete; basal and subbasal cells of fore wing similarly setose as other cells. Hind wing: M+CU:1-M:1r-m = 7:12:4; basal and subbasal cells less densely setose than other cells; m-cu distinctly indicated.
Legs. Hind coxa smooth; tarsal claws medium-sized and simple (Fig. 105); length of femur, tibia and basitarsus of hind leg 3.6, 7.9 and 5.9 × as long as their maximum width; hind tibial spurs 0.30 and 0.35 × as long as basitarsus.
Metasoma. First tergite 0.8 × longer than its apical width, gradually widened apically, convex, coarsely reticulate rugose, shiny, dorsope absent, its dorsal carinae coarsely developed basally, strongly converging, posteriorly merging in sculpture (Fig. 104); first tergite laterally with deep elliptical laterope in smooth glymma (Fig. 100); second tergite and most of third tergite coarsely reticulate-rugose (including basal area), following tergites largely rugose but much less pronounced than on second tergite (Fig. 104); basal area of second tergite transverse, narrow hemicircular and medially 0.14 × as long as combined second and third tergites; second metasomal suture and antero-lateral grooves of third tergite distinct and coarsely crenulate (Fig. 104); epipleura of second and third tergites semi-transparent; ovipositor sheath subparallel-sided and apically pointed, its setose part 0.23 × as long as fore wing, 1.2 × first tergite and 1.6 × hind basitarsus; ovipositor moderately compressed and hardly widened subapically, with small subapical nodus (Fig. 100).
Colour. Yellowish brown; palpi and metasoma ventrally (except apically) white; scapus largely, pedicellus ventrally, mouthparts, clypeus, tegulae and legs (but telotarsi dark brown) pale yellowish; remainder of antenna, stemmaticum, mesosternum, metanotum, propodeum, first tergite (except latero-posteriorly), second–fifth tergites (except laterally) dark brown; pterostigma (but pale brown apically) and most veins of fore wing (except basally) brown; wing membrane subhyaline.
Male. Paratype: length of fore wing 1.8 mm and of body 2.3 mm; antenna with 25 segments; very similar to holotype, but pronotum dorsally, mesoscutum partly, scutellum, sixth and seventh tergites dark brown or brown; mesosoma 1.5 × longer than high; vein 3-SR of fore wing twice as long as vein r.
Etymology. Named after its extensively sculptured metasoma.
Distribution. Oriental: Vietnam. Collected in lowland forest at 100 m.
