Diagnosis. Antenna of ♀ with approx. 20 antennomeres ( Fig. 1 View FIGURE 1 ); basal area of second tergite smooth, transverse and 0.10 × as long as combined second and third tergites ( Fig. 5 View FIGURES 2–11 ); vein SR1 of fore wing only basally curved ( Fig. 2 View FIGURES 2–11 ); eye in dorsal view twice as long as temple, temple roundly narrowed posteriorly ( Fig. 8 View FIGURES 2–11 ); vein 1-R1 1.2 × as long as pterostigma; vein 3-SR+SR1 of fore wing only basally distinctly curved; first and second metasomal tergites black dorsally and largely longitudinally rugose, except posteriorly; second metasomal suture distinct medially and crenulate; first tergite widened posteriorly, approx. 0.8 × longer than its apical width ( Fig. 5 View FIGURES 2–11 ); scutellar sulcus finely crenulate ( Fig. 4 View FIGURES 2–11 ); vertex smooth and shiny, frons granulate ( Fig. 8 View FIGURES 2–11 ).

Description. Holotype, ♀, length of fore wing 1.7 mm, and of body 1.8 mm.

Head. Antenna with 20 antennomeres, scapus shorter dorsally than ventrally, length of third antennomere 1.2 × fourth antennomere, third, fourth and penultimate antennomeres 4.3, 3.5 and 2.5 × as long as wide, respectively ( Figs 10, 11 View FIGURES 2–11 ); maxillary and labial palpi with 6 and 4 segments, respectively; length of maxillary palp 1.1 × height of head; temple smooth; hypostomal flange narrow ( Fig. 9 View FIGURES 2–11 ); eye twice as long as temple in dorsal view; temples roundly narrowed behind eyes ( Fig. 8 View FIGURES 2–11 ); OOL:diameter of posterior ocellus:POL = 33:13:18; vertex smooth, remotely setose and shiny; frons granulate, glabrous and shiny, without median groove ( Fig. 8 View FIGURES 2–11 ); face smooth and shiny, evenly convex ( Fig. 7 View FIGURES 2–11 ); clypeus nearly truncate medially and ventral rim thin, remainder moderately convex and smooth; hypoclypeal depression 0.5 × as wide as face and deep; malar suture absent; length of malar space 1.7 × basal width of mandible; mandible weakly convex medially, strongly narrowed and twisted apically.

Mesosoma. Length of mesosoma 1.3 × its height; pronotum nearly vertical anteriorly and antescutal depression absent; side of pronotum smooth, but oblique groove crenulate anteriorly; mesopleuron convex, shiny and smooth; precoxal sulcus absent; episternal scrobe present, linear ( Fig. 1 View FIGURE 1 ); mesosternal suture rather deep and smooth; notauli complete, narrow, smooth and posteriorly shallowly impressed, and in between no groove ( Fig. 4 View FIGURES 2–11 ), but antero-medially shallowly longitudinally impressed; mesoscutum strongly shiny, smooth, only antero-laterally and near notauli with some long setae; scutellar sulcus finely crenulate ( Fig. 4 View FIGURES 2–11 ); scutellum wide, slightly convex, smooth and shiny; metapleuron largely smooth; propodeum evenly convex, smooth and shiny ( Fig. 4 View FIGURES 2–11 ).

Wings. Fore wing: pterostigma triangular ( Fig. 2 View FIGURES 2–11 ); 1-M straight; 1-SR longer than wide; 1-SR+M present anteriorly; 1-R1 1.2 × longer than pterostigma; vein r emitted slightly basad of middle of pterostigma and slender; r:3-SR+SR1:2-SR = 3:46:13; vein SR1 only basally curved and remainder straight ( Fig. 2 View FIGURES 2–11 ); vein 2-M of fore wing as long as vein 2-SR ( Fig. 2 View FIGURES 2–11 ); m-cu slightly antefurcal; 1-CU1 and cu-a widened, subequal; 1-CU1:2-CU1 = 1:10; CU1b absent; basal and subbasal cells of fore wing similarly setose as other cells. Hind wing: M+CU:1-M:1r-m = 10:18:5; all cells equally densely setose; m-cu not indicated; 2-SC+R slightly widened ( Fig. 2 View FIGURES 2–11 ).

Legs. Hind coxa smooth; tarsal claws rather robust and simple; length of femur, tibia and basitarsus of hind leg 3.4, 6.2 and 5.7 × 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, largely longitudinally rugose, shiny, dorsope absent, its dorsal carinae coarsely developed basally and protruding, strongly converging, posteriorly present ( Fig. 5 View FIGURES 2–11 ); first tergite laterally with medium-sized laterope in distinctly crenulate glymma; second and third tergites mainly longitudinally rugose, but basal area, second tergite posteriorly and apical half of third tergite smooth ( Fig. 5 View FIGURES 2–11 ); basal area of second tergite transverse, medium-sized, smooth and 0.1 × as long as combined second and third tergites; third tergite without oblique antero-lateral grooves, but with smooth areas ( Fig. 5 View FIGURES 2–11 ); second metasomal suture distinct medially and coarsely crenulate; epipleura of 2 nd– 3 rd tergites transparent ( Fig. 1 View FIGURE 1 ); remainder of metasoma smooth, except for finely crenulate transverse groove of fourth tergite; length of ovipositor sheath 0.10 × fore wing.

Colour. Black; palpi white; scapus, pedicellus, tegulae, metasoma ventrally and legs (but apex of hind basitarsus, remainder of hind tarsus and telotarsi infuscated or dark brown) pale yellowish; head (except dark brown medio-dorsal part), third and fourth antennal segments, fifth and sixth tergites brownish yellow ( Fig. 1 View FIGURE 1 ); metasoma pale brownish and whitish ventrally ( Fig. 1 View FIGURE 1 ); pterostigma and ovipositor sheath dark brown; as most veins of fore wing (except basally); wing membrane subhyaline.

Etymology. Named after its type locality in southern Vietnam.

Distribution. Vietnam. Collected in open montane forest at 1065–1700 m.
