Type material. Holotype, ♀, labelled “Rog. 059” (DThU). NC Vietnam: Ha Tinh, Huong Son, Rao An, forest , 18°22’N 106°13’E 450m, 19.v.1998, sweep [net], KD Long. GoogleMaps
Description. Holotype, female, body length 5.7 mm, fore wing length 4.8 mm ( Fig. 1 View FIGURE 1 ).
Head. Antenna incomplete, with 38 flagellomeres remaining; middle flagellomeres 2.7 × longer than wide; first flagellomere 1.2 × second; width of face to length of face and clypeus combined; malar space 0.8 × as long as basal mandible width; mandible width 0.7 × as wide as hypoclypeal depression; malar suture present; distance between tentorial pits 2.75 × distance between pits and eyes; in dorsal view, head 1.6 × as wide as long medially; and height of eye 4.0 × as long as temple; in lateral view, eye 1.5 × as long as wide; width of eye × as long as temple; ocelli large, POL: OD: OOL = 3: 6: 4; distance between front and hind ocelli 0.75 × as long as OOL ( Fig. 2A View FIGURE 2 ); face rugose-punctate, with few transverse rugosities near antennal sockets ( Fig. 2B View FIGURE 2 ); frons narrow, transversely rugose anteriorly; vertex and temple coriaceous ( Fig. 2A View FIGURE 2 ).
Mesosoma. Length of mesosoma 1.4 × as long as high; pronotal side sparsely crenulate; precoxal sulcus distinct, sparsely crenulate; mesopleuron coarsely rugose anteriorly and medially, sparsely punctate dorsally, nearly coriaceous ventrally ( Fig. 2E View FIGURE 2 ); metapleuron punctate; mesoscutum finely rugose-punctate; notauli narrow, punctate, merging into rather wide depressed area posteriorly ( Fig. 2D View FIGURE 2 ); scutellar sulcus shallow, with one median carina, 0.5 × as long as scutellum; scutellum nearly smooth; propodeum with short basal carina, rugose-punctate lateroanteriorly, irregularly rugose medio-posteriorly.
Wings. Fore wing: pterostigma 3.7 × as long as wide; r: 2-SR: 3-SR: SR1 = 7: 13: 23: 40; vein r emitted from middle of pterostigma; vein cu-a oblique and straight ( Fig. 2H View FIGURE 2 ); vein 1-CU1 distinctly shorter than cu-a; 1-CU1: cu-a: 2-CU1: 3-CU1 = 5: 7: 26: 5; second submarginal cell of fore wing parallel-sided, basal length of second submarginal cell 2.75 × its width medially ( Fig. 2H View FIGURE 2 ). Hind wing: vein M+CU: 1-M: 1r-m: 2-SC+R = 20: 20: 8: 4.
Legs. Hind femur: tibia: basitarsus = 28: 34: 16; length of hind femur, tibia and basitarsus 5.6, 8.5, and 8.0 × their maximum width, respectively; hind basitarsus: tibia: second–fifth tarsal tarsomeres combined = 16: 34: 22; inner hind tibial spur 0.25 × as long as hind basitarsus.
Metasoma. First tergite as long as its apical width ( Fig. 2G View FIGURE 2 ); second tergite 2.1 × longer than third medially; ovipositor sheath 0.4 × as long as hind basitarsus; first metasomal tergite sparsely longitudinal rugose; second–third tergites with dense longitudinal rugosities ( Fig. 2G View FIGURE 2 ); fourth–sixth tergites with longitudinal rugosities; hypopygium straight ventrally in lateral view ( Fig. 2F View FIGURE 2 ).
Colour. Head yellow, except frons anteriorly and stemmaticum yellowish brown; antenna,palpi and mandible, mesonotum ( Fig. 2D View FIGURE 2 ) and propleuron yellow; mesopleuron and metapleuron light brown; metanotum and propodeum entirely brown; fore and middle legs yellow; hind leg yellow, except apical half of femur brownish yellow; fore wing veins yellow, but veins 1-M, cu-a, 1-CU1, 2-CU1 and pterostigma brownish yellow, wing membrane hyaline ( Fig. 2H View FIGURE 2 ); first metasomal tergite entirely yellow; second–third tergites largely brown, but narrowly yellow laterally; fourth–sixth tergites brown medially and largely yellow laterally ( Fig. 2G View FIGURE 2 ); ovipositor sheath and ovipositor yellow.
Male. Unknown.
Etymology. From “flavus” (Latin for yellow) and “centrum”(Latin for centre, middle), because first metasomal tergite (about centre of body in dorsal view) entirely yellow.
Host. Unknown.
Distribution. North Central Vietnam: Ha Tinh province.
