Description.

Holotype, female, body length 5.9 mm, fore wing length 5.0 mm, antenna 8.0 mm.

Head. Antenna with 47 segments, 1.4 times longer than body; third segment 1.1 times fourth; middle segments 2.8 times longer than wide (7:2.5); penultimate antennal segment 0.9 times apical segment; apical segment with spine; width of face slightly less than length of face and clypeus combined (18:19); malar space 0.7 times as long as mandible width (5:7); basal width of mandible 0.8 times as long as hypoclypeal depression (7:9); malar suture absent; distance between tentorial pits 3.0 times distance between pits and eyes (9:3; Fig. 68); in dorsal view height of eye 3.2 times as high as temple (16:5); in lateral view width of eye 2.5 times as long as temple (10:4; Fig. 65); ocelli rather small and in high triangle, POL:Od:OOL = 4:5.5 (Fig. 67); distance between front and hind ocelli 0.8 times OOL (4:5); face rugose-punctate; frons, vertex and temple smooth.

Mesosoma. Length of mesosoma 1.35 times longer than high (69:51); pronotal side mainly crenulate medially, granulate ventrally; precoxal sulcus wide and punctate-crenulate (Fig. 66); mesopleuron smooth dorsally and punctate ventrally, punctures merged into mesosternum; scutellum smooth; mesopleuron smooth, rugose anteriorly; notauli deep, crenulate; mesoscutum with sparse fine punctures; scutellar sulcus 0.7 times as long as scutellum (6:9); propodeum mainly rugose laterally and its medial areola crenulate.

Wings. Fore wing: pterostigma 4.7 times as long as wide (42:9); r:2-SR:3-SR:SR1 = 9:15:29:44; vein r arising before middle of pterostigma; 1-CU1:cu-a:2-CU1:3-CU1 = 4:7:27:5; ventral length of second submarginal cell 3.4 times its apical width (41:12). Hind wing: vein M+CU:1-M:1r-m = 31:26:23 (Fig. 70).

Legs. Hind coxa shiny with sparse fine punctures; length of hind femur:tibia:basitarsus:tarsus = 55:74:38:89; length of hind femur, tibia and basitarsus 5.5, 9.25 and 9.5 times as long as their width, respectively; inner hind tibial spur 0.24 times as long as basitarsus (9:38).

Metasoma. First tergite subequal to apical width; medial length of second tergite 1.6 times third (30:19; Fig. 7); second suture crenulate; second tergite with parallel striation; third-fifth tergites mainly rugose medially; sixth tergite with curved fine striation mixed with granulation; ovipositor sheath 0.5 times as long as hind basitarsus (18:38; Fig. 69).

Colour. Yellow; antennal segments brown with medial pale band; palpi pale yellow; stemmaticum black; occipital carina brown; propleuron, mesopleuron anteriorly, precoxal sulcus, notauli, mesonotum laterally, side of scutellum and axilla black; propodeum black, but pale yelllow medially; fore and middle legs yellow, except middle femur subapically and tarsus darker than tibia; hind coxa blackish brown, except yellow dorso-basally; hind trochantellus, most part of hind femur and hind tarsus brown; hind tibia dirty yellow; wings dirty subhyaline with pterostigma and veins brown, except veins 3-SR, SR1, 3-M and r-m yellow; first-fifth metasomal tergites black, yellow laterally and at posterior corners; sixth tergite entirely black.

Male.

Unknown.

Variation.

Length of first metasomal tergite 1.0-1.2 times as long as apical width; medial length of metasomal second tergite 1.6-1.7 times as long as third tergite medially; body length 5.1-6.2 mm; fore wing length 4.0-5.1 mm.

Etymology.

From ‘vitta’ (Latin for 'ribbon, band’), because of the pale band of the antennal segments.
