Type material.

Holotype, ♀ (RMNH), Aga. 251a, "S. Vietnam: Dak Lak, Cu M’Gar, Ea Pok [forest], 10.vi.2005, K. Long". Paratypes (9 ♀ + 14 ♂): 2 ♀ + 6 ♂ (IEBR, RMNH), same data as holotype; 4 ♀ + 8 ♂, (RMNH, IEBR), "S. Vietnam: Ban Me Thuat, park, 9.vi.2005, K.D. Long"; 2 ♀ (RMNH, IEBR), Aga. 250a and Aga. 251b, "S. Vietnam: Pleicu, Dac Do, 800 m, bushes, 8.vi.2005, K.D. Long"; 1 ♀ (IEBR), Aga. 223, "S. Vietnam: Tay Ninh, Lo Go-Xa Mat N.P., 4.x.2003, K.D. Long".

Diagnosis.

The new species resembles Zelodia dravida (Bhat & Gupta), but the latter differs by having the head, hind leg and metasoma black, the scutellum sparsely punctate, the second submarginal cell of fore wing triangular, the wing membrane subhyaline and the pterostigma entirely brown.

Description.

Holotype, ♀, length of body 7.2 mm, of fore wing 7.4 mm.

Head.

Antennal segments 43, length of third segment 1.1 times fourth segment, length of third, fourth and penultimate segments 2.5, 2.3 and 2.0 times their width, respectively; penultimate segment as long as apical segment; antenna densely setose; scapus nearly cylindrical, twice as long as wide; length of maxillary palp 0.9 times height of head; malar space 1.3 times as long as basal width of mandible; in dorsal view length of eye 3.4 times as long as temple (Figs 453, 454); lateral ocelli large, POL:OD:OOL = 5:4:5; face punctate, but rugose-punctate medially; frons shiny, smooth, without lateral carinae; vertex sparsely finely punctate; pair of crests between antennal sockets strong, convergent; occipital flange rather large, its ventral margin convex (Fig. 447).

Mesosoma.

Length of mesosoma 1.4 times its height; subpronope medium, shallow; side of pronotum smooth with sparse fine punctures posteriorly; area near lateral carina of mesoscutum smooth; mesoscutum with distinct punctures; middle lobe of mesoscutum slightly grooved; notauli narrow, rather deep and crenulate, fused posteriorly, forming a wide shallow groove (Fig. 448); scutellar sulcus 0.8 times as long as dorsal part of scutellum; scutellum rugose-punctate; subposterior crest curved (Fig. 448); precoxal sulcus wide and shallow, largely crenulate (Fig. 447); mesopleuron below as above precoxal sulcus with distinct fine punctures; upper side of metapleuron rugose-punctate, lower side with strong rugosity; propodeum shiny with areola, without basal medial carina (Fig. 448); propodeal spiracle elongate, 2.5 times as long as wide; distance between spiracle and lateral carina 1.4 times as long as width of spiracle.

Wings.

Fore wing: second submarginal cell narrowed anteriorly and r-m angled (Fig. 450); r:3-SR:SR1 = 5:3:72; 2-SR:3-SR:r-m = 13:3:12. Hind wing: M+CU 0.7 times as long as 1-M (30:45); surroundings of cu-a sparsely setose.

Legs.

Length of hind femur, tibia and basitarsus 3.3, 5.3 and 7.5 times their width, respectively; outer side of hind coxa punctate; hind femur (as remainder of legs) with long and dense setosity (Fig. 451); outer side of apex of hind tibia with two equal pegs; length of outer and inner spurs of middle tibia 0.5 and 0.9 times middle basitarsus, respectively; length of outer and inner spurs of hind tibia 0.3 and 0.4 times hind basitarsus.

Metasoma.

First tergite twice as long as its apical width (Fig. 449); second tergite 0.7 times as long as wide apically, second suture developed (Fig. 449); ovipositor sheath 0.3 times as long as hind basitarsus.

Colour.

Yellow; antenna (except yellow scapus) dark brown; membrane of fore wing yellowish and wing without stigmal spot; parastigma and apex of vein C+SC+R of fore wing dark brown; hind tarsus light brown.

Variation.

Antennal segments 44-45; apical antennal segment 1.2-1.3 times as long as penultimate segment; length of malar space 1.3-1.6 times basal width of ma ndible; length of first tergite 1.7-2.0 times as long as its apical width; second tergite 0.7-0.8 times as long as wide apically; hind tarsus blackish brown to light brown.

Distribution.

NE Vietnam: Bac Kan and S Vietnam: Ban Me Thuat, Dak Lak, Pleicu, Tay Ninh.

Biology.

Unknown.

Etymology.

From “flavus” (Latin for “yellow”), and “stigma” (Greek for “mark”), because of the entirely yellow pterostigma.
