Nhi"; 2 ♀ (RMNH), Aga. 301 and Aga. 302, id., but 17.iv.2006.

Diagnosis.

The new species is close to Braunsia sumatrana Enderlein, 1906, from Indonesia and East Malaysia, but differs by having the first tergite 3.3 times (twice in Braunsia sumatrana ) as long as its apical width, basal two thirds of the third tergite longitudinally striate (only basal half) and the apical third of the third tergite micro-sculptured (smooth) and the hind coxa smooth (sparsely finely punctate).

Description.

Holotype, ♀, length of body 9.2 mm, of fore wing 7.5 mm, ovipositor 8.0 mm.

Head.

Antennal segments 47; length of third segment 1.3 times fourth segment, length of third, fourth and penultimate segments 2.5, 2.2 and 1.3 times their width, respectively; length of apical antennal segment 1.6 times as long as penultimate segment; maxillary palp 0.8 times height of head; in dorsal view length of eye 2.9 times temple (Fig. 88); POL:OD:OOL = 7:5:13; antennal sockets weakly tubular (Fig. 88); face shiny, with sparse punctures; frons and vertex shiny and smooth; occipital flange rounded, area hardly protruding (Fig. 89).

Mesosoma.

Length of mesosoma 1.4 times its height; subpronope large and deep; side of pronotum smooth; area near lateral carina of mesoscutum with crenulae; side of mesoscutum nearly smooth, with sparse fine punctures and setae; notauli wide and crenulate anteriorly, narrower and smooth posteriorly (Fig. 83); scutellar sulcus deep and with 3 carinae; scutellum slightly convex with sparse fine punctures; mesopleuron above precoxal sulcus largely smooth; mesopleuron below precoxal sulcus with sparse fine punctures; precoxal sulcus wide and shallow, slightly crenulate (Fig. 80); metapleuron with sparse fine punctures; propodeum with a strong subbasal carina (Fig. 83), without areola, largely rugose posteriorly; spiracle medium-sized, round and 1.7 times as long as wide.

Wings.

Fore wing: second submarginal cell triangular, with rather long ramellus, 0.7 times as long as vein r (11:15) (Fig. 84); r:3-SR:SR1 = 5:1:61; 2-SR:3-SR:r-m = 15:1:15; vein cu-a of fore wing distinctly antefurcal. Hind wing: vein M+CU 0.4 times as long as 1-M (24:57); surroundings of cu-a glabrous.

Legs.

Length of hind femur, tibia and basitarsus 5.4, 7.6 and 9.0 times their width, respectively; hind coxa shiny smooth; hind femur with sparse fine punctures and medium-sized setosity (Fig. 86); outer side of apical third of middle tibia with a row of 4 pegs; length of outer and inner spurs of middle tibia 0.5, and 0.6 times their basitarsus, respectively; length of outer and inner spurs of hind tibia 0.4, and 0.5 times their basitarsus.

Metasoma.

First tergite long and slightly widened apically (Fig. 85), shiny and largely smooth; length of first tergite 3.3 times its apical width; dorsal carinae of first tergite diverging and fused apically; second tergite long and nearly parallel-sided; second tergite 2.6 times longer than wide apically; second tergite and base of third tergite largely striate; third tergite micro-sculptured apically; remainder of metasoma smooth; ovipositor sheath wide, ribbon-shaped (Fig. 90), 1.3 times as long as fore wing.

Colour.

Black; malar space ivory; clypeus, palpi, mandible, fore and middle legs yellow; mesosoma reddish-yellow (but below precoxal sulcus black); first tergite basally, first and second tergite ventrally white; wing membrane somewhat infuscate (Fig. 84).

Variation.

Male with 44-45 antennal segments; length of apical antennal segment 1.4 times as long as penultimate segment; vein cu-a of fore wing slightly antefurcal; vein 3-SR vertical; vein M+CU of hind wing 0.6 times as long as 1-M; outer side of middle tibia with row of 3 or 6 pegs and cluster of 3 and 5 pegs at apex; first and second metasomal segments whitish-yellow basally.
