Description Female STANDARD RATIOS (n = 3). L: 17.7 – 22.1 mm (mean = 20.06 mm); CR: 1.13 – 1.29 (mean = 1.20); OOR: 0.62 – 0.71 (mean = 0.67); CLR: 0.41 – 0.42 (mean = 0.41); MER: 1.20 – 1.41 (mean = 1.31); OMR: 1.03 – 1.15 (mean = 1.10); FRR: 1.52 – 1.59 (mean = 1.55); MSR: 0.69 – 0.75 (mean = 0.75); TER: 1.53 – 1.81 (mean = 1.63). HEAD. Head mostly sparsely punctate with denser punctation on frontal lamina and scrobe (Fig. 15 G); frontal spatium well defined by posterior furrow, frontal fissura distinct between anterior of frontal spatium and anterior ocellus (Fig. 15 G). MESOSOMA. Dorsum of mesosoma with scapulae, anterior of mesoscutum, scutellum, metanotum and dorsomedian area of propodeum densely punctate (Fig. 23 G); disc of mesoscutum sparsely punctate to largely impunctate (Fig. 23 G); dorsolateral area of propodeum anteriorly impunctate, posteriorly densely punctate (Fig. 27 G). Mesopleuron mostly densely punctate except near anterior and posterior margins, becoming less so around mesopleural crest; upper plate of metapleuron densely punctate near upper margin, otherwise impunctate; lower plate of metapleuron densely punctate anteroventrally, becoming impunctate near upper and posterior margins; lateral panel of propodeum densely and sub contiguously punctate above lateral carina, otherwise sparsely and minutely punctate. Scutellum with median longitudinal groove, metanotum without median longitudinal carina (Fig. 27 G). Dorso-median area of propodeum without distinct tubercule medially (Fig. 27 G). METASOMA. Metasoma with strong angle between anterior and ventral faces of S 2 in lateral view (Fig. 31 G); tergites becoming more densely punctate posteriorly than anteriorly (Fig. 35 G). T 2 with basal elevation distinct (gradulus) (Fig. 35 G). WINGS. Fore wing with three submarginal cells and two recurrent veins; second recurrent vein merging with first before reaching submarginal cells. Fore wing galbrous except along the costal vein being dense setae. COLOUR AND VESTITURE. Head and mesosoma black (Figs 7 G, 11 G); metasoma with T 1 varying from entirely black to red with transverse black apical band, T 2 red anteriorly with varying amounts of black posteriorly and laterally, remaining tergites red (Figs 11 G, 23 G); S 1 black, remaining sternites more or less red with varying amounts of median black patches, particularly on S 2 (Figs 7 G, 31 G). Vestiture black on head, mesosoma and basal segments of metasoma (apical fringes of segment 2 may be red) (Figs 7 G, 11 G, 23 G, 35 G), red on apical segments of metasoma (black vestiture may be present on black patches of integument). Wings dark brown with purple reflections. Male Male as female, except head somewhat more punctate, particularly densely on frontal spatium; more or less distinct transverse carina running between ocular sinuses behind posterior margin of frontal spatium (Fig. 18 B). Disc of mesoscutum sparsely but strongly punctate (Fig. 26 B). Occiput bearing short, dense, whitish hair. Mesosoma also with fringes of short, dense, whitish pile present posterolaterally on scutellum and metanotum (Fig. 26 B), and at posterolateral corners and laterally on propodeum. STANDARD RATIOS (n = 5). L: 14 – 21.2 mm (mean = 16.9 mm); CR: 1.15 – 1.20 (mean = 1.17); OOR: 1.04 – 1.24 (mean = 1.15); CLR: 0.60 – 0.64 (mean = 0.62); MER: 1.27 – 1.40 (mean = 1.32); OMR: 0.89 – 0.99 (mean = 0.96); FRR: 1.46 – 1.81 (mean = 1.67); MSR: 0.72 – 0.80 (mean = 0.75); TER: 1.55 – 1.74 (mean = 1.62). GENITALIA. Ventral side of paramere with a few setae on the lateral side (Fig. 40 I) and dense setae on basal part, dorsal side with sparse long setae on most of its surface (Figs 39 I, 41 I); volsella and cuspis volsellaris with sparse setae on entire surfaces (Figs 40 I, 42 I); volsella bearing a few sensory cones on basal margin (Fig. 42 I), no lamella on inner margin (Fig. 39 I). External margin of paramere not angled medially (lateral side parallel), flattened apically (Figs 39 I, 40 I), volsella acute apically (Fig. 39 I); aedeagus with 10 teeth, the first two apical teeth much reduced, serrated margin straight, convex apically (Fig. 42 I).
