Description Female STANDARD RATIOS (n = 1). L: 21.5 mm; CR: 1.19; OOR: 0.61; CLR: 0.41; MER: 1.27; OMR: 1.04; FRR: 2.02; MSR: 0.77; TER: 1.60. HEAD. Head mostly impunctate except on frontal lamina and scrobe; frontal spatium not well defined dorsally (Figs 16 E, 20 E); frontal fissura present from anterior of frontal spatium to anterior ocellus (Fig. 16 E). MESOSOMA. Dorsum of mesosoma densely and strongly punctate on scapula, mesoscutum (slightly less so dorsomedially on disc) and scutellum (Fig. 24 E); metanotum mostly sparsely punctate, punctures on median area (Fig. 28 E); dorsum of propodeum with numerous but small punctures, many of them separated by more than their own diameter (Fig. 28 E). Mesopleuron densely punctate medially, broadly impunctate posteriorly and laterally; upper panel of metapleuron densely punctate dorsally, impunctate ventrally; lower panel of metapleuron with numerous faint punctures mostly effaced by vestiture; lateral panel of pronotum sparsely, minutely punctate. Scutellum and metanotum without median longitudinal carina (Fig. 28 E). Dorso-median area of propodeum without distinct tubercule medially (Fig. 28 E). METASOMA. Metasoma with weak division between anterior and ventral faces of S 2 in lateral view (Fig. 32 E); tergites mostly uniformly but not very densely punctate, T 2 with paired round impunctate areas laterally (Figs 32 E, 36 E). T 2 without basal elevation (gradulus) (Fig. 36 E). WINGS. Fore wing with two submarginal cells and one recurrent vein. Costal, first submarginal and marginal cells with short setae. COLOUR AND VESTITURE. Head red on antennae, frons above frontal spatium, vertex except for ocellar triangle, and behind upper lobe of eye (Figs 16 E, 20 E); remainder of body black (Fig. 8 E). Vestiture pale on front of head (albeit almost absent above frontal spatium), darker brown on occiput, black on mesosoma and metasoma with dense, appressed, white pile present posterolaterally on mesosoma. Wings dark brown with purple reflections. Male STANDARD RATIOS (n = 4). L: 14.8 – 18.0 mm (mean = 16.9 mm); CR: 1.07 – 1.13 (mean = 1.10); OOR: 1.62 – 1.83 (mean = 1.71); CLR: 0.61 – 0.76 (mean = 0.67); MER: 1.27 – 1.33 (mean = 1.30); OMR: 0.93 – 1.03 (mean = 0.97); FRR: 1.73 – 2.04 (mean = 1.86); MSR: 0.79 – 0.85 (mean = 0.82); TER: 1.45 – 1.54 (mean = 1.50). HEAD. Head densely punctate on frontal area and spatium, frons and vertex moderately but shallowly punctate (Figs 18 G, 22 G). MESOSOMA. Dorsum of mesosoma more or less densely punctate, punctures becoming sparser and / or shallower on dorsum of propodeum (Fig. 26 G). Lateral panels of mesosoma as for female. Scutellum and metanotum without median longitudinal carina (Fig. 30 G). Dorso-median area of propodeum without distinct tubercule medially (Fig. 30 G). METASOMA. Metasoma with weak division between anterior and ventral faces of S 2 in lateral view (Fig. 33 G); tergites uniformly and densely punctate (Figs 34 G, 38 G). T 2 without basal elevation (gradulus) (Fig. 38 G). WINGS. Same as female. COLOUR AND VESTITURE. Antennal flagellum brown / red to varying extent (Fig. 10 G); head yellow on frons above frontal spatium, vertex except spot of varying size around ocellar triangle, and behind upper lobe of eye (Figs 18 G, 22 G); remainder of body black. Vestiture pale (whitish or yellow) on head, mesosoma and T 1 – T 3 with black apical fringe on T 4 – T 6 (Fig. 10 G). Wings dark brown with bronze reflections. GENITALIA. Ventral side of paramere sparsely setose (Fig. 40 M), dorsal side with sparse long setae on most of its surface (Fig. 39 M); volsella with a few long setae apically, cuspis volsellaris with a few hairs apically and a row / cluster of long hairs basally (Fig. 42 M); volsella bearing sparse sensory cones on its external margin and a very narrow lamella on its internal margin (Figs 39 M, 40 M). External margin of paramere subparallel, rounded apically (Figs 39 M, 40 M); aedeagus with nine teeth, the last apical one much reduced (Fig. 42 M), serrated margin straight and sharply flattened apically (Fig. 42 M).
