Description. MALE. Body length 9.0–11.0 mm. Coloration. Head and mesosoma black. Appendages black, except antennae brown apically. Metasoma black, except anterior 90% of T2 and S2 orange. Tibial spurs white. Forewing hyaline between veins, except apical third infuscated and dark streak in 2nd radial, 1st medial, apex of radial and base of 1st submarginal, veins brown; hindwing hyaline. Body clothed with whitish setae, except clypeus with orange-brown setae anteromedially, mesoscutum, axillae, anterior third of scutellum, posterior quarter of T2, T7 and S7 with blackish setae.
Head. Rounded subquadrate, posterolateral angles rounded. Head width 0.9 × pronotal width. Eye transversely ovate. Ocelli small; ocellocular distance 4.8 × length of lateral ocellus, interocellar distance 2.2 × lateral ocellus length. Occipital carina distinct. Front, vertex and gena densely punctate to reticulate and obscured by dense white recumbent setae. Gena ecarinate. Antennal scrobe broadly concave to eye margin, with prominent transverse carina above. Clypeus weakly convex, densely punctate and setose, having transverse subapical furrow with dense anteriorly facing orange-brown setae. Scape bicarinate. Flagellomere 1 1.8 × pedicel length; flagellomere 2 1.3 × pedicel length. Mandible obliquely tridentate apically, inner tooth larger than middle tooth; lacking dorsal or ventral projections. Maxilla and labium elongate. Maxillary palp 6-segmented, third and fourth segments slightly flattened and apically expanded, other segments almost cylindrical. Labial palp 4-segmented, second and third segments slightly flattened and apically expanded, other segments almost cylindrical.
Mesosoma. Epaulets elongate, connected to humeral carina. Pronotal dorsal and lateral punctation coarsely contiguous but obscured by dense recumbent setae; anterior face almost smooth. Tegula convex, glabrous except with long recumbent setae anterolaterally and posteromesally. Mesoscutal punctation coarsely contiguous; notaulus absent; parapsis indistinguishable; posterolateral corner forming a deeply punctate sharp lobe. Scutellum slightly convex, coarsely reticulate. Axilla produced posterolaterally as truncate tooth, coarsely contiguously punctate but smooth posteriorly; anterolateral axillar margin and posterolateral mesonotal lobe continuous. Metanotum surface obscured by dense shaggy mesally facing recumbent setae. Propodeum strongly convex, entirely coarsely and deeply reticulate except virtually impunctate adjacent to metapleuron. Mesopleural punctation coarsely reticulate dorsally becoming finer posteroventrally, mainly obscured by dense recumbent setae. Metapleuron setose but lacking well-defined punctures. Wings. Fore wing with moderate elongate sclerotized pterostigma; marginal cell broadly rounded and truncate apically; three submarginal cells, apical veins of third cell weak. Legs. Mid- and hind tibiae each with a few strong spines dorsally, distinct apical secretory pore on inner surface near base of inner spur; spurs finely serrate on margins.
Metasoma. T1 nodose, 0.5 × width of T2, with coarse punctures; apex with weak fringe of mesally directed recumbent setae. T2 with sparse punctures becoming denser near apex, interspaces smooth; apex with weak fringe of mesally directed recumbent setae; felt line 0.5 × lateral length of T2. T3–5 with dense fine and moderate punctures, covered with dense recumbent setae. T6 moderately punctate, covered with less dense recumbent and erect setae. T7 sparsely punctate with simple erect and decumbent setae basally, impunctate and shinning apically except for weak fringe of posteriorly directed setae. S1 with longitudinal medial carina. S2 sparsely punctate, strongly convex, somewhat swollen medially, having deep median ovate pit with small cluster of white setae. S3–6 sparsely and finely punctate, with erect and recumbent setae. Hypopygium smooth convex elongate, moderately and finely punctate, with weakly carinated lateral margins converging to apex, posteromedial margin produced as a narrowly rounded tooth. Genitalia (Figs 14–17). Free length of paramere elongate, more or less cylindrical, acute, weakly dorsally curved apically, with long ventro-interal fringe of long dense erect setae in basal third and scattered erect setae along internal and lateral margins. Cuspis lacking basal division or process, slightly expanded dorsally at base, ~0.7 × free-length of paramere, having few scattered short setae. Digitus short and weakly upcurved, slightly laterally flattened, ~0.1 × free-length of paramere, with a few scattered obscure punctures and setae. Parapenial lobe well developed, obliquely flattened and apically rounded in lateral view. Penis valve with vertical row of setae apically, ventral margin bidentate apically, teeth separated; anterodorsal area angulate and sharply raised.
FEMALE. Body length 3.7–5.8 mm. See Williams et al. (2011) for description of female.
