Redescription
Body. Length 5.60—6.40 (female), 5.50—6.95 (male - Fig. 79).
Head (Fig. 80). Black, shiny, coarsely punctured; paraclypei longer than clypeus and joined anteriorly, forming two triangular projections apically; clypeus moderately convex, bare; each paraclypeus with a submarginal row of 3 long hair-like setae; bucculae with fine hairs; ocular index 3.45—4.21; ocelli small, distance between ocelli about 2.1—3.8 times greater than the distance between an ocellus and an eye, ocellar index 7.0—14.0; rostrum extending beyond anterior coxae, but not reaching the middle coxae; length of antennal segments: I 0.24—0.38, II 0.35—0.45, III 0.41—0.63, IV 0.56—0.73, V 0.56—0.71.
Prothorax. Pronotum black or blackish brown, shiny, coarsely punctured, about 1.45—1.50 times broader than long (Fig. 83); its dorsal surface with scattered golden brown hairs; anterior margin deeply broadly concave, posterior margin concave centrally; lateral margins not serrated, narrowed anteriorly, each submargin with a row of 9—13 setigerous punctures bearing long hair-like setae; transverse postmedial impression shallow. Prosternum black or blackish brown, coarsely punctured; prosternal carinae very low, almost invisible, at first sight apparently absent. Propleuron black, shiny, coarsely and deeply punctured, lateral parts shallowly impunctate.
Mesothorax. Scutellum black with margins and apex more castaneous in colour, wider than long, punctation of disc crowded and coarse, median discal carina weakly developed, usually clearer apically; pilosity of scutellar disc sparse. Anterior part of mesopleuron punctured, evaporative area narrowed laterally to reach margin of mesopleuron. Corium castaneous or dark brown, its punctation sparser than that on pronotum and scutellum, punctures large, pilosity fine and sparse; costal margin with 4—6 setigerous punctures bearing long hair-like setae; membrane normally developed, usually narrower than abdomen, reaching or almost reaching the tip of abdomen, only sometimes surpassing it, veins simple or furcate, sometimes reticulate, darker than the remaining surface of membrane.
Metathorax. Metapleural evaporatorium broad centrally, laterally narrowed, peritreme elongated.
Legs. Anterior femur brown, bearing setigerous punctures on ventral side; anterior tibia clearly broadened apically (Fig. 81). Femora of middle pair with rows of small sharp spines ventrally; middle tibiae straight with black spines. Male hind femora ventrally with a row of strong spines (Fig. 82), the median one usually clearly longer and stouter; female hind femora ventrally with a row of short blunt tubercles; male hind tibiae with basal two-thirds strongly bowed outward (Fig. 82), apical third almost straight, ventral margin of basal two-thirds with two rows of strong tubercles and numerous long hairs; female hind tibiae straight, unmodified.
Abdomen. Sterna clearly impressed sublaterally, furrow along their lateral margins deep and well-developed; sterna ventrad of furrow coarsely punctured and bearing numerous setigerous tubercles (better developed in males than females), punctures in furrow much finer than elswhere on sterna; lateral margins of each segment with a row of 3—4 setigerous punctures, and with well-developed posteriorly projecting spine. Male genital capsule as in Fig. 88, paramere as in Figs 85—87. Female genital plates narrow (Fig. 89), densely punctate.
