E t y m o l o g y: The species name refers to the small but distinct scopa of hind coxa.

D e s c r i p t i o n: Body length 11 mm. Flagellum filiform, with 33 flagellomeres; 1 st flagellomere 1.5 × longer than wide; about 5 th flagellomere square; widest flagellomere 1.3 × wider than long; preapical flagellomere 0.6 × as long as wide. Temple moderately and roundly narrowed behind eye. OED 1.3 × and OOD 1.3 × ocellar diameter. Frons coarsely rugose-punctate, dull. Face with rather dense punctures, shining. Clypeus with sparse punctures, strongly shining. Gena seen laterally 1.3 × as wide as eye, with sparse punctures ventrally. Malar space long, 1.4 × as long as width of the mandibular base and 1.3 × as long as 1 st flagellomere. Genal carina reaching hypostomal carina far from mandibular base; both carinae low.

Mesosoma covered with grey hairs. Notaulus shortly impressed at frontal margin of mesoscutum. Mesoscutum densely rugose-punctate, dull. Mesopleuron densely punctate, with striated rugae dorsally. Metapleuron coarsely rugose-punctate; juxtacoxal carina present. Scutellum almost flat, about as long as wide, with sparse punctures, without lateral carina. Propodeum rugulose-punctate. Area superomedia rectangular, slightly longer than wide. Anterior transverse carina (costula) absent. Mid coxa almost smooth ventrally. Hind coxa densely punctate, with small distinct scopa apico-ventrally (0.2 × as long as hind coxa). Hind femur 3.5 × longer than wide, with sparse punctures in ventral third and at base. Tarsi moderately widened; 3 rd mid tarsomere 1.3 × longer than wide. Hind tibia with c. 5 denticular spurs externally. Areolet pentagonal; frontal distance between veins 2rs-m and 3rs-m 2 × their width. Vein 1cu-a postfurcal by 2 × its width.

Metasoma oxypygous. Postpetiole distinctly widened, with distinct dorsal carina, lateral field 0.5 × as wide as median field; median field with c. 10 regular striae. Gastrocoelus strongly impressed, with longitudinal ridges. Thyridium transverse, 0.8 × as wide as the interval between thyridia. 2 nd and 3 rd tergites finely and densely rugose-punctate, dull. Ovipositor sheath slightly extending behind metasomal apex.

Color: black. Flagellomeres 7-13 ivory dorsally. Palps, mandible, clypeus, face except two paramedian black spots, orbits, vertex and scape red. Frontal orbit with narrow yellowish stripe. Frontal and upper margins of pronotum, mesoscutum and tegula red. Scutellum and postscutellum yellow. Side of postpetiolus and all tergites red. 2 nd to 4 th tergites with transverse black basal stripes; 6 th and 7 th tergites with median ivory spots. Coxae and trochanters black; fore and mid coxae apically, hind coxa dorsally and all trochantelli red. Femora black, ± reddish apically. Tibiae and tarsi red. Wings with yellowish infuscation.
