Diagnosis.

Tricolourous, largely orange-red with cream and piceous / black markings. Black mark on stemmaticum extending to form a point on vertex. Mesoscutum, orange-red except for posterior 1 / 2 of middle lobe which is cream, and bordered postero-laterally by piceous markings.

Description.

Length of body 5.5 mm, fore wing 4.1 mm. Head. Antenna with 44 flagellomeres. Terminal flagellomere acuminate. First flagellomere 1.0 × longer than 2 nd and 3 rd, the latter 1.3 × longer than wide. Width of head: width of face: height of eye = 2.3: 1.1: 1.0. Face granulate with interrupted weak mid-longitudinal ridge. Inter-tentorial distance 1.4 × longer than tentorio-ocular distance. Malar suture impressed. Malar space 1.6 × as long as basal width of mandible. Antennal sockets strongly produced. Frons strongly impressed medially and behind antennal sockets with mid-longitudinal carina. Frons, vertex, and occiput granulate. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 1.2: 2.2. Mesosoma 1.5 × longer than high. Mesoscutum smooth, granulate medio-posteriorly, sparsely punctate; notauli impressed anterior 1 / 2, crenulated, shallow posteriorly. Scutellar sulcus shallow, narrow, finely crenulate. Scutellum smooth, sparsely setose without small pit medially behind sulcus. Median area of metanotum with complete mid-longitudinal carina. Propodeum largely smooth and shiny, coarsely rugose posteriorly, distinctly transversely striate near mid-longitudinal carina; mid-longitudinal carina complete, lamelliform, bordered narrowly by fine crenulations; posteriorly propodeum with short longitudinal carinae associated with longitudinal wrinkles. Wings. Fore wing. Lengths of fore wing veins r-rs: 3 RSa: 3 RSb = 1.0: 1.6: 4.7. Lengths of vein 2 RS: 3 RSa: rs-m = 1.3: 1.3: 1.0. Base of hind wing with large glabrous area distal to vein 1 CU. Legs. Lengths of fore femur: fore tibia: fore tarsus = 1.0: 1.1: 1.1. Lengths of hind femur: hind tibia: hind tarsus = 1.0: 1.1: 1.3. Claws with small acutely pointed basal lobe. Metasoma. T 1 coriaceous, 1.8 × wider than long, with pair of posteriorly uniting dorsal carina. T 2 1.1 × as long as T 3. TT 1–5 with coarse reticulate sculpture. Second metasomal suture and basal grooves of TT 4 and 5 deep, strigose. T 5 with postero-lateral margin convex, without emarginations. Coloration. Body mostly black except face laterally, malar space, mandible except apically, frons, and vertex laterally, T 1 except medially, T 2 except medially, TT 3–5 antero-laterally ivory white, maxillary and labial palps, pronotum, mesoscutum, scutellum, mesopleuron, metanotum except anteriorly yellow.
