Head (Figs 6B, 6C, 6G) depressed, temples short and parallel behind eyes, covered with sparse white short setae; frons transversely wrinkled, with long carina-like projection between antennal sockets; length of the ocellar-ocular distance 0.6× maximum diameter of lateral ocellus; ocelli small, hind ocellus not extended behind eye; temples and vertex wrinkled; occipital carina complete; antenna subapically sharply angled at a single joint, with 23 flagellomeres, 18 th flagellomere with two long sensillae; face about 0.6× as long as wide, reticulate rugose, tentorial pits deep; malar space 1.2× basal width of mandible, with strongly depressed subocular groove; clypeus 0.5× as long as wide, transversely wrinkled proximally and weakly rugulose distally, rounded apically.
Mesosoma (Figs 6D, 6E, 6F) almost glabrous; propleuron wrinkled; pronotum swollen apically, wrinkled, rugulose posteroapically, epomia present; mesoscutum elongate, wrinkled proximally, rugulose distally, with weak notauli; scutellum rugulose and postscutellum smooth; mesopleuron wrinkled, sparsely punctate ventrally; epicnemial carina absent; sternaulus indistinct; metapleuron rugulo-punctate; propodeum rugulose, with dorsal longitudinal carinae ending as long tooth-like projections; pleural and submetapleural carinae present; spiracles elongate, small.
Legs slender, hind femur 3.3× as long as wide; hind coxae sparsely punctate, fore and middle tibiae not swollen, narrower than femora; with V-shaped median ventral groove and subapical emargination; fore and middle trochantelli without apical tooth; tarsal claws simple.
Wings. Fore wing with vein 2 rs-m long, about 1.8× distance between 2 rs-m and 2 m-cu; vein cu-a basad of Rs&M by about 0.4 of its length; hind wing with distance between distal abscissa of Cu 1 and M about as long as vein cu-a.
Metasoma (Figs 6E, 6H) wrinkled; first tergite 2.2× as long as apical width, longitudinally wrinkled, with transverse grooves, carinae absent; second tergite 0.7× as long as apical width, longitudinally wrinkled, with two large basolateral and third central triangular swellings delimited by basolateral and subapical transverse grooves; third tergite 0.6× as long as apical width, with the same sculpture and structure as previous tergite; the remaining tergites smooth; ovipositor about 2.2× length of hind tibia, with the apical teeth; ovipositor sheaths densely pubescent.
Colour. Head, propleuron, pronotum and mesopleuron orange; vertex, mesoscutum, scutellum, postscutellum, propodeum proximally, and metapleuron brownish; subtegular ridge, mesopleuron posteriorly and propodeum laterally yellow; fore and mid legs orange with irregular yellowish-brown marks; hind coxae brownish dorsally, yellow ventrally, trochanter and trochantellus, tibia and tarsus brownish, tibia basally and femur reddish; metasoma generally brownish with apicolateral yellow marks on tergites 1–3 and apical bands on the remaining tergites; antenna tricolored: orange basally, yellow centrally, brownish apically; pterostigma brown, yellow basally; ovipositor sheaths and three stripes on fore wing brown.
Male. Unknown.
Distribution. Democtratic Republic of Congo.
