Moderately large; mostly black with lighter yellow to yellowish-orange markings on head and tergites 3–6; femora and trochanters apically white dotted; pterostigma anteriorly paler; face moderately punctate; inner margins of eyes subparallel; malar line moderately long; clypeus strongly transverse, sparsely and shallowly punctate; remainder of head coriaceous; antenna with 32 flagellomeres, penultimate flagellomere barely elongate; pronotum mostly smooth; mesopleuron and metapleuron moderately densely punctate with speculum largely smooth; mesoscutum roughly and densely punctate; punctation distinctly sparser on scutellum; area superomedia elongate; ovipositor long, apically sinuous. Male with inner margins of eyes diverging ventrally, ocelli and hind femur enlarged, femoral tooth long and narrow, mesoscutum mostly coriaceous with punctures along notaulus, area superomedia more slender, and metasoma darker with tergite 3 only partially yellowish-orange.
Moderately large and mostly black; differentiated from all other Afrotropical species by the combination of the mostly smooth pronotum, the coarsely punctate-granulate mesoscutum, the short post-ocellar line, the absence of a femoral tooth in females and the long ovipositor.
