Morphological terminology and the format for descriptions generally follow those of
The genus is characterized by the labium prolonged into a tongue that is about 0.33 as long as the height of head; antenna with 15 flagellomeres; foveate groove on mesopleuron almost straight, inclined 45° from horizontal; propodeum moderately long with a narrow median longitudinal carina or basal keel between the base of the propodeum and transverse carina; fore wing vein 2

♀: Body length 3.9 mm (without ovipositor); fore wing length 3.6 mm. Lateral ocellus separated from eye by ca. 2.5–2.7× ocellar diameter. Flagellum of antenna filiform, short, with 15 flagellomeres; flagellomeres elongate, first flagellomere 3–4x as long as centrally broad; penultimate flagellomere 1.6–1.7× as long as centrally broad; all flagellomeres covered by short hairs, in addition to apical long bristles. Malar space as long as basal mandibular width. Clypeus broad, usually smooth on lower part, granulate and punctate on upper part. Mandible punctate basally, upper tooth much longer than lower tooth. Face, frons, vertex and occiput finely granulate and usually finely punctate (punctures sometimes indistinct because of granulation). Temple finely and sparsely punctate, smooth between punctures; temporal orbits smooth without setae. Mesoscutum entirely granulate, indistinctly punctate; notaulus weak; mesopleuron almost smooth and punctate; epicnemial carina reaching to subalar prominence; foveate groove elongate, almost reaching to epicnemial carina, oblique, with some transverse wrinkles; metapleuron finely punctate. Propodeum with basal keel distinct, 0.75–1.0× as long as apical area; spiracle round and large, separated from pleural carina; apical area elongate, acute anteriorly, with apical longitudinal carinae reaching transverse carina anteriorly, alutaceous and coarsely punctate; dorsolateral areas usually smooth with fine, sparse punctures. Fore wing with vein 2
Head black except palpi, clypeus, and mandible yellowish, and malar space, scape, and pedicel reddish. Mesosoma predominantly black, sometimes partly with reddish tinge, particularly on pronotum and mesopleuron; legs yellowish except dorsum of metafemur, mesotibia, metatibia, and meso- and metatarsomeres brown. Wing membranes hyaline and weakly infuscate; pterostigma dark brown. Metasoma with segment 1 and dorsum of tergites 2–4 dark brown; remainder of metasoma yellowish.

♀: Body length 3.6 mm (without ovipositor); fore wing length 3.2 mm. Lateral ocellus separated from eye by ca. 1.6–1.8× ocellar diameter. Fagellum of antenna filiform, short, with 15 flagellomeres; flagellomeres elongate, first flagellomere 2.3–2.7× as long as centrally broad; penultimate flagellomere 1.3–1.4× as long as centrally broad; all flagellomeres covered by short hairs, in addition to apical long bristles. Malar space 0.7–0.8× as long as basal mandibular width. Clypeus broad, usually smooth on lower part, granulate and punctate on upper part. Mandible punctate basally, upper tooth much longer than lower tooth. Face, frons, vertex and occiput finely granulate and usually finely punctate (punctures sometimes indistinct because of granulation). Temple finely and sparsely punctate, smooth between puntures; temporal orbits smooth without setae. Mesoscutum entirely granulate, indistinctly punctate; notaulus weak; mesopleuron almost smooth and punctate; epicnemial carina reaching to subalar prominence; foveate groove short, oblique, scrobiculate; metapleuron finely punctate. Propodeum with basal keel distinct, 0.7–0.8× as long as apical area; spiracle round and large, separated from pleural carina; apical area elongate, acute anteriorly, with apical longitudinal carinae reaching transverse carina anteriorly, alutaceous and coarsely punctate; dorsolateral areas usually smooth with fine, sparse punctures. Fore wing with vein 2
Head black except for palpi, clypeus, mandible, malar space, scape, and pedicel reddish. Mesosoma black except for pronotum, pleura, and sterna reddish; legs generally yellowish except base of pro- and mesotibiae, apex of metafemur, metatibia (with darker spots at base and apex), and metatarsus brown. Wing membranes generally hyaline and weakly infuscate; pterostigma dark brown. Metasoma with segment 1, dorsum of tergite 2, and basal parts of tergites 2–5 brown; remainder of metasoma yellowish.
