Body stout, shiny. Head massive, subcircular in anterior view, broader than mesosoma, nearly glabrous. Toruli not projecting. Ocellar tubercle not prominent. Ocellar hair patches absent. Compound eyes glabrous. Inner orbital furrows present. Posterior margin of gena distinct, but not carinate. Occiput diagonally striate. Malar spaces smooth, without conical protuberances. Malar sulci present. Female antenna with 13 segments, club consisting of six flagellomeres; male antennae 15 segments, filiform. Shape of dorsal margin of pronotal plate in anterior view broadly truncate, emarginate. Mesoscutum longer than wide, quite arcuate, without median mesoscutal carinae, with rows of punctures in position of notauli, parascutal impressions incomplete. Shape of posterior part of scutellum in dorsal view bluntly rounded. Lateral bars of scutellum striate. Scutellar foveae wider than long, deep and large. Dorsal surface of scutellum areolate-puntate. Scutellar plate suboval, posterior margin rounded, dorsal surface with midpit placed close posterior margin of plate, with punctures on each side, with a setae on either side. Anteroventral cavity of metapleuron subcircular, setose. Forewings of normal size, hyaline, apical margin with hair fringe, basal margin lacking hair fringe, with membrane pubescence mostly reduced hair bases, marginal cell closed, longer than broad. Metasoma sessile; base of syntergum with hairy ring present, remainder of metasoma glabrous. Micropunctures present on posterior 1/3 of the syntergum more or less visible.

The three genera can be separated by the following characters:
1 | Female antenna with F5 or F6 to F11 moniliform, club consisting of 6 or 7 flagellomeres (Figure |
|
– | Female antenna with F4 or F6 to F11 moniliform, club consisting of 6 or 8 flagellomeres. Dorsal surface of scutellar plate with punctures on each side with setae either one. Lateral bars of scutellum striate |
|
2 | Female antenna with F4 to F11 moniliform, club consisting of 8 flagellomeres. Scutellar plate posteriorly arched in lateral view (See Figure |

– | Female antenna with F6 to F11 moniliform, club consisting of 6 flagellomeres. Scutellar plate straight in lateral view (Figure |
