Mandibles smooth and shiny apart from scattered punctures; apical margin armed with eight teeth.

With mesosoma in dorsal view, metanotal groove deeply impressed and straight; in profile, mesonotum distinctly convex; junction between propodeal declivity and lateral portion of propodeum slightly marginate; posterior margin of propodeum narrowly lamellate, forming obtuse angle at about the level of propodeal spiracle; mesosoma dorsum densely and finely reticulate-rugulose. With petiole in lateral view, node anteroposteriorly flattened, posterior margin medially notched in dorsal view.
