Promesonotum longer and somewhat less convex above, epinotum proportionally longer and broader. Petiolar scale decidedly thicker, with convex anterior surface and very sharp superior border, which is more deeply and more angularly excised than in rogeri.

Very smooth and shining, like rogeri, with similar pilosity, but the hairs on the gaster less numerous and longer. Jet black; antennae and mandibles dark brown, scapes darker and more blackish, their tips and the basal funicular joints yellowish brown; femora black; tibiae very dark brown, paler at their bases and tips; tarsi and tibial spurs brownish yellow; last tarsal joint of each leg blackish.
