Known only from the single worker holotype that was collected from the leaf litter of montane rainforest.


Rakotonirina and Fisher (2013) - Worker. Clypeus anteriorly wide and straight, with slight median notch; reddish ferruginous species with densely and finely reticulate-punctate sculpture; mandible smooth between punctulae; posterior margin of head concave; antennal scape not surpassing posterior cephalic margin; metanotal groove deeply impressed; dorsal outline of mesosoma with clearly convex mesonotum; posterolateral margin of propodeum bordered with narrow lamellae, which form an obtuse angle at about the level of the propodeal spiracle; petiole node anteroposteriorly flattened, its posterior margin medially notched in dorsal view. Anterior face of third abdominal segment straight, not forming a shallow impression; antennal scape and outer surface of tibiae without erect hairs; dorsum of head and rest of body covered with a few erect, slender hairs.
