can be recognized easily by the medially convex anterior margin of its clypeus and the presence of a shallow impression on the anterior face of its first gastral tergite. No striking morphological variation is observed in this species despite the great distance between collection localities in the south and the center of Madagascar.

is an endemic species found in mid-elevation areas of eastern Madagascar. In addition to the type locality, the species occurs in the PN Mantadia in the central east and in the PN Andohahela in the southernmost portion of the island. It was collected by sampling leaf litter in the central east of Madagascar and was only recorded once from a pitfall trap in Andohahela.
