Worker. Length 3 lines.-Shining ferruginous, or rufopiceous; sparingly pubescent. Head large, the vertex and front down to the insertion of the antennae, finely but rather distantly punctured; a deep central channel extends from the middle of the bead to its anterior margin; on each side the head is obliquely striated; the mandibles longitudinally striated. Thorax: the prothorax rounded in front, convex, subglobose, punctured on the sides, the disk impunctate; the metathorax oblong, the sides parallel, truncate posteriorly, rather obliquely so. Abdomen oblong, smooth and shining, with the apex pale rufo-testaceous.
The female has the head more strongly punctured, the mesothorax much larger, and the scutellum developed; the wings subhyaline, with the nervures testaceous; the prothorax, metathorax, and sides of the node of the peduncle strongly punctured.
Male. Length 2 1/2 lines.-Black, shining and pubescent: head and thorax strongly punctured; the head transverse, the eyes large and lateral; antenna; elongate, filiform; the antennae, tibiae and tarsi rufo-testaceous; wings as in the female.
Erichson only describes the worker of this species: the male and female are in the Museum Collection.
