[4] The head and abdomen segments are pigmented dark in contrast to the conspicuously yellowish thorax, matching the coloration of workers.

Soldiers of this species molt from sclerotized worker-like forms which are slightly smaller than the actual workers but otherwise appear to behave no differently.

[5] The imago of this species has a brownish black, broadly oval head capsule which is sparsely covered by long hair.

Nests are mainly characterized by their elongate shape that tapers into a central runway which is either flanked by gallery walls on either side and/or by downward sloping narrow ridges.

These narrow ridges are the most diagnostic feature of their nests, and are believed to aid in diverting rainfall from the central runway.
