All of the species in the genus appear to be termitophagous and all are superbly adapted to this specialised predatory life style. Observations of some species have found them to be rather helpless when placed in an exposed, open situation. Weber described what happened when he found a worker “just beneath the soil surface under a thin cover of dead leaves”. The ant was “completely helpless when exposed to the daylight and writhed about when placed on the ground or in my palm. It made no attempt to run away, curling and uncurling without stinging, though it had a long, stout sting”. In other words, it seemed unable to walk when removed from its specialised habitat and placed on a surface where it could not use its specialised legs. If not discovered within a termite nest, individuals are occasionally found in the top soil or the root-mat below the leaf litter layer, where their short, powerful, spiny legs facilitate their movement. (Weber 1949, Bolton and Fisher 2008).

Holotype. TL 4.5, HL 0.81, HW 0.79, CI 98, ML 0.52, MI 64, SL 0.57, SI 72, PW 0.62, WL 1.31.
With characters of the genus and the feae group. Head capsule in full-face view appears about as long as broad, or slightly longer than broad, CI 98–101 in material examined. Mandibles smooth with scattered minute punctures. Masticatory margin of mandible weakly crenulate. Basal angle of mandible rounded, without a differentiated basal tooth. Dorsum of head with scattered punctures on smooth cuticle; the punctures on sides of head denser than on dorsum, and also with weak striation within the antennal fossae and on the sides, especially anteriorly. Metatibia with only normal setae dorsally but its anterior surface, at the apex and approximately opposite the pectinate spur, with two much stouter spiniform seta with bases close together. With mesosoma in profile the dorsal outline of the propodeum slopes only shallowly downward from the mesonotum; the more or less flat mesonotum passes into the sloping propodeum through a smooth, shallow curve. Petiole node in dorsal view broader than long. Pronotal dorsum with distinct broad, shallow foveolate punctures, the spaces between them with weakly rugulose superficial sculpture. Anterior mesonotum also with a few widely scattered broad, shallow punctures, but these are more sparse and less distinct than on the pronotum. Colour a light brownish yellow.
Non-paratypic. TL 4.5-4.6, HL 0.78-0.82, HW 0.79-0.81, CI 99-101, ML 0.48-0.52, MI 59-64, SL 0.57-0.58, SI 72-74, PW 0.62-0.64, WL 1.30-1.34 (3 measured). As holotype.
