Smith (1942), for the synonym commutatum - Major. Length 4-5 mm.

Eye extremely small, indistinct, apparently placed beneath general surface of head, and only observable after careful examination. Superior border of mandible with remarkably large, blunt, angular, basal tooth; margin deeply excised between this tooth and masticatory border; masticatory border usually with a number of small, irregular teeth, which may often be worn off. Antennal scape remarkably robust, short, less than three times as long as its greatest width; funiculus exceedingly short and broad, all segments, except first two and last, very noticeably broader than long. Antennal socket open in front, that is, without a flange (this best seen from above). Posterior border of head, from above, deeply emarginate, forming distinct, blunt,• angular posterior corners; posterior corners not outwardly curved as in wheeleri. Thorax compressed. Pronotum without transverse carina. Promesonotum approximately two and a half times length of epinotum when measured from the point where the carina should be back to meso-epinotal suture; meso-epinotal suture broad, distinct, but not deep. Anterior half of promesonotum, in profile, convex; posterior half distinctly flattened; posterior part of promesonotum clearly elevated above base of epinotum. Base of epinotum meeting declivity in blunt, obtuse angle, which in some aspects does not appear much greater than a right angle. Petiole robust, subquadrate, approximately seven-eighths as broad as long. Postpetiole scarcely shorter than petiole but very clearly broader, approximately one and one-fourth times as broad as long, broader posteriorly than anteriorly.

Body and appendages unusually smooth and highly polished, with the following exceptions: Mandibles subopaque, coarsely and longitudinally striated, and bearing scattered piligerous punctures near the masticatory border; anterior declivity of pronotum, propleura, and sides of petiole and postpetiole faintly shagreened, subopaque; meso- and metapleura more coarsely granulate-punctate; meso-epinotal suture granulate-punctate, with also longitudinal striae; tarsi and funiculi opaque owing to the abundant pile. Head with small, scattered, but distinct punctures.

Hairs yellowish, moderately abundant, of variable length, apparently sparse or absent on sides of thorax and head: Appressed pubescence more visible on gaster than elsewhere.

Deep yellowish brown to reddish brown, with lighter petiole, post-petiole, gaster, and legs; mandibles and frontal carinae much darker, especially around borders.
