From Wilson (2003): DIAGNOSIS A medium-sized, yellowish species of uncertain affinities.

Major: head moderately elongate, its anterior dorsal surface carinulate and with no rugoreticulum; pilosity sparse, nearly absent from margin of the head in full-face view; entire mesosoma and waist foveolate and opaque; humeri in dorsal-oblique view prominently raised and narrowly lobate; postpetiole from above elliptical.

Minor: occiput broad, lacking nuchal collar; entire head, mesosoma, and waist foveolate and opaque; pilosity sparse, largely absent from margin of head in full-face view.

The sparse pilosity in both castes may be due to decomposition.

MEASUREMENTS (rom) Major (Campo Limpo, Sao Paulo): HW lAO, HL 1.54, SL 0.66, EL 0.20, PW 0.68. Minor (Campo Limpo, Sao Paulo): HW 0.56, HL 0.62, SL 0.58, EL 0.10, PW 0.36.

COLOR Major: head and mandibles clear reddish yellow; meso soma brownish yellow; gaster medium brown; antennae and legs clear dark yellow.

Minor: head medium yellowish brown; mesosoma, waist, and appendages light yellowish brown; gaster medium brown.
