From Wilson (2003): DIAGNOSIS Known to me only from a syntype minor, as illustrated (syntype majors could not be located in the Forel Collection). Closest to and possibly the same as Pheidole ambigua (q.v.). Distinguished in the minor caste by the sparse pilosity; propodeal spines reduced to denticles; narrowed occiput with nuchal collar; and the pattern of sculpturing, including the absence of carinulae on the mesosoma.
MEASUREMENTS (mm) Syntype minor: HW 0.54, HL 0.66, SL 0.74, EL 0.12, PW 0.34.
COLOR Minor: concolorous medium brown, appendages a slightly contrasting yellowish brown.
Figure. Syntype, minor. Scale bars = 1 mm.
ARGENTINA: Rosário de la Frontera, Salta. Musee d'Histoire Naturelle Genève minors only, syntype majors could not be located - as reported in Wilson (2003)
