Pheidole bruchi Forel 1914d: 274. Raised to species level in this monograph: brunnescens .

Types Mus. Hist. Nat. Geneve.

Etymology Named in honor of the Argentine entomologist Carlos Bruch.

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 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.
