Description
A very large blackish (major) or reddish (minor) brown member of the fallax group, distinguished in the major by its long propodeal spines, largely rugoreticulate dorsal head surface, and almost completely rugulose and carinulate sides of the mesosoma; and in the minor by the rugulose mesopleuron and propodeum.
Similar to Pheidole ajax, Pheidole fiorii, Pheidole hector, Pheidole hirsuta and Pheidole jaculifera, differing in many details of body form, sculpturing, and pilosity, as illustrated.
MEASUREMENTS (mm) Holotype major: HW 1.88, HL 1.80, SL 1.04, EL 0.30, PW 0.84. Paratype minor: HW 0.78, HL 0.92, SL 1.16, EL 0.22, PW 0.60.
COLOR Major: body blackish brown, head also with a faint reddish tinge; mandibles dark reddish brown; scape and legs except tarsi medium brown; funiculus and tarsi brownish yellow.
Minor: gaster dark brown, rest of body medium reddish brown; appendages light reddish brown.
