Description
DIAGNOSIS A member of the fallax group resembling Pheidole chiapasana, Pheidole dentata, Pheidole humeridens, Pheidole industa, Pheidole laeviventris, Pheidole madrensis and Pheidole maja in various characters, distinguished as follows.
Major: in full-face view the occipital margin is deep, with a subangular nadir; rugoreticulum of head extends in a swath from eye to antennal fossa; carinulae of dorsal surface of head extend almost to midpoint between level of eyes and level of occiput, and foveolation extends well beyond the midpoint; humerus in dorsal-oblique view angulate, and pronotal profile bilobose; propodeal spines strongly developed; postpetiole from above elliptical, with angulate lateral margins; anterior and posterior margins of pronotal dorsum carinulate.
Minor: closely resembles that of tetra in the crassicornis group (q.v.).
MEASUREMENTS (mm) Holotype major: HW 1.16, HL 1.24, SL 0.76, EL 0.18, PW 0.64. Paratype minor: HW 0.56, HL 0.66, SL 0.76, EL 0.14, PW 0.40.
COLOR Major: light reddish brown except for gaster, which is medium reddish brown.
Minor: concolorous plain medium brown; appendages light brown, changing to yellow on the tarsi.
