This species occurs in lowland to mid-elevation wet forest. Minor workers have been collected at baits. One major worker has been collected, at a bait along with minor workers.
Identification
With a unique morphometric profile. Minor worker: the most distinctive character is the postpetiole, which is much longer than wide in dorsal view and flask-shaped. The postpetiole shape combined with large size and foveolate face should distinguish it from all other species. Major worker: head subrectangular versus with sides more convex and posterior margin more cordate (Pheidole bulliceps, Pheidole galba, Pheidole gigas, Pheidole hirsuta, Pheidole huacana); vertex lobes foveolate overlain by reticulate rugulae versus with arcing subparallel rugae (Pheidole arcifera, Pheidole rhea) or relatively smooth and shining (Pheidole astur, Pheidole auropilosa, Pheidole bergi, Pheidole geraesensis, huacana, Pheidole oxyops, Pheidole trageri); base of scape terete versus flattened (Pheidole claviscapa); propodeal spines long versus short (Pheidole tigris, trageri); first gastral tergite shallowly foveolate anteriorly, grading to smooth and shining posteriorly, versus more uniformly foveolate, opaque (Pheidole vorax).
