A member of the crassicornis group, similar to Pheidole crassicornis, Pheidole diversipilosa, Pheidole porcula, Pheidole tetra and Pheidole vallicola, and differing in the following combination of traits.
Major: reddish to dark brown; rugoreticulum of head forms a broad swath from eye to frontal carinae; pilosity very dense, forming a thick fringe of short hairs around the head and a thick mat of hairs of short to medium length on the first gastral tergite; petiolar node in side view tapered to a blunt point at the apex; postpetiolar node laterally acute-angulate; basal segment of scape 2! broader than distal segment.
Minor: dark brown; posterior dorsal half of head and promesonotal dorsum smooth and shiny.
MEASUREMENTS (mm) Holotype major: HW 1.54, HL 1.58, SL 0.86, EL 0.20, PW 0.76. Paratype minor: HW 0.54, HL 0.68, SL 0.74, EL 0.14, PW 0.38.
COLOR Major: head rich medium reddish brown, with broad area of vertex covering central half of head capsule dark brown; body dark brown; legs medium brown.
Minor: most of body and antennae dark, almost blackish brown; lateral wings of clypeus and legs medium brown.
