Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
A light brown member of the diligens group, closest to Pheidole williamsi of the Galápagos Islands but also with some similarities to Pheidole vafella, as well as Pheidole rufipilis and the mostly South American species listed with rufipilis (q.v.), differing from williamsi as follows.
Major: light brown; pronotum in side view smoothly rounded, and single-lobed in dorsal-oblique view; occiput strongly concave; petiolar node high, its apex rounded.
Minor: petiolar node in side view high, and its dorsal border nearly flat in rear view.
MEASUREMENTS (mm) Holotype major: HW 1.10, HL 1.12, SL 0.74, EL 0.16, PW 0.54. Paratype minor: HW 0.50, HL 0.60, SL 0.66, EL 0.12, PW 0.32.
COLOR Major: body and most of head light brown; appendages and anterior third of head a slightly contrasting yellowish brown.
Minor: body and most of head light brown; gena and appendages yellowish brown.
Specimens from Lima in the Museum of Comparative Zoology are somewhat darker.
