Description

From Wilson (2003): DIAGNOSIS Similar to Pheidole bellatrix, Pheidole bison and Pheidole napoensis, differing from them and other tristis-group members as follows.

Major: promesonotum large, descending to the metanotum through a nearly vertical face half as long as the basal face of the propodeum; antennal scrobe present; posterior third of dorsal head surface smooth; postpetiole from above cornulate; rugoreticulum present between eye and antennal fossa; strong, convex postpetiolar process present; anterior rim of pronotal dorsum carinulate, rest of promesonotum smooth and shiny.

Minor: semicircular carinulae cover promesonotum except for center, which is rugoreticulate.

MEASUREMENTS (mm) Lectotype major: HW 1.30, HL 1.54, SL 0.62, EL 0.16, PW 0.82. Paralectotype minor: HW 0.52, HL 0.56, SL 0.40, EL 0.08, PW 0.32.

COLOR Major: body and mandibles medium reddish brown, other appendages reddish yellow.

Minor: gaster light brown, rest of body light yellowish brown, appendages yellow.
