Description

From Wilson (2003): A member of the “jujuyensis complex” of the larger fallax group, comprising Pheidole araneoides, Pheidole cuevasi, Pheidole durionei, Pheidole jujuyensis, Pheidole kugleri, Pheidole leonina, Pheidole leptina, Pheidole lucretii, Pheidole lupus, Pheidole paraensis, Pheidole punctithorax, Pheidole tijucana, Pheidole wallacei and Pheidole wolfringi. P. durionei is distinguished as follows.

Major: antennal scape exceeding occipital corner by 2X its own maximum width; carinulae on dorsal surface of head reaching almost all the way to the occiput, which is foveolate and opaque; rugoreticulum on head stretches on each side from eye to antennal fossa and anteriorly almost to the anterior border of the head; margins of pronotal dorsum foveolate; propodeal spines equilaterally triangular; postpetiole from above diamond-shaped, with angular lateral margins.

Minor: propodeal spines reduced to barely discernible denticles; region mesad to and forward from eyes foveolate; occiput narrowed, with nuchal collar.

MEASUREMENTS (mm) Lectotype major: HW 1.20, HL 1.34, SL 1.22, EL 0.24, PW 0.60. Paralectotype minor: HW 0.52, HL 0.74, SL 1.08, EL 0.16, PW 0.40.

COLOR Major: body and appendages light reddish brown except for gaster, which is plain medium brown.

Minor: concolorous brownish yellow.
