Pheidole tenerescens Wheeler ^HNS

Pheidole tenerescens Wheeler ^HNS 1922e: 7.

Types Mus. Comp. Zool. Harvard.

etymology Presumably from L tener, soft, alluding to the relatively feeble sculpture.

Diagnosis As represented by the major, a small, yellow member of the flavens ^HNS group with prominent, rounded humerus that rises well above the mesonotum in dorsal-oblique view; a nearly perfectly semicircular outline of promesonotum in side view; a deep, circular metanotal groove with vertical anterior propodeal face in dorsal-oblique view; short pilosity; and mostly smooth, shiny body. Similar to nitidicollis ^HNS, but lacking a mesonotal convexity in side view, with shorter cephalic carinulae, smaller propodeal spiracle and spine, and yellow as opposed to medium brown gaster.
