Pheidole nitidicollis

This species is only known from type specimens. Nothing is known about its biology.

Identification
See the description in the nomenclature section.

Distribution
Described from Costa Rica by Emery, listed from Ceará, Brazil by Kempf (1972), and identified by me from series collected on Nevis in the Lesser Antilles, as well as Kingston, Jamaica. Pheidole nitidicollis is thus widespread and may be transported (as to Nevis) by human commerce. (Wilson 2003)

This taxon was described from Costa Rica.

Description
From Wilson (2003): DIAGNOSIS A small, yellow member of the flavens group whose major has a prominent, rounded humerus that rises well above the mesonotum in dorsal-oblique view, a roughly semicircular outline of promesonotum in side view, and an oval postpetiolar node. Similar to tenerescens but with the major possessing a low mesonotal convexity present (in side view), longer cephalic carinulae, larger propodeal spine and spiracle, and with a brown as opposed to yellow gaster. See also the less similar Pheidole arhuaca, Pheidole flavifrons, Pheidole minutula, other species listed as close to Pheidole arhuaca, and members of the “flavens complex” listed under flavens (q.v.).
