Pheidole nitidicollis Emery  HNS  1896g: 79. Pheidole dimidiata var. nitidicollis Emery  HNS  1896g: 79.

TYPES Mus. Civ. Stor. Nat. Genova

Etymology L nitidicollis  HNS  , shiny neck, referring evidently to the smooth rear of head.

Diagnosis A small, yellow member of the flavens  HNS  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  HNS  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 arhuaca  HNS  , flavifrons  HNS  , minutula  HNS  , other species listed as close to arhuaca  HNS  , and members of the " flavens  HNS  complex" listed under flavens  HNS  (q.v.).

Measurements (mm) Lectotype major: HW 0.80, HL 0.84, SL 0.44, EL 0.10, PW 0.40. Minor (Nevis): HW 0.42, HL 0.44, SL 0.40, EL 0.06, PW 0.24. Color Major and minor: yellow.

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

biology Unknown.
