Nomenclature

 *  nubila. Pheidole triconstricta var. nubila Emery, 1906c: 153 (s.w.) ARGENTINA. Santschi, 1919f: 40. Raised to species: Wilson, 2003: 211.

Description
From Wilson (2003): A member of the diligens group distinguished as follows.

Major: pronotal dorsum bilobous (hence, promesonotum trilobous) in dorsal-oblique view; extremely sparse pilosity, which is entirely absent on the mesosoma; dense longitudinal carinulae covering all the frontal lobes and extending back over the vertex; rugoreticulum mesad to the eyes.

Minor: all of body except the gaster foveolate and opaque; pronotum with a second convexity in dorsal-oblique view. Close to Pheidole triconstricta, differing (among other traits) in the more extensive foveolae and carinulae, as well as thinner petiolar node, of the major; and darker color of both castes (q.v.).

See also Pheidole anima, Pheidole diligens, Pheidole gagates, Pheidole piceonigra, Pheidole radoszkowskii and Pheidole stigma.

MEASUREMENTS (mm) Lectotype major: HW 1.14, HL 1.18, SL 0.72, EL 0.20, PW 0.56. Paralectotype minor: HW 0.56, HL 0.64, SL 0.74, EL 0.14, PW 0.38.

COLOR Major and minor: reddish brown.

Type Material
ARGENTINA: Salta (no further locality). - as reported in Wilson (2003)

Etymology
From Wilson (2003): L nubila, cloudy, probably referring to the more foveolate and opaque condition of the body that distinguishes the form from Pheidole triconstricta.
