Pheidole nubila EmeryHNS, new status
Pheidole triconstricta var. nubila EmeryHNS 1906c: 153.
Types Mus. Civ. Stor. Nat. Genova.
Diagnosis A member of the diligensHNS 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 triconstrictaHNS, 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 animaHNS, diligensHNS, gagatesHNS, piceonigraHNS, radoszkowskiiHNS, and stigmaHNS. 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.
