Pheidole cubaensis

Evidently a rare species: few collections have been made despite its conspicuously large size. I found a colony in Blanco’s Woods, Las Villas Province, Cuba, with winged reproductives on 25 June 1953. (Wilson 2003)

Nomenclature

 *  cubaensis. Pheidole cubaensis Mayr, 1862: 747 (s.w.) CUBA. Senior synonym of grayi Mann: Wilson, 2003: 624.
 * grayi. Pheidole cubaensis var. grayi Mann, 1920: 426 (s.w.) CUBA. [Unresolved junior primary homonym of grayi Forel, above.] Junior synonym of cubaensis: Wilson, 2003: 624.

Description
From Wilson (2003): DIAGNOSIS A large, dark reddish brown member of the scrobifera group.

Major: deep antennal scrobes present; rear third of the dorsal head surface rugoreticulate; propodeal spines moderately long and slender; postpetiole cornulate; a small subpostpetiolar process present; pilosity short, dense, and erect.

Minor: postpetiolar node diamond-shaped; propodeal spines long, slender, and straight; venter of head transversely carinulate; dorsa of head and mesosoma almost entirely foveolate and opaque.

A unique species, placed in the scrobifera group tentatively because of the habitus of the major, but the minor shows overall resemblance to the tristis-group species Pheidole alayoi, Pheidole macromischoides and Pheidole naylae of Cuba and Pheidole androsana of the Bahamas.

MEASUREMENTS (mm) Major (“var. grayi” syntype): HW 1.92, HL 2.16, SL 0.86, EL 0.20, PW 0.82. Minor (“var. grayi” syntype): HW 0.66, HL 0.72, SL 0.82, EL 0.14, PW 0.44.

COLOR Major and minor: body dark reddish brown, appendages dark yellow to yellowish brown.
