Pheidole guilelmimuelleriHNS Forel

Pheidole guilelmimuelleriHNS Forel 1886a: 210. Syn.: Pheidole guilelmimuelleri var. gustaviHNS Forel 191 le: 302, n.syn. Raised to species level in this monograph: feraHNS.

Types Mus. Hist. Nat. Geneve.

Etymology Named after the collector, William (Guilelmi) Muller.

diagnosis A large reddish brown species, similar to antillanaHNS of the Lesser Antilles and aviaHNS, bucculentaHNS, hetschkoiHNS, heyeriHNS, hortonaeHNS, mamoreHNS, praesesHNS, rhytiferaHNS, and sarcinaHNS of South America.

Major: propodeal spines long, stout, and nearly erect; postpetiole cornulate; sculpturing of dorsal surface of head consists entirely of longitudinal carinulae, which are confined to the anterior two-thirds of the head capsule except for two carinulae that proceed to the occiput along the midline; promesonotal dorsum almost completely covered by transverse carinulae. The major is very similar to that of bucculentaHNS, but the minor is easily distinguished, as illustrated.

Minor: occiput, sides of head mesad to the eyes, and lateral margins of the pronotal dorsum rugoreticulate; remainder of dorsal surface of head weakly carinulate; propodeal spines long, thin, and erect.

Measurements (mm) Lectotype major: HW 2.10, HL 2.12, SL 0.98, EL 0.20, PW 1.02.

Paralectotype minor: HW 0.82, HL 0.84, SL 0.94, EL 0.14, PW 0.54.

Color Major: concolorous light reddish brown.
