Pheidole guilelmimuelleri  HNS  Forel

Pheidole guilelmimuelleri  HNS  Forel 1886a: 210. Syn.: Pheidole guilelmimuelleri var. gustavi  HNS  Forel 191 le: 302, n.syn. Raised to species level in this monograph: fera  HNS  .

Types Mus. Hist. Nat. Geneve.

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

diagnosis A large reddish brown species, similar to antillana  HNS  of the Lesser Antilles and avia  HNS  , bucculenta  HNS  , hetschkoi  HNS  , heyeri  HNS  , hortonae  HNS  , mamore  HNS  , praeses  HNS  , rhytifera  HNS  , and sarcina  HNS  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 bucculenta  HNS  , 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.
