  • fera. Pheidole guilelmimuelleri var. fera Santschi, 1925d: 227 (s.w.) BRAZIL. Raised to species: Wilson, 2003: 689.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.


DIAGNOSIS From Wilson (2003): Similar in various traits to Pheidole amata, Pheidole ambigua, Pheidole celaena, Pheidole germaini, Pheidole peruviana, Pheidole rutilana, Pheidole schwarzmaieri, Pheidole superba and Pheidole vomer, differing as follows.

Major: distinct mesonotal convexity absent in side view, with promesonotal profile a continuous weakly convex curve that drops as a steep face to the metanotum; center of mid-c1ypeal carina projects forward as a process in dorsal-oblique view; posterior half of head smooth and shiny except for carinulae along the dorsal midline, which reach occiput; anterior half of head almost all carinulate, with no rugoreticulum; humeri subangulate in dorsal-oblique view; postpetiole diamond-shaped seen from above; apex ofpetiolar node acute in side view.

Minor: occiput narrowed, with a nuchal collar; apex of petiolar node acute in side view; central third of dorsum of head and almost all of meso soma foveolate.

MEASUREMENTS (mm) Lectotype major: HW 1.96, HL 1.24, SL 0.94, EL 0.24, PW 0.76. Paralectotype minor: HW 0.64, HL 0.74, SL 0.84, EL 0.14, PW 0.44.

COLOR Major: head and mandibles light reddish brown; rest of body plain medium brown; other appendages dark yellow.

Minor: body plain dark brown, appendages plain light brown.
