  • rugatula. Pheidole (Pheidole) risi var. rugatula Santschi, 1933e: 109 (s.w.) ARGENTINA. Raised to species: Wilson, 2003: 745.

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

Description

From Wilson (2003): DIAGNOSIS Similar in various traits to Pheidole aper, Pheidole bambusarum, Pheidole brevicona, Pheidole dyctiota, Pheidole laeviventris, Pheidole lutzi, Pheidole risii, Pheidole senilis,Pheidole sigillata, Pheidole trachyderma and Pheidole traini, differing as follows.

Major: rugoreticulum confined to small patch posterior to antennal fossa on each side of head; entire rest of head carinulate except frontal triangle and mid-clypeus; all of dorsal surface of mesosoma transversely carinulate, and carinulae on pronotal dorsum curve down to pronotal sides as rugulae; hairs along posterior dorsal half of head profile of uniform short length, about half of Eye Length, and those along anterior dorsal half mostly 1.5–2.0! as long; postpetiole from above spinose.

Minor: posterior third of head and all of promesonotal dorsum rugoreticulate; propodeal spines reduced to denticles; occiput only slightly narrowed, but with nuchal collar.
