  • dione. Pheidole rufipilis var. dione Forel, 1913l: 225 (s.w.) ARGENTINA. Raised to species: Wilson, 2003: 286.

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


From Wilson (2003): A member of the fallax group, most similar to Pheidole bergi, Pheidole cordiceps, Pheidole dentata, Pheidole eidmanni and Pheidole nitidula, distinguished as follows.

Major: antennal scapes reaching within 2X their maximum width to occipital corners; rugoreticulum on each side of head forming a band from eye laterally to antennal fossa and forward slightly anterior to eye; carinulae on frontal lobes limited to their lateral margins and extending posteriorly to midway between eye and occipital margin; propodeal spines small, equilaterally triangular; pronotal profile in dorsal-oblique view a single convexity, and mesonotal profile subangular; postpetiole from above laterally subangulate; pronotum smooth; pilosity dense and long, many hairs longer than Eye Length.

Minor: pilosity long, some hairs 2X Eye Length; propodeal spines reduced to denticles; mesonotal convexity in dorsal-oblique view subangulate; occiput in frontal view feebly convex.

MEASUREMENTS (mm) Lectotype major: HW 1.26, HL 1.34, SL 0.94, EL 0.18, PW 0.62. Paralectotype minor: HW 0.60, HL 0.66, SL 0.84, EL 0.14, PW 0.40.

COLOR Major: body and appendages plain light brown.

Minor: body plain light brown, appendages yellowish brown.
