  • cameroni. Pheidole cameroni Mayr, 1887: 595 (s.), 605 (w.q.) ECUADOR. Senior synonym of monticola: Cameron, 1892: 67; Dalla Torre, 1893: 89. See also: Wilson, 2003: 176.

From Wilson (2003): A small, light brown member of the diligens group distinguished in both major and minor by low mesonotal convexity, shallow metanotal depression in side view, and hence a more cylindrical form of the mesosoma in side view than is usual for Pheidole; a small convexity atop the metanotal depression in side view; and large, robust propodeal spines. Especially similar to Pheidole alpestris, but with much less dense and more subrecumbent pilosity in both major and minor, carinulae present mesad to the eye of the major, pronotal convexity absent in side view in major, and other traits as illustrated.

MEASUREMENTS (mm) Lectotype major: HW 1.14, HL 1.14, SL 0.82, EL 0.20, PW 0.60. Paralectotype minor: HW 0.60, HL 0.66, SL 0.64, EL 0.12, PW 0.34.

COLOR Major: concolorous light to medium brown.

Minor: body and mandibles concolorous light brown; other appendages brownish yellow.
