Description
From Wilson (2003): DIAGNOSIS A medium-sized reddish yellow to brown member of the flavens group; both major and minor are immediately recognizable by the large, “shark-fin” shape of the humerus in dorsal-oblique view, meaning that the anterior margin is straight and the posterior margin convex in profile, tipped with an acute or right angle. Very similar to Pheidole angulifera, and in varying degree also to Pheidole arhuaca, Pheidole caulicola, Pheidole chalca, Pheidole nitidicollis, Pheidole mincana, Pheidole sagana, Pheidole tambopatae and Pheidole tragica in overall appearance but distinctive in the humeral shape and other traits in body shape, sculpture, pilosity, and color.

MEASUREMENTS (mm) Lectotype major: HW 0.94, HL 0.94, SL 0.46, EL 0.10, PW 0.48. Paralectotype minor: HW 0.50, HL 0.54, SL 0.58, EL 0.08, PW 0.34.

COLOR Lectotype major of schmalzi: body and appendages light brown, waist and gaster dark brown (rehi syntype major is yellowish brown; rata syntype major is light reddish yellow).

Paralectotype minors of schmalzi: body light to medium brown, appendages light brown. Syntype minors of synonymous rehi and rata: light brown.
