  • delicata. Pheidole delicata Wilson, 2003: 406, figs. (s.w.) BOLIVIA.

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


A medium-sized, mostly dark brown member of the flavens group whose major has a bicolored head and mesosoma; long, erect hairs on the promesonotum; propodeal spine reduced almost to a denticle; the petiolar node apex narrow; postpetiole seen from above oval; longitudinal carinulae covering almost all of the head, including the central part of the clypeus (but not the occiput, which is smooth); and mesosoma almost entirely smooth and shiny.

Similar in some but not all of these traits to Pheidole chalca, Pheidole lucaris and Pheidole ulothrix, differing in additional details of body form, sculpturing, pilosity and color, as variously described above and illustrated.

MEASUREMENTS (mm) Holotype major: HW 1.00, HL 1.00, SL 0.56, EL 0.14, PW 0.44. Paratype minor: HW 0.60, HL 0.62, SL 0.52, EL 0.12, PW 0.40.

COLOR Major and minor: head anterior to the level of the eyes and sides of the prothorax and mesothorax brownish yellow; appendages light brown.
