  • stomachosa. Pheidole floridana subsp. stomachosa Wheeler, W.M. 1917g: 459 (s.w.q.) JAMAICA. Raised to species: Wilson, 2003: 511.

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


From Wilson (2003): DIAGNOSIS Nearly identical to Pheidole bilimeki and Pheidole floridana (q.v.). Differs from both in the mostly smooth and feebly shiny pronotum of the minor, and possibly the weakly bilobous outline of the pronotum in dorsal-oblique view; and from bilimeki in addition by the complete or near absence of shagreening from the first gastral tergite. There also may be small differences in the major in pilosity (as illustrated) and color (described below).

MEASUREMENTS (mm) Lectotype major: HW 0.90, HL 0.96, SL 0.52, EL 0.12, PW 0.44. Paralectotype minor: HW 0.44, HL 0.48, SL 0.46, EL 0.10, PW 0.26.

COLOR Major: body dark yellow, with slight reddish overtones (hence faintly “orange”), appendages clear yellow.

Minor: concolorous yellow.
