Pheidole specularis

The species occurs in both lowland and montane rainforest, where the colonies nest both in dead wood on the forest floor and in live plant cavities and under epiphytes; workers have been observed attending extrafloral nectarines (Longino 1997).

Description
DIAGNOSIS Similar to Pheidole chalca, Pheidole daphne, Pheidole floridana, Pheidole nebulosa, Pheidole quercicola and Pheidole stomachosa, differing as follows. Major: mostly reddish yellow; head in full-face view subrectangular; posterior dorsal profile of head flat, not convex; promesonotal profile raised, semicircular; humeri from above subangular, extending beyond rest of pronotum below and only moderately prominent, along with mesonotal convexity in dorsal-oblique view; propodeal spines robust, more than half as long as the propodeal basal face anterior to them; all of mesosoma and most of dorsal surface of head foveolate and opaque; gaster completely smooth.

Minor: head subrectangular in side view; occiput broad and slightly concave; propodeal spines robust and half as long as propodeal basal face; all of head, mesosoma, and gaster foveolate and opaque; gaster completely smooth and shiny.

MEASUREMENTS (mm) Holotype major: HW 0.82, HL 0.88, SL 0.40, EL 0.10, PW 0.44. Paratype minor: HW 0.44, HL 0.46, SL 0.36, EL 0.10, PW 0.30.

COLOR Major: all of body and appendages medium reddish yellow except for gaster, which is brownish yellow.
