Description
DIAGNOSIS From Wilson (2003): Similar especially to Pheidole antillana of the Lesser Antilles, but differing in the following combination of traits.
Major: shallow scrobes, whose surfaces lack sculpturing; small rugoreticula present mesad to the eyes and on the dorsal pronotal margins; dorsal surface of occiput mostly smooth but with scattered foveae; mesonotal convexity subangulate; postpetiole strongly cornulate.
Minor: occiput and lateral posterior quarters of cephalic dorsum transversely carinulate; humerus subangulate in dorsal-oblique view; most of promesonotum rugulose, with margins loosely rugoreticulate. Color of major and minor: reddish yellow.
MEASUREMENTS (mm) Lectotype major: HW 2.02, HL 2.16, SL 0.90, EL 0.22, PW 0.82. Paralectotype minor: HW 0.82, HL 0.86, SL 0.92, EL 0.14, PW 0.54.
COLOR Major: body medium reddish yellow, appendages light reddish yellow.
Minor: body dark reddish yellow, appendages light reddish yellow.
Figure. Upper: lectotype, major. Lower: paralectotype, minor. Scale bars = 1 mm.
