Pheidole of the Osa Peninsula; Species Sorted by Webers Length

WWL = worker Webers length, WSI = worker scape index, SHW = soldier head width, SCI = soldier cephalic index, SSI = soldier scape index. Face sculpture: "punct." = uniformly foveolate, "smooth" = smooth and shining, "rugose" = wrinkled, "costate" = with rounded ridges, "silky" = shagreened, "mixed" = combinations, such as foveolate with overlying rugae, or foveolate with smooth medial space, "varies" = intraspecifically variable, usually from smooth and shining to varying degrees of punctation.
