VARIATION: Because the species seems to have an unusually large distribution range, we have documented specimens from two disparate localities in Costa Rica (Hone Creek and Osa Peninsula) and one in northern Panama (Cerro Colorado, figs. 140–151, 162–171), in addition to specimens from the type locality (Barro Colorado Island, Panama, figs. 127– 139, 152–161). Although there are of course differences among these specimens, they seem to represent individual rather than geographically correlated variation.

DISTRIBUTION: Costa Rica and Panama.
