Holotype major worker and associated paratype minor worker: Costa Rica, Prov. Cartago, 5km E Tres Rios, El Alto de Ochomogo (J. Welch) [ MCZ ] (examined). New synonymy. Comments Wilson (2003) discussed character variation and synonymy in the widespread species P. radoszkowskii (a complete list of synonymy is not presented here). The species P. medialis is well within the range of variation for P. radoszkowskii in Costa Rica, and there is no evidence of discrete sympatric forms.
