Comments. This is the first record for Colombia and South America, but previously known from Mexico, Guatemala, Belize, Honduras, Nicaragua, and Costa Rica (Wilson 2003, Longino 2009a). The P. walkeri soldier from Colombia has face sculpture like that of the Honduran type on AntWeb (CASENT0645893) except that in the latter, carinulae originating in frontal lobes abruptly diverge posteriorly to reach the sides of the head below its midheight, while in the Colombian specimen these carinulae reach the sides of the head slightly above mid-head.
