Wheeler, W.M., 1908
P. humeralis is evidently a rare species. During their intensive collecting in western Texas, Moody and Francke (1982) found the species only once, four colonies in Kinney County at 220 meters nesting in open clayey soil. (Wilson 2003)

Major: reddish yellow, with pale brown spot on vertex; head elongate, its posterior ventral profile flat; humeri strongly developed and subangulate, in dorsal view overhanging the rest of the pronotum beneath them and in dorsal-oblique view extending more than 4 higher above the metanotal groove than the mesonotal convexity; propodeal spines robust, as long as half the propodeal basal face preceding them; postpetiole from above oval.
Minor: posterior half of head and all of pronotum smooth and shiny; in dorsal-oblique view, humerus subangulate and promesonotal profile behind it flat before dropping to metanotal groove; occiput broad, its margin strongly concave.
