Types Mus. Comp. Zool. Harvard.

Etymology L yucatanaHNS, from the Mexican region of the type locality.

diagnosis A member of the " bicarinataHNS complex" of the larger piliferaHNS group, comprising agricolaHNS, aureaHNS, barbataHNS, bicarinataHNS, centeotlHNS, cerebrosiorHNS, defectaHNS, gilvescensHNS, macclendoniHNS, macropsHNS, marcidulaHNS, paiuteHNS, pinealisHNS, xerophilaHNS, yaquiHNS, and yucatanaHNS, which complex is characterized by the large to very large, forward-set eyes in both castes; and, in the major, the occipital lobes lacking any sculpturing (except in aureaHNS); the posterior half of the head capsule almost entirely smooth and shiny; and the postpetiolar node seen from above oval, elliptical, or laterally subangular (cornulate in cerebrosiorHNS). P. yucatanaHNS is distinguished by the following combination of traits.

Major: in side view, promesonotal juncture subangulate; propodeal spines reduced to right angles; occiput sprinkled with sparse but coarse foveae; faint carinulae extend from behind eye to occipital corners; postpetiolar node from above laterally subangulate. Minor: in side view propodeal spines reduced to right angles.
