Pheidole laevifrons Mayr   HNS 1887: 598.

types Naturhist. Mus. Wien.

etymology L laevifrons   HNS , smooth or polished front, presumably alluding to the mostly smooth, shiny dorsum of the head of both castes.

Diagnosis A small, yellow member of the diligens   HNS group, distinguished as follows.

Major: cephalic sculpturing limited to the anterior third of the head, level with and anterior to the eyes; moderately abundant pilosity; relatively short propodeal spines. Close to peregrina , but major with much shallower occipital cleft in frontal view, thinner petiolar peduncle and node in side view, and more mesad placement of cephalic rugoreticulum.

Minor: thicker propodeal spines and longer scapes. Also similar to triconstricta   HNS but with much denser pilosity, shallower occipital cleft, and bilobous as opposed to trilobous promesonotal profile in dorsal-oblique view.
