types Naturhist. Mus. Wien.
etymology L laevifronsHNS, 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 diligensHNS 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 triconstrictaHNS but with much denser pilosity, shallower occipital cleft, and bilobous as opposed to trilobous promesonotal profile in dorsal-oblique view.
