DIAGNOSIS A medium-sized, yellow member of the flavens group characterized by a nearly complete absence in major and minor of sculpturing anywhere behind the anterior half of the head, the reduction of the propodeal spine to an obtuse angle, the very small size of the propodeal spiracle, shallow occipital concavity in full-face view, and abundant long pilosity. The major is further distinguished by its overall flattened mesosomal dorsal profile and laterally angulate postpetiole.
