. Mandibles subtriangular, with a weak basal angle, a pair of apical teeth and variable dentition proximally, and no basal groove. Median portion of clypeus forming a raised triangular rostrum which projects past the anterior margin of the clypeus, sometimes with a short medial tooth. Frontal lobes small and closely approximated. Eyes small, often reduced to a single enlarged ommatidium, located on the sides of the head anterior of the head midline. Metanotal groove usually only shallowly impressed, though the mesosomal profile is often distinctly discontinuous due to a gradual posterior depression of the mesonotum. Mesonotum and propodeum much narrower than the pronotum, but the propodeum itself not narrowing significantly dorsally. Propodeal spiracles small and round. Metapleural gland orifice with a posterior U-shaped cuticular lip and a lateral groove. Metatibial spur formula (1p). Arolia prominent. Petiole nodiform to nearly squamiform. Gaster with a weak to strong girdling constriction between pre- and postsclerites of A4. Head, mesosoma and petiole usually heavily punctate, striate, or rugoreticulate, the gaster shiny or lightly punctate. Head and body with sparse to scattered pilosity and fairly light pubescence. Color variable, orange to black. Note: An undescribed hypogeic
