Identification

Williams and LaPolla (2016) - Obtusely angled propodeum with flat dorsal and posterior faces; entire cuticle smooth and shiny; ectal surface of mandibles with deep longitudinal striations.

This species is nearly identical to Prenolepis imparis in worker morphology, but has a more robust mesosoma at the mesonotal constriction . The male genitalia of P. nitens bear a few key differences from those of P. imparis: (1) in P. nitens the genitalia are oriented posteriorly and in P. imparis they are oriented ventrally, curving downward; (2) in P. nitens the ental surface of the parameres is strongly concave and scoop-like and in P. imparis the ental surface is flattened; (3) in P. nitens the cuspi are longer; and (4) the genitalia of P. nitens are overall less hirsute than those of P. imparis.
