Abstract
This is a valid species, and not a form of P. cressoni as it is given by Metz. Externally the two are easily seperable. P. cressoni has the propodeum coarsely sculptured, while Mesilla has it, very finely wrinkled. The eighth ventral plates of the males are quite different, and are therefore figured. In cressoni the apical lobes are much shorter than the pedicel attaching them to the plate; in Mesilla they are longer than the pedicel.
