Description

Total length of workers around 2 mm. Body color uniformly blackish brown; antennal scapes and legs yellowish brown. Mandibles each with 6 teeth. Antennal scapes exceeding posterior margin of head by 2/5 their length; with short erect hairs, which are shorter than the width of a scape shaft, and moderately abundant subdecumbent pubescence. Funicular segments each as long as wide or longer than wide. Eyes moderate in size. Pronotal dorsum convex in profile; mesonotal dorsum straight; metanotal groove incised dorsally. Head and gaster with erect hairs. Pronotal dorsum with four long erect hairs, mesonotal dorsum with four hairs, none on propodeum. Hind femora and tibiae with suberect hairs.

Remarks

This species resembles P. flavipes, P. ryukyuensis, and P. yaeyamensis. It may be distinguished from the latter by its dark body coloration, the shorter erect hairs and moderately abundant pubescence of the antennal scapes.
