Comments. Based on females alone, a reliable identification of this species is impossible. It is worth noting here the discovery of this species belonging to the P. grisescens -group, which has not been previously recorded from the Mascarenes. This genus is very widely distributed, mainly in the Pacific Ocean, with numerous species described from the Hawaiian Islands and Japan. Only three species of the P. grisescens -group are recorded from the Afrotropical Region, of which P. cogani Mathis, 1988 has been described from Seychelles (Mahé Is.) and P. pauliani Mathis & Wirth, 1979 only from Madagascar (Toliara). The third species, P. grisescens Hendel, 1913, is widely distributed in the Afrotropical, Australasian/Oceanian, and eastern Palaearctic Regions, but not yet reported from either the Mascarenes or Seychelles.
