Abstract

Ichthyoxenus puhi (Bowman, 1962) is reported for the first time from Mauritius on the host Gymnothorax griseus (Lacépède, 1803), expanding its distribution from Hawaii to the western Indian Ocean. I. puhi is characterized by its oval-shaped body, well-developed posterior lobes on the pereonites, lateral ends of pleonites longer than pereonite 7, pleotelson wider than long, pereopod 4 to 7 with a protruding merus, and a distinct lobe on the proximolateral surface of the basis.
