Actinopyga capillata n. sp., with nocturnal habits, has first been observed in the Mascarene Islands, but has a wide Indo-West Pacific distribution. The new species is clearly separated from its congeners by its colour pattern and by the presence of very long and thin dorsal tube feet. Actinopyga capillata n. sp. is compared with Bohadschia mitsioensis Cherbonnier, 1988, with which it shares similar ossicle forms.
