The new genus Collocherides, which is created for the reception of C. astroboae n. sp., is closely related to Collocheres. Whereas the species of Collocheres all are, as far as we know, ectoparasites of echinoderms, Collocherides was found endoparasitic in basket stars (Astroboa nuda, A. albatrossi) at Eilat (Israel), in the Dahlak Archipelago (Ethiopia), and in Indonesia.
