A parasitic copepod, Amaterasia amanoiwatoi nov. gen., nov. sp. (Siphonostomatoida, Amaterasidae nov. fam.) is described together with its juveniles, including the copepodid stages, based on specimens recovered from galls formed on the fins of the fish, Xanthichthys lineopunctatus (Hollard, 1854), taken off Clarion Island, eastern Pacific, in 1957. This species resembles pandarid copepods, but is distinct in some characteristic features. It has gall-forming juveniles in its life cycle, which are referred to here as encysted copepodid stage. An advanced encysted copepodid 5 yielded an adult female developing inside it, on which the description of this new species is based. The encysted copepodid encysts and lodges inside a gall, with its caudal rami extending partly beyond the posterior orifice of the gall. All stages found probably are females. The encysted copepodid ingests exudates from the host through a ventral hole in the cyst wall. The encysted copepodid 1 is compared with caligid and pandarid copepodids. Some speculations are made on the possible life history of this species. Un copépode parasite, Amaterasia amanoiwatoi nov. gen., nov. sp. (Siphonostomatoida, Amaterasidae nov. fam.) est décrit ainsi que ses stades de développement, incluant les stades copépoditiques, à partir de spécimens obtenus de galles formées sur les nageoires du poisson Xanthichthys lineopunctatus (Hollard, 1854), pris en 1957 au large de l'île Clarion, Pacifique oriental. Cette espèce ressemble aux copépodes pandarides, mais s'en distingue par certains traits caractéristiques. Il présente, au cours de son cycle de vie, des stades juvéniles formant des galles, qui sont désignés ici comme stade copépoditique enkysté. Un copépodite 5 enkysté avait produit, à l'intérieur du kyste, une femelle adulte à partir de laquelle est fondée la description de cette nouvelle espèce. Le copépodite s'enkyste et loge à l'intérieur de la galle, avec ses rames furcales dépassant de l'orifice postérieur de la galle. Tous les stades trouvés sont probablement femelles. Le copépodite enkysté ingère les exsudats de l'hôte à travers un "trou" ventral de la paroi du kyste. Le copépodite enkysté 1 est comparé aux copépodites de caligides et de pandarides. Des hypothèses sont proposées sur l'histoire possible de la vie de cette espèce.
