Preliminary investigations of hydrothermal vent harpacticoids from the Galapagos Rift resulted in the discovery of a new genus and species of Tantulocarida. Rimitantulus hirsutus gen. et sp. nov. is described on the basis of the tantulus larva and the male at an early stage of development. It is the first record of the subclass from hydrothermal vent habitats and is placed in the Basipodellidae which exclusively utilize copepods as hosts. The harpacticoid host Argestoides prehensilis gen. et sp. nov., which is known only from the male, shows affinities with both the Ameiridae and Argestidae and is placed genus incertae sedis in the latter primarily on account of the complete lack of sexual dimorphism on the swimming legs.
