Abstract
The paper discusses the first record of the association between the medusa Lychnoriza lucerna Haeckel, 1880 and the decapod Libinia spinosa Milne-Edwards, 1934 in neritic waters of Argentina. Our results allow us to conclude that the symbiotic relation between these two species is a common phenomenon. The crab L. spinosa is located in the subgenital pockets of L. lucerna such that one-half of its cephalothorax is exposed to the outside. The crabs feed at the expense of the medusa, ingesting some portion of its food. A few specimens of the crab have been found, mostly females; the only male was of a somewhat larger size.
