Parhyale explorator, a new species of talitroid amphipod from the bay of Arcachon, France

Abstract

Parhyale explorator n. sp., is a new species of talitroid amphipod discovered in the Bay of Arcachon (France). P. explorator s most distinguishing features are the long tufts of plumose setae ventrally on antenna 2 which make it easy to differentiate from other species of the genus. This article présents a detailed description of the new species together with a discussion of amphipod systematics and the key, proposed by BARNARD (1979), that is developed using ail species found to date.
