Longiflagrum amphibium, a new estuarine apseudomorph tanaid (Crustacea, Peracarida) from north-western Australia

Abstract

Australian tanaidacean material collected during spring 1993 and 1994 and autumn 1994 and 1995 in vicinity of Port Hedland and Oyster Island (NW Australia) included over 800 of specimens of a new species of apseudomorph, Longifl agrum amphibium sp. n. T e species is the fi fth to be described in this genus, and it was found in the intertidal zone, as the other species have been. T e new species is distin- guished from the other members of the genus by having the shortest fl agella in the antennule and by its oval pleopod basis.
