New aquatic Oniscidea (Crustacea: Isopoda) from groundwater calcretes of Western Australia

Abstract

Three blind new species of Haloniscus Chilton (Scyphacidae s.l.) from groundwater calcretes in Western Australia are described: H. tomentosus, H. longiantennatus and H. stilifer. A diagnosis of the genus and a key to the species are proVided, and its distribution is briefly discussed. Haloniscus stepheni Nicholls and Barnes, is redescribed and transferred to the genus Andricophiloscia Vandel in the family Philosciidae. A further new blind philosciid species collected in the same calcrete system as H. longiantennatus and H. stilifer is described and tentatively ascribed to the genus Andricophiloscia (A. pedisetosa).
