Tylos australis: a new species of Tylidae (Isopoda : Oniscidea) a family previously not recorded in Australia

Abstract

The Tylidae Milne-Edwards, 1840 is the sole family in the infra-order Tylomorpha Vandel, 1943 (Holdich et al. 1983) and is divided into two genera, Tylos Latreille, 1826, and Helleria Ebner, 1868 (Vandel 1960). Specimens collected from Bawley Point, N.S.W. belong to the genus Tylos. They are described as a new species, Tylos australis. The significance of the shapes of frontal processes in Tylos is discussed in terms of zoogeography.
