Two new species of the genus Tanzanapseudes Bacescu, 1975 (Tanaidacea: Apseudomorpha: Tanzanapseudidae) from mid-west Australia

Two new species of the apseudomorphan tanaidacean genus Tanzanapseudes are described from coral reefs of Western Australia. This genus belongs to the monogeneric family Tanzanapseudidae, which is recorded here for the first time from Australia. Tanzanapseudes nieli n. sp. differs from the other members of the genus by a specific pattern of minute spines and setae on pereonites, and by a combination of two other characters: a pleotelson distal process with a smooth outer margin and a short and spinose first article in the antennule. T. levis n. sp. has the anterolateral processes on its carapace and distal processes on its pleotelson uniquely smooth. A key for identification of Tanzanapseudes species and an amended diagnosis are given.
