Abstract

Branchinella clandestina sp. nov. is described from the Queensland Paroo and B. mcraei sp.nov. from the Pilbara in Western Australia. Both have a simple frontal appendage consisting of a trunk and two branches, but differ from each other and other similar species such as B. affinis Linder, B. longirostris Wolf and B. latzi Geddes by many features. These two species increase the number of described Australian Branchinella to 31 species. The raising of B. nichollsi hattahensis Geddes and B. nichollsi buchananensis Geddes, both present in the Paroo catchment, to species status is confirmed with lectotypes designated and species descriptions provided. Similarities and differences between B. nichollsi, B. hattahensis and B. buchananensis are discussed.
