Descriptions of two new species of alpheid shrimps from Japan and Australia, with notes on taxonomy of Automate De Man,

Shelf off Western Australia. Automate hayashii appears closest to the poorly known A. salomoni Coutière, 1908. Bermudacaris australiensis sp. nov., the second species of the genus, represents the first discovery of the genus in the Indo-Pacific. The type species of Bermudacaris Anker and Iliffe, 2000, B. harti Anker and Iliffe, 2000, was described from anchialine caves of Bermuda, while the unique specimen of Bermudacaris australiensis sp. nov. was collected from an apparently typical marine environment. Relationships among the species of Automate De Man, 1888, Bermudacaris and Coronalpheus Wicksten, 1999 are discussed. Characters separating these three closely related genera, including the development of the rostrum, the shape of the eye-stalks, the absence of the appendix masculina, and the features of the first pereopods, are reassessed. Three informal species groups are recognized in Automate, showing certain heterogeneity of this genus
