The Tryphosa group (Crustacea: Amphipoda: Lysianassoidea: Lysianassidae: Tryphosinae).

The Tryphosa group is established within the tryphosine amphipods. It contains eight genera worldwide ( Bruunosa Barnard & Karaman, 1987; Glorieusella gen. nov.; Gronella Barnard & Karaman, 1991; Metambasia Stephensen, 1923; Pseudonesimus Chevreux, 1926; Schisturella Norman, 1900; Thrombasia J.L. Barnard, 1966; and Tryphosa Boeck, 1871). As part of the Tryphosa group we describe the new genus Glorieusella from Madagascar and four new species ( Schisturella rosa sp. nov., Thrombasia evalina sp. nov., Thrombasia umina sp. nov., Thrombasia saros sp. nov.) from eastern Australia.
