The tryphosine genera Photosella gen. nov and Tryphosella Bonnier, 1893 (Crustacea: Amphipoda: Lysianassoidea: Lysianassidae: Tryphosinae) in Australian waters

摘要

Within the lysianassid amphipod subfamily Tryphosinae the new genus Photosella is established with three included species: P. charlotteae (Lowry & Stoddart, 2009); P. miersi (Stebbing, 1888) and P. mucronata (Pirlot, 1936). The genus Tryphosella is rediagnosed and thirteen new Australian species are described: T. betka sp. nov.; T. bicheno sp. nov.; T. chinchilla sp. nov.; T. cooee sp. nov.; T. fortescue sp. nov.; T. freycinet sp. nov.; T. martrudan sp. nov.; T. rodondo sp. nov.; T. sorell sp. nov.; T. tathra sp. nov.; T. toowoomba sp. nov.; T. tuckanarra sp. nov. and T. wangaratta sp. nov. Tryphosella camela and T. orana are redescribed. There are now 19 species of Tryphosella known from Australian waters. The 79 species currently attributed to Tryphosella are carefully assessed: 40 species are confirmed as definitely Tryphosella; 24 species are considered as possibly in Tryphosella, but cannot be confirmed or denied because of insufficient evidence; and 15 species are excluded from the genus.
