Type species. Uristes gigas Dana, 1852 View in CoL , monotypy.

Included species. Uristes View in CoL contains 2 species: U. gigas Dana, 1849 View in CoL ; U. subchelatus ( Schellenberg, 1931) View in CoL .

Incertae sedis. Uristes abyssi ( Norman, 1900) (family unknown); U. albinus (K.H. Barnard, 1932) (family unknown); U. dawsoni Hurley, 1963 (family unknown); U. entalladurus J.L. Barnard, 1963 ( Lysianassidae View in CoL , Tryphosinae ); U. georgianus ( Schellenberg, 1931) (family unknown); U. natalensis K.H. Barnard, 1916 (family unknown); U. paramoi ( Schellenberg, 1931) View in CoL .

Removals. Uristes perspinis J.L. Barnard, 1967 to the tryphosine genus Cedrosella Barnard & Karaman, 1987 based on gnathopod 1 with a tapering first coxa and a short carpus, a non-constricted inner ramus on uropod 2 and a moderately cleft telson.

Uristes abyssalis ( Stephensen, 1925) is tentatively removed to the tryphosine genus Gronella Barnard & Karaman, 1991 , based on mandible molar triturating, gnathopod 1 coxa is slightly tapering, carpus short, propodus margins subparallel and the telson moderately cleft . The condition of the male antenna 2 peduncle (with or without brush setae) and the condition of the inner ramus of uropod 2 (constricted or not) needs to be verified to confirm the generic placement.

Uristes barbatipes ( Stebbing, 1888) is removed the tryphosine genus Tasmanosa Lowry & Kilgallen, 2014 based on the well-developed antenna 1 accessory flagellum and the triturating molar, maxilla 2 inner plate slightly shorter than outer, the distinctive carpus and propodus of gnathopod 1.

Uristes serratus Schellenberg, 1931 View in CoL and U. yamana Chiesa & Alonso de Pina, 2007 View in CoL appear to be congeneric, and belong to a yet to be described genus in the Uristidae View in CoL based on the absence of a callynophore in the female and apparently in the male, the compressed carpus of gnathopod 1 and the cleft telson.

Uristes adarei ( Walker, 1903) ; U. antennibrevis J.L. Barnard, 1962 ; U. californicus Hurley, 1963 ; U. mediator J.L. Barnard, 1962 View in CoL ; U. stebbingi ( Walker, 1903) ; U. sulcus Griffiths, 1974 are removed to the tryphosine genus Tryphosella Bonnier, 1893 based on the triturating molar, maxilla 1 with a 6/5 setal-tooth arrangement, the tapering coxa of gnathopod 1.

Uristes velia J.L. Barnard, 1961 is removed to the tryphosine genus Cheirimedon Stebbing, 1888 based on the maxilla 1 setal-tooth arrangement; gnathopod 1 carpus short and propodus margins subparallel; pereopod 4 with weak posteroventral lobe; and telson deeply cleft .

Diagnostic description. [based on type species] Antenna 1 peduncle article 1 without anterodistal lobe; accessory flagellum not forming cap covering callynophore or flagellum with an elongate article 1 (at least twice as long as article 2) partially covering callynophore. Antenna 2 without brush setae. Mandible molar ridge-like, narrow, setose with narrow distal triturating surface. Maxilla 1 outer plate a well developed 7/4 crown. Maxilla 2 inner plate slightly shorter than outer plate. Gnathopod 1 subchelate; coxa 1 large, about as long as coxa 2, subrectangular with straight anterior margin or distally subovate; ischium short (length less than 2 × breadth); carpus short (length 1 to 2 × breadth) to long (length 2 to 4 × breadth); propodus margins subparallel or slightly tapering. Uropod 2 inner ramus not constricted. Telson deeply cleft .

Remarks. As Chisea & Alonso (2007) point out Uristes is in need of revision. The diagnosis provided here is based on the type species. Of the 23 species currently assigned to Uristes , only two remain. Eight of these species are so poorly described that they cannot be placed.

Based on the subchelate first gnathopod with a large coxa with a straight anterior margin and a short carpus Uristes appears to be most similar to the Arctic/boreal genera Anonyx and Onisimus . It differs from both in having a ridge-like narrow setose molar with a distal triturating surface and in not having an accessory flagellum cap.

Distribution. Southern Ocean and southern Australian waters.
