Remarks.
In the original publication, only one collection number was assigned to the ZMH - K paratypes, even though the specimens were collected at four different stations. Here, we assigned a new collection number to three lots (see above); the original number given by Mühlenhardt-Siegel (2011 a) is retained by the first lot listed herein.
Diagnosis.
Carapace with 2 teeth laterally at posterior part; pseudorostrum more than half as long as remainder of carapace, with 2 teeth ventrally; antennal notch with 3 to 4 teeth above. Antenna 1, accessory flagellum longer than basal article of main flagellum; Uropod, peduncle length 0.8–0.9 endopod length; endopod longer than exopod (after Mühlenhardt-Siegel 2011 a).
Distribution.
Southern Ocean, 1973–4678 m depth.
