Remarks.

Mühlenhardt-Siegel (2005 b) designated an additional paratype (SMF 30450) deposited at the SMF. 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 new collection numbers to three lots (see above), whereas the original number given by Mühlenhardt-Siegel (2005 b) is retained by the lot containing specimens collected in Stat. 340.

Diagnosis.

Carapace smooth. Maxilliped 3, merus with 1 tooth. Uropod peduncle longer than telson; endopod tri-articulate, longer than exopod; article 1 longer than articles 2 and 3 combined (after Mühlenhardt-Siegel 2005 b).

Distribution.

Southeast Atlantic, Angola Basin, 5389–5420 m depth.
