Description
Summary:International audience n. ssp. is described and illustrated on the basis of new specimens from the Antarctic shelf in the Ross Sea. The material was collected off the Victoria Land coast during the 19th Antarctic expedition of the Italian research vessel in 2004. Ledoyer, 1993 was first obtained during the EPOS 3 campaign at Halley Bay in the Weddell Sea. A redescription based on further material from the Weddell Sea was published by Petrescu and Wittmann (Zool Med Leiden 77:557–630, 2003), which shows several differences to the newly collected material from the Ross Sea. The most obvious differences from n. ssp. to Ledoyer, 2003 are the absence of four spines on the merus of the second pereiopod, a lower number of setae on the uropodal endopod, a gap between spines on the peduncle article 1 of antenna 1, and a higher number of articles in both flagella of antenna 1.
