| Abstract | Based on specimens of Paranannopidae collected from 30 to 123 m depth in Sassenfjord, Spitsbergen, two species of Paradanielssenia Soyer, 1970 (P. christineae sp. nov. and P. kathleenae sp. nov.) are described. These can be distinguished from known species by differences in the number of claviform aesthetascs on the mouthparts and in the arrangement or form of setae on the legs. A key to species of Paradanielssenia is provided. Mucrosenia gen. nov. (type species M. kendalli sp. nov.) is established on the basis of a single female and can be distinguished from all known paranannopid genera by the structure of the caudal ramus and the P2 endopod-2 which has no inner seta and a large mucroniform process at the outer distal corner. Psammis kliei Smirnov, 1946 is assigned to this genus as species incertae sedis. Danielssenia quadriseta Gee, 1988 is recorded for the first time outside its type locality in Oslofjord. Danielssenia spitsbergensis sp. nov. is described from a single male specimen and can easily be distinguished from other known species by the presence of only two outer spines on exopod-3 of P3-4. However, because of differences in the structure of the P2 endopod and P5, the species is placed incertae sedis within Danielssenia pending the discovery of the female. |
