New species from the Bohai Sea, China, re-evaluation of the validity of Kornev & Chertoprud, 2008 and proposal of gen. n. (Copepoda, Harpacticoida, Canthocamptidae).

Two new species of the genus Por, 1960 (Canthocamptidae) are described from the Bohai Sea, eastern China. and differ from their congeners by the presence of two instead of three outer spines on P2-P3 exp-3. They can be differentiated from each other by (1) number of inner setae on P3-P4 enp-2; (2) anterior margin of antennulary segment 7 of male; (3) ornamentation of male abdomen; (4) sexual dimorphism on P2 endopod and P3-P4 exp-3; and (5) differences in length of setae on male P5. Some observations in the original description of Por, 1960 are reinterpreted and the type material of (Wells, 1965) is re-examined. Comparison between the type species of Kornev & Chertoprud, 2008 and the four known species of shows the former as a junior subjective synonym of the latter. Consequently, Kornev & Chertoprud, 2008 is formally transferred to as (Kornev & Chertoprud, 2008), A key to species and an updated generic diagnosis of are presented. The taxonomic status of the genus Huys & Thistle, 1989 is re-evaluated. The characters of its type species, (Coull, 1973), indicate that the latter (and - by inference - the genus ) should remain in the Danielsseniinae. Mielke, 1997 is fixed as the type species of a new genus and placed in the Hemimesochrinae (Canthocamptidae) as the putative sistertaxon of Huys & Thistle, 1989. The relationships and potential synonymy of the genera Coull, 1973, Huys & Thistle, 1989 and George & Schminke, 2003 are briefly discussed.
