Two new species of Bryocamptus (Copepoda, Harpacticoida, Canthocamptidae) from the Russian Arctic and comparison with Bryocamptusminutus (Claus, 1863)
Two new species of Bryocamptus Chappuis, 1929 from the Russian Arctic from the Bryocamptusminutus species group are described: Bryocamptusputoranussp. nov. and Bryocamptusabramovaesp. nov.
