Description
Summary:Two new species of family Tanaopsidae, genus Tanaopsis, from Admiralty Bay (Antarctica) are herein described. Tanaopsis brevicorpus sp. nov. displays antennule article 1 about 1.5 times as long as wide, carapace as long as first three pereonites, both rami of uropod biarticulate with fusion line, and pleotelson short, more than twice longer than wide. Tanaopsis bamberi sp. nov. resembles other Antarctic species T. kerguelenensis in its habitus, antennule long and uropod uniarticulate. However, the new species can be distinguished from it by a combination of characters that includes maxilliped basis with long seta arising from tubercles; inner margin of cheliped fixed finger with three smooth sub-terminal spines; uropod subequal to pleotelson in length, and uropodal endopod about twice as long as exopod
