Sars, 1877), Arctic Ocean.

Diagnosis (after Larsen & Shimomura 2007). Female. Leptognathiid with cheliped fixed finger and dactylus simple. Uropodal exopod two-articled.

Remarks. Although deriving from a revision and splitting of the genus Leptognathia (Larsen & Shimomura op.cit.), this new genus is a pragmatic (and probably temporary) formation and is clearly polyphyletic, the only common feature among the largely disparate species being the bi-articulated uropod exopod. A significant problem faces potential revisers of Biarticulata, if no existing genus can accommodate transferred species, as no type species was designated.
