Distribution map of Xanthocalanus hirtipes by geographical zones
Loc:
Azores, Bay of Biscay, off SW Ireland, Porcupine Bank, Barrow Strait, Ellesmere Island, W Baffin Bay, W & SE Greenland, Norway, Arct. (Barents Sea, Franz Josef Land, Amunsen Basin, Laptev Sea), ? Jones Sound, off British Columbia (rare)
N: 23
Lg.:
(1) F: 5,8; M: 5; (134) F: 4; (1134) F: 4; {F: 4,00-5,80; M: 5,00}
Rem.: bathypelagic.
This form resembles Xanthocalanus fallax.
For Vanhöffen (1897 a) the new species is closer X. minor and X. agilis by the P5 structure, but more hairy, the last thoracic segment ended in short point. The size is the doble than the mediterranean species.
