Chart showing the geographical distribution (white circle) in the seas surrounding the Antarctic continent.
Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951). |

For Vervoort (1965, p.130) finds increasingly difficult to separate thsi species from A. longicaudatus in the material of the Atlantide Expedition; the females brought to the latter are slightly smaller and the females have the caudal rami covered with distinct though short spiniforom hairs. The females of A. glacialis generally are bigger, but the smaller females have about the same size as the large females of A. longicaudatus. In the female A. glacialis the caudal rami may be completely nude, but usually there are fine hairs along the inner border. None of the female specimens in the Atlantide Expedition has the inner margial spine of the 2nd exopodal segment of P5 as figured by Brodsky (1950, fig.258); this spine in the Atlantide specimens may be slightly denticulated externally, but never as coarse as appears from Brods's figure.
For Mazzocchi & al. (1995, p25) it seems to be difficult to separate A. glacialis from A. longicaudatus. In longicaudatus females, the caudal rami and anal somite are covered by spiniform hairs; in glacialis the caudal may be completely naked, but usually there are fine hairs along the internal borders. The caudal rami and anal somite of females are coarsely coverd with fine hairs on the ventral side (no spiniform hairs as in longicaudatus) and the genital somite without the remarkable swelling on the left side (in dorsal view) characterizing longicaudatus females. In the specimens from the Straits of Magellan (as in Vervoort, 1965), the female does not have the blunt, coarsely serrulated internal marginal spine of the exopod 2 of P5 as figurated by Brodsky (1950, fig.258) but this spine has short hairs along its length. This spine reaches the base of the 3rd inner marginal seta of the exopod 3 (in longicaudatus it reaches the 2nd marginal seta as reported by Tanaka, 1964).
Apparently, only the males of glacialis and longicaudatus can easily be separated by the P5 (only in longicaudatus does the left exopod end with a very long apical spine).
For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 1700.
M. Hure & al; (2018, p.5, 10) record for the first time this species in the Adriatic Sea, but does not appeared in the tables 1 and 2, probably very rare/or not abundant. | | | Last update : 14/06/2022 | |
