Body length -
female: 6.6 mm (1 specimen)
male: 7.2 mm (1 specimen)
Female. Large eyes that cover almost the entire
head. Al shorter than A2. Al with short, stout
1 st article of the flagellum followed by two small
articles. Pl simple; propod and dactyl with
slightly denticulated posterior border. P2 with
strongly sinulated border of merus; carpus, propod and dactyl with serrated margins. P7 with
oval base and convex posterior margin. Rami of
3rd pair of uropods acutely pointed and with serrated margins.
Male. Similar in body shape to female except for
1st article of flagellum of Al, which is longer and
thinner in males.
Family Vibilidae
Remaks
The genus Cyllopus at present includes two species, C. magellanicus and C. lucasii. The distribution of both is confined to Antarctic waters. The
presence of two additional segments at the end
of the 1st antenna and the convex posterior margin of the P7 allows the easy identification of C.
magellanicus from the congeneric species, C. lucasii.
Distribution
C. magellanicus is widely distributed from the
Antarctic to South Georgia. Its distribution
range extends from the Antarctic continent up to
the subtropical convergence (Weigmann-Haass
1983). According to Barnard (1930), Bary (1959),
Hurley (1960), Kane (1962), Vinogradov (1966)
and Semenova (1976), C. magellanicus is present
also in the Antarctic sector of the Pacific and Indian Oceans. The species therefore has a circumpolar distribution, being limited in its diffusion
by the intensity of the Western winds. In the
Straits of Magellan, it was sampled exclusively
from 100-200 mat the mouth of the Pacific entrance.
