Iae. Bayly, GLADIOFERENS HENRY (COPEPODA, CALANOIDA) DISCOVERED IN ANTARCTICA - G-ANTARCTICUS SP-NOV DESCRIBED FROM A LAKE IN THE BUNGER HILLS, Polar biology, 14(4), 1994, pp. 253-259
A new species of Gladioferens is described from a freshwater lake in t
he Bunger Hills, Greater Antarctica. A key to the six species of Gladi
oferens is provided for both sexes. Most species of the subgenus conta
ining G. antarcticus sp. nov. are remarkable in possessing asymmetries
in the second legs (male) and fourth legs (female). This suggests tha
t the mating behaviour of these species may be radically different fro
m that in most heterarthrandrian calanoids and calls for further study
. However, G. antarcticus is more primitive than its consubgeners in h
aving, in the male, symmetrical second legs and 3-segmented endopods i
n the fifth legs. The genus shows a highly disjunct distribution (Aust
ralia, New Zealand and Bunger Hills) and its biogeography is now of ou
tstanding interest.
