Description:
In the present paper results of taxonomic investigations on 1137 specimens of Cyllopus magellanicus DANA 1853 and of 730 specimens of Cyllopus lucasii BATE 1862 are reported. A brief diagnosis and key are given for the genus and the species. For the first time larvae of the pantochelis stage of these species are described. The habitus of the larvae are very similar, small differences were found on the structures of the pereopod 3-6. Due to special morphological similarities it is concluded that the larvae of both species display a parasitic way of life like Vibilia. The distribution of the species in the Antarctic Ocean is circumpolar: C. magellanicus occurs probably only within the West Wind Drift while C. lucasii was found within both the West and the East Wind Drift. Remarkable is the occurrence of a great number of males of C. magellanicus in the uppermost layer (30-0 cm depth), meanwhile the females of this species were found only in deeper layers.
