| Abstract |
A total of 124 rotifer species was identified from 17 samples collected in Papua New Guinea, representing the first record of rotifers from the Island. Remarks on the taxonomy of Lepadella biloba Hauer (new status) are provided, a description of a hitherto unknown species in the genus Scaridium is presented. A majority of cosmopolitan or cosmo(sub)tropical, warmstenothermic species is reported. A single local endemic and one Australian species are found. Eleven species, including the new Scaridium, occur either exclusively in the freshwater biotopes of the floodplain of the river Sepik and in floodplain lakes in the lower Niger Delta, (Nigeria, 1, 2), or have also been recorded from other, similar habitats in tropical Asia and Australia. Two species, on the other hand, were previously known from either Europe or North America only. The littoral genera Lecane (27.4%), Lepadella (12.9%) and Trichocerca (6.5%) account for the largest fractions of the rotifer coenosis. The most species- rich samples are from habitats in, the floodplain of River Sepik. These results confirm the importance of tropical floodplain systems as optimal habitats for Rotifera (2).(2) H.
