- Аннотация: Comparative morphological, karyological and electrophoretic analyses of 29 individuals of Nectomys squamipes from 4 different localities of Amazonia and an unsual specimen of water rat, captured on October 29, 1991 in primary rainforest, 7 km to the east of the village Henaro Errera on the right bank of the Ukayaly river, Requena province, Department Loreto, Peru (04-degrees-55' SL and 73-degrees-45' WL) were carried out. The single specimen was defined as belonging to a new genus and a new species (holotype N S-155533, male, deposited in the collection of the Zoological Museum of Moscow State University), Amphinectomys savamis Malygin sp. n. The monotypical genus differs from the genus Nectomys s. 1. by several external characters (the webbing on hind feet extends over all digital phalanges up to the claws), the pattern of pelage coloration, 8 quantitative and 10 qualitative cranial characters, karyotype (2n = 52; NF = 66) and by the electrophoretic mobility of 5 out of 14 enzymes. A table containing morphometric data on 5 external and 14 cranial measurements as well as the values of parietal index and the weight of a specimen of A. savamis and 22 adult and subadult individuals of N. squamipes is given. The single specimen of A. savamis was trapped in primary rainforest, approximately 5 km to the North - East of the spot, where 21 individuals of N. squamipes were caught. These two species inhabit different biotopes. The new species was found in the forest near a stream, whereas Nectomys spp. occur in open areas.
