摘要	The karyotypes of three species (N. coucang, N. intermedius, and N. pygmaeus) of genus Nycticebus, collected from the southern Yunnan of China, have been studied. All individuals from three species possess 2n=50 chromosomes, and all chromosomes in their complement are biarm chromosomes. The karyotype of slow loris (N. coucang) is characterized by having a secondary constriction and Ag-NORs in the short arms of pair No. 1. The G-banding patterns of three species are very similar. Three species are found to have multiple Ag-NORs. In N. coucang, NORs were observed on five pairs (Nos. 1, 6, 9, 15, and 23) and in N. intermedius and N. pygmaeus, NORs were found on four pairs (Nos. 6, 9, 15, and 20). This finding indicates that slow lorises, as primitive primates, also have multiple NOR-bearing chromosomes. Finally, the classification of genus Nycticebus by karyotype analysis is discussed, and our results suggest that there are at least two valid species, namely: N. coucang and N. pygmaeus.
