Prometaphase lymphocyte chromosomes from eight adult argentinian Alouatta caraya females were characterized using sequential G‐C banding techniques, Ag‐NOR bands and bands obtained with the restriction enzymes Hae III, Eco RI, Alu I and Sau 3A. The cytogenetic analysis showed 2n = 52, with four, five, or six NOR chromosomes. Digestion with Hae III and Eco RI produced G‐like‐bands. Centromere regions and two interstitial C‐bands (in chromosomes number 16 and 21) showed intraindividual or interindividual heterochromatic polymorphisms. Alu I digestion produced C‐like bands with gaps in the centromere regions, and Sau 3A produced C‐like bands. The karyotypes and banding patterns of A. caraya , A. palliata , A. belzebul , and A. seniculus are compared, based on whole chromosome and whole arm homeologies. © 1994 Wiley‐Liss, Inc.
