Abstract

A neonate male owl monkey (Aotus sp.) was identified cytogenetically as a hybrid after it failed to nurse and died. Phenotypically, the male parent possessed characteristics of the "gray-neck group," and G-banded karyotypes identified him as Aotus lemurinus griseimembra (2n = 53). heterozygous for the centric fusion of chromosomes 13 and 14. The female parent belonged to the "red-neck group" and was identified cytogenetically as Aotus nancymaae (2n = 54) The neonate hybrid had 2n 54 chromosomes with 13 homologous pairsof autosomes, 26 nonhomologous autosomes, and XY sex chromosomes. Thirteenof the nonhomologous chromosomes represented the paternal complement, and 13 were from the maternal complement. Chromosomal rearrangements occurring between the karyotypes of A. i. griseimembra and A. nancymaae were believedto include two paracentric inversions. a reciprocal translocation. and twocomplex rearrangements involving pericentric inversion, telocentromeric fusion, and centromeric adjustment. Cytogenetic analyses are necessary to identify most Aotus taxa and thus should be utilized to pair chromosomally compatible animals and avoid interspecies hybridization.
