Abstract

Chromosome studies were performed on 40 specimens identified as Cebus apella paraguayanus, Fischer, 1829, which had been wild-caught in Santa Catalina (Republic of Paraguay). Elongated chromosome spreads obtained from lymphocyte cultures were sequentially stained with different techniques, and a constant pattern of 382 bands was identified in all specimens. A standard karyotype based on the measurements of the total chromosome length and the G-Q banding pattern is proposed.
