The genus Callicebus has 28 species arranged in five groups: donacophilus, torquatus, moloch, cupreus and personatus. The personatus group occurs in the Brazilian Atlantic forests where it is isolated from the other Callicebus groups. The present pap

Meiotic analyses of the sex chromosomes were made in two different species belonging to the subfamily Carollinae (Phyllostomidae, Chiroptera): Rhinophylla pumilio and Carollia perspicillata. These species have different sex chromosome systems. Throug

Sex-autosome translocations are found in Chiroptera of the Phyllostomidae, leading to multiple XY1Y2 and composite neo-XY systems of chromosomal sex determination. We compared the behaviour of the ...

The karyotypes of Phyllostomus discolor and P. hastatus from Eastern Amazonia were studied by G-, C-, G/C sequential and Ag-NOR techniques. Both species presented 2n = 32, with the autosome complement composed of 30 bi-armed in P. discolor and 28 bi-

The current classification of genus Aotus includes nine species, four of which occur above the Amazon River and five below it. The position of several of these taxa as a valid species has been questioned. Recently, we described the chromosomal consti

The chromosomes of 22 animals of four subspecies of the genus Ateles (A. paniscus paniscus, A. p. chamek, A. belzebuth hybridus, and A. b. marginatus) were compared using G/C banding and NOR (nucleolar organizer region) staining methods. The cytogene
