“…1) is clearly different of the R. fi scherae from Colômbia (Baker, Bleier, 1971;Baker et al, 1987), with 2n=34 (20M/SM+4ST+6A with a very small pair of chromosomes) previously described by conventional analysis (sample from Leticia) and G-banding (sample from Villavicencio, Baker et al, 1987). Comparative G-banding analysis between the karyotypes of R. fi scherae from Villavicencio (Colombia) and from Juruti (Brazil) shows an extensive chromosomal reorganization remaining few chromosomes shared without rearrangement.…”

Abstract. The genus Rhinophylla Peters, 1865 (Carolliinae: Phyllostomidae) comprises three species: R. pumilio Peters, 1865, R. fi scherae Carter, 1966 and R. alethina Handley, 1966. Only the fi rst two species have been cytogenetically studied to date. Previous studies on specimens of Rhinophylla fi scherae from two populations from East of Andes (Colombia) showed the karyotype with 2n=34 and FN=56. In this paper, we report the results of cytogenetic analysis of six specimens of Rhinophylla fi scherae from Brazil. Probably chromosomal differences can be found among the populations because of the geographic distance. Metaphase chromosomes were obtained in the fi eld by direct extraction of bone marrow. The metaphases were analyzed by conventional staining, G-and C-banding, NOR-staining and FISH with telomeric probes. Rhinophylla fi scherae has 2n=38 and Fundamental Number FN=68, with small amounts of constitutive heterochromatin in the centromeric regions of the chromosomes and the long arm of pair 16. Fluorescence in situ hybridization using telomeric probes did not show any interstitial sequences. Hybridization with human 18S and 28S rDNA probes and silver staining revealed the presence of Nucleolar Organizer Regions at the long arms of pairs 16 and 18. The pattern of G-banding showed that this population had a huge chromosome variation compared with previous studies on specimens of Rhinophylla fi scherae. The chromosomal differences among populations that have been morphologically classifi ed as R. fi scherae suggest that this species should be considered a cryptic species complex, and that the populations from different geographical regions analyzed to date should be considered species of this complex, where the chromosomal rearrangements had key importance.

“…An alteration in the amount and distribution of heterochromatin has been considered one of the most common forms of chromosome evolution in mammals (Baker et al, 1987), as it influences the pairing of the homologues in mutation events and gene recombination events and consequently affects the speciation process (Robbins and Baker, 1981). Specifically for P. gr.…”
