Abstract

VILAMIU, Rossana de Paula et al. The karyotype of Noctilio Albiventris (Chiroptera, Octilionidae) from the northern pantanal of Brazil and its taxonomic implications. Mastozool. neotrop. [online]. 2010, vol.17, n.1, pp.219-224. ISSN 0327-9383.

The complete karyotype of Noctilio albiventris cabrerai is described on the basis of specimens from the northern Pantanal region of central Brazil. The G-banded karyotype comprises a diploid number (2n) of 34, an autosomal fundamental number (FNa) of 62, and respectively submetacentric and acrocentric X and Y chromosomes. Active nucleolar organizer regions (NORs) were located in pair 12. C-banding showed constitutive heterochromatin in the pericentromeric regions of all autosomes and in the X chromosome. Differences were found with respect to specimens from Honduras, referable to N. a. minor, which had a pair of autosomes with totally heterochromatic short arms, and from Colombia, referable to N. a. affinis, which had a metacentric X chromosome.

Keywords : G- and C-banding; Lesser bulldog bat; Nucleolar organizer regions; Pantanal.
