“…The diploid number (2n) of Lasiurus villosissimus is 28 chromosomes. The autosomes comprise 10 pairs of metacentric and submetacentric chromosomes ranging in size from large to medium (pairs 1–10), one pair of small subtelocentric chromosomes (pair 12), and two pairs of small acrocentric chromosome (11 and 13); the X chromosome is a medium submetacentric (Marchesin and Versute 2004).…”

The South American hoary bat, Lasiurus villosissimus (É. Geoffroy Saint-Hilaire, 1806), is a vespertilionid bat, endemic to South America and occurring in all countries except Guyana, French Guiana, and Suriname. It is one of the four species included in the subgenus Aeorestes. Lasiurus villosissimus is distinguishable from all other species of the genus by its larger size and coloration (except Lasiurus cinereus, but it only occurs in Mexico, Central America, and the Hawaiian Islands). Pelage is dark brownish and grayish mixed with yellow, tinged with white, producing a frosty or hoary appearance which is always evident. It is an insectivorous species that inhabits a great variety of habitats.

Histiotus magellanicus (Philippi, 1866) is a vespertilionid bat called the southern big-eared brown bat. The dark color of the ears and the absence of a connecting band between the ears are the characters that clearly differentiate this species from all other species of Histiotus. It is a little-known species with a distribution restricted to the southern portions of Argentina and Chile. H. magellanicus is listed as “Least Concern” by the International Union for Conservation of Nature and Natural Resources.

Dermanura Gervais, 1856 is represented by small frugivorous bats of the Stenodermatinae subfamily. The taxonomy of this group presents controversies and has been subject to changes, especially since the morphological characters evaluated have left gaps that are difficult to fill regarding good species characterization. Previous studies performed in Dermanura cinerea Gervais, 1856 found that the karyotype of this species has a diploid number of chromosomes equal to 30 and 56 autosomal arms. The objective of the present study was to describe, for the first time, the karyotypes of the species Dermanura anderseni (Osgood, 1916) and Dermanura gnoma (Handley, 1987) based on classical cytogenetic markers. For both species, the diploid number found was 2n = 30 and NFa = 56. Two pairs of chromosomes showed markings of the nucleolus organizing regions (AgNORs) in the species D. anderseni and only one pair in D. gnoma, differing from what has already been described for D. cinerea. The two species analyzed here also showed differences in the sex chromosome system, with D. gnoma showing a neo-XY type system while in D. anderseni the classic XY sexual system was observed. In both species, visualization of the constitutive heterochromatin occurred in the pericentromeric region of all chromosomes, as well as in the short arms of the subtelocentric chromosomes. The present work represents an important expansion of karyotypic information for the subfamily Stenodermatinae, bringing chromosomal features that are possible to use in the taxonomic implications of the group.
