| English abstract | Abstract Cytogenetic data can be useful for taxonomic and phylogenetic studies, as well as to provide information about chromosome evolution. Therefore, it may help design conservation priorities for some threatened species, such as anurans. Herein, we describe the karyotypes ofScinax constrictusandOlolygon centralis, native endemic species fromthe Brazilian Cerrado. Chromosome preparations for both species were stained with Giemsa for morphological analyses and then impregnated by the Ag-NOR method for localization of the nucleolar organizer region (NOR). Bothspecies had 24 chromosomes, as confirmed by meiotic analyses, which showed 12 bivalents. Chromosomemorphologies presented the same pattern forScinaxandOlolygoncompared to species already karyotyped in bothgenera. The NOR was interstitially located in the long arm of pair 7 inS. constrictus, whereas in O. centralisit wasfound near the centromere in the long arm of pair 1, thus diverging from what is commonly found for other Ololygon species. Therefore, we provide the first description of the karyotype ofO. centralisand the first report of the localization of the NOR for the karyotype of both species. Our study increases the cytogenetic knowledge in species of the genera Scinax and Ololygon, and provide support for further studies on the taxonomy, ecology, and evolution of hylid anurans |
