Comparative cytogenetics of the <i>Physalaemus gracilis</i> group (Anura, Leptodactylidae) with characterization of the karyotype of <i>Physalaemus evangelistai</i> Bokermann, 1967.

ABSTRACT: The anuran species group Physalaemus gracilis comprises six species, and variation in the location of nucleolus organizer regions (NORs) was observed across the four species that have been karyotyped to date. The NORs are located interstitially on chromosome 8 of P. carrizorum Cardozo et Pereyra, 2018, and P. lisei Braun et Braun, 1977, terminally on chromosome 8 of P. gracilis (Boulenger, 1883), and terminally on chromosome 10 of P. barrioi Bokermann, 1967. To contribute to the comparative analysis of this group, including the assessment of the hypothesis of homology among these NOR-bearing chromosomes, we described the karyotype of P. evangelistai Bokermann, 1967, and expanded the cytogenetic analyses of P. carrizorum, P. lisei, and
