BURGOS, Eliana F et al. NEW RECORDS OF CALOMYS TENER (RODENTIA: CRICETIDAE, SIGMODONTINAE) THAT EXPAND THE DISTRIBUTION AND KNOWN GENETIC DIVERSITY FOR MISIONES, ARGENTINA. Mastozool. neotrop. [online]. 2022, vol.29, n.1, pp.654-654. Epub 14-Nov-2021. ISSN 0327-9383.
Misiones province has a great diversity of rodents, some of them, such as Calomys tener, have few records and their presence in the province has been widely discussed. The aims of this work were to: a) provide information on a new locality of presence, b) describe morphologically, and c) analyze the molecular variability of cytochrome b of Calomys tener. Based on sampling seasons carried out in 2017 and 2018, four individuals were captured and identified morphologically and molecularly as C. tener. This new records extend the species distribution to the north of the province of Misiones. The sequences of C. tener obtained in this study, together with those available in GenBank from Paraguay, Brazil, Bolivia and Argentina, show that the haplotypes found in Misiones are divergent, suggesting multiple colonization from different geographic areas.
