Atlantic Forest, in the eastern coast of Brazil, is a hotspot of biodiversity of mammals, and Parque Estadual da Serra do Mar (PESM) is the largest continuous area of this biome. Here, we characterized the karyotype composition of the small mammals from Santa Virgínia, a region in the northern part of PESM. Specimens were collected from July 2008 to September 2009. We identified 17 species (13 rodents and 4 marsupials) from which 7 exhibited species-specific karyotypes, illustrating the importance of karyotype information in cytotaxonomy. We report for first time the karyotype of Monodelphis scalops (Thomas, 1888) and two new records for PESM: Akodon montensis Thomas, 1913 and Brucepattersonius soricinus Hershkovitz, 1998. Cytogenetic polymorphisms were detected for some species trapped in the area. Our results show the importance of Santa Virgínia / PESM in addressing studies for the conservation of small mammal wildlife in the Atlantic Forest.
巴西东海岸的大西洋森林是哺乳动物生物多样性的热点地区，而滨海塞拉多国家公园（PESM）是该生物群落中最大的连续区域。在此，我们对来自滨海塞拉多国家公园北部地区圣维吉尼亚的小型哺乳动物的核型组成进行了表征。样本采集于2008年7月至2009年9月。我们鉴定出17个物种（13种啮齿动物和4种有袋动物），其中7种呈现出物种特异性核型，这说明了核型信息在细胞分类学中的重要性。我们首次报告了蒙氏侏袋貂（Thomas，1888）的核型，以及滨海塞拉多国家公园的两个新记录：山地稻鼠（Thomas，1913）和索氏布鲁鼠（Hershkovitz，1998）。在该地区捕获的一些物种中检测到了细胞遗传多态性。我们的结果表明，圣维吉尼亚/滨海塞拉多国家公园在开展大西洋森林小型哺乳动物野生动物保护研究方面具有重要意义。
