Abstract

Chinchillula sahamae Thomas, 1898 is a sigmodontine rat, known to occur in southern Peru, northern Chile, and western Bolivia. In this study, we report new records of the species in the departments of Huancavelica and Junín, Peru, which extend this species’ known distribution 370 km northwest, and new records in the department of Tacna, which extend the upper elevational range of the species to 5100 m, 250 m higher than previously known. In addition, we include notes on natural history, especially nesting behaviour, based on direct observations.

1898年在秘鲁中部发现的沙哈梅·托马斯(啮齿目，斑齿目)的显著范围扩展，附自然史注释

Chinchillula sahamae Thomas，1898是一种sigmodontine鼠，已知分布于秘鲁南部、智利北部和玻利维亚西部。在这项研究中，我们报告了秘鲁Huancavelica和Junín省的新物种记录，这些记录将该物种的已知分布向西北方向延伸了370公里，以及Tacna省的新记录，这些新记录将该种群的高海拔范围延伸到5100米，比之前已知的高250米。此外，我们还根据直接观察结果，对自然历史，特别是筑巢行为进行了注释。

期刊介绍： Check List is a peer-reviewed online journal, devoted to publishing biodiversity data related to species’ geographic distribution. Thus, our primary mission if to fill the so-called Wallacean shortfall (Lomolino 2004) and to improve our knowledge of how life is distributed on the planet in order to better preserve it. These data are essential for studies on biogeography and provide a baseline for the conservation of biodiversity. The first step to undertaking effective conservation action is to maintain records of the distribution of species. Therefore, the journal was created from the need publish basic data on species distribution of any taxon in a timely and open manner, which are often neglected by traditional journals. Check List is a bimonthly peer-reviewed online journal, and will consider for publication: -distribution summaries of a supraspecific taxon in a broad geographic area (e.g., hemisphere, country, biome), as a review of the distribution of a taxon in the given area. -annotated list of species, of a given taxon in a strict geographic area, with comments and illustrations on the identifications, based on original data. -notes on the geographic distribution, reporting new records of one or more species while providing a complete overview on the known distribution of the treated taxa. -book reviews on books related to biodiversity, biogeography, niche modeling, or any associated field that uses species distribution as its primary data source. -opinions on relevant subjects for the journal’s mission and scope
