The genus Akodon is one of the most species-rich rodent lineages in South America. In Peru, this genus contains 14 species subdivided in two groups: aerosus and boliviensis. Akodon orophilus Osgood, 1913 (Rodentia: Cricetidae) is a member of the Akodon aerosus group that inhabits the northern Peruvian montane forest, but is poorly characterized and its distribution is vaguely known. We review the status of the species based on morphology, morphometric and karyology, and compared with all members of the Akodon aerosus clade from Peruvian montane forests. As a result, we provide a complete redescription of A. orophilus, present new information on its natural history, restrict its distribution to the east of Río Marai6n, and describe a new species of Akodon from Huánuco Department, central Peru, a population previously assigned to A. orophilus.
阿氏鼠属是南美洲物种最为丰富的啮齿动物谱系之一。在秘鲁，该属包含14个物种，分为两组：埃氏阿氏鼠组和气氏阿氏鼠组。奥氏阿氏鼠（Akodon orophilus Osgood，1913年）（啮齿目：仓鼠科）是栖息在秘鲁北部山地森林的埃氏阿氏鼠组的成员，但特征描述不足，其分布也不太清楚。我们基于形态学、形态测量学和核型分析对该物种的状况进行了综述，并与秘鲁山地森林中埃氏阿氏鼠分支的所有成员进行了比较。结果，我们对奥氏阿氏鼠进行了完整重新描述，提供了其自然史的新信息，将其分布范围限定在马拉尼翁河以东，并描述了一种来自秘鲁中部瓦努科省的新阿氏鼠物种，该种群之前被归为奥氏阿氏鼠。
