ABSTRACT Newly available molecular sequences and morphological data suggest that Philander nigratus Thomas, 1923, is a valid species. Currently known from just eight specimens collected in the Peruvian departments of Junín and Ayacucho, P. nigratus does not appear to be closely related to either of the congeneric taxa with which it was previously synonymized.

Philander (Marsupialia: Didelphidae) 的修订版，第 2 部分：P. nigratus Thomas 的系统发育关系和形态学诊断，1923

摘要 新获得的分子序列和形态学数据表明，Philander nigratus Thomas, 1923 是一个有效的物种。目前仅从秘鲁胡宁省和阿亚库乔省收集的 8 个标本中得知，P. nigratus 似乎与其之前同义的同类分类群中的任何一个都没有密切关系。
