The Parsimony Analysis of Endemicity (PAE) is a method of historical biogeography that is used for detecting and connecting areas of endemism. Based on data on the distribution of Neotropical primates, we constructed matrices using quadrats, interfluvial regions and pre-determinated areas of endemism described for avians as Operative Geographic Units (OGUs). We codified the absence of a species from an OGU as 0 (zero) and its presence as 1 (one). A hypothetical area with a complete absence of primate species was used as outgroup to root the trees. All three analyses resulted in similar groupings of areas of endemism, which match the distribution of biomes in the Neotropical region. One area includes Central America and the extreme Northwest of South America, other the Amazon basin, and another the Atlantic Forest, Caatinga, Cerrado and Chaco.
特有性简约分析（PAE）是一种历史生物地理学方法，用于检测和连接特有区域。基于新热带灵长类动物分布的数据，我们使用样方、河间地区以及为鸟类描述的预先确定的特有区域作为操作地理单元（OGU）构建矩阵。我们将一个OGU中某物种的缺失编码为0（零），其存在编码为1（一）。一个完全没有灵长类物种的假设区域被用作外类群来给树状图定根。所有这三种分析都得出了相似的特有区域分组，这与新热带地区生物群落的分布相匹配。一个区域包括中美洲和南美洲最西北部，另一个是亚马逊盆地，还有一个是大西洋森林、卡廷加、塞拉多和查科。
