对来自巴西亚马逊多个地区的25个独特形态的僧面猴（此后称为僧面猴属某种，Chiropotes sp.）标本进行了形态学、核型和分子分析。毛色明显区分了所采集的标本与该属所有其他已知物种。描述了僧面猴属某种独特的核型。它与黑须僧面猴（C. satanas chiropotes）相比有两个臂间倒位的差异，与犹氏僧面猴（C. satanas utahicki）相比有三个差异，这表明这些分类群在生殖上是隔离的。形态测量分析未显示这些僧面猴分类群之间存在显著差异。分子分析证实了卷尾猴亚科以及僧面猴属、秃猴属和青猴属的单系性（青猴属似乎是卷尾猴类群中最基部的谱系）。犹氏僧面猴与来自内格罗河的僧面猴属某种之间的遗传距离大于青猴属三个公认物种之间的距离，但小于白秃猴（Cacajao caluus）和黑秃猴（Cacajao melanocephalus）之间的距离。来自内格罗河的僧面猴属某种最合适的名称是以色列僧面猴（C. israelita）。该物种、黑须僧面猴和犹氏僧面猴是异域分布的。毛色、核型和分子分析有力地表明黑须僧面猴、犹氏僧面猴和以色列僧面猴应具有物种地位。（C）2003威利 - 利斯公司
Morphologic, karyotypic, and molecular analyses were carried out in 25 specimens of a distinct morph of Chiropotes (henceforth termed Chiropotes sp.) obtained from a number of localities in the Brazilian Amazon. Pelage coloration clearly distinguishes the collected specimens and all other known species of this genus. A distinct karyotype was described for Chiropotes sp. It differs from C. satanas chiropotes by two pericentric inversions, and from C. satanas utahicki by three, which suggests that these taxa are reproductively isolated. Morphometric analyses did not show significant differentiation between these Chiropotes taxa. Molecular analyses confirmed the monophyly of the subfamily Pitheciinae and genera Chiropotes, Cacajao, and Pithecia (the latter appearing as the most basal lineage of the pithecine clade). The genetic distances between C. s. utahicki and Chiropotes sp. from Rio Negro were greater than those between three recognized species of Pithecia, but smaller than those between Cacajao caluus and Cacajao melanocephalus. The most appropriate name for Chiropotes sp. from Rio Negro is C. israelita. This species, C. s. chiropotes, and C. s. utahicki are allopatric. Pelage coloration, karyotype, and molecular analysis strongly indicate that C. chiropotes, C. utahichi, and Chiropotes israelita deserve species status. (C) 2003 Wiley-Liss, Inc.
