There is a controversy regarding how many species the genus Lagothrix contains, since the Lagothrix lagothricha subspecies have been recently proposed to be actual species. Clarification of species status is of particular importance in the case of L. l. lugens, because it is the most endangered and its distribution is restricted to the Colombian Andes, a highly deforested region. Using cytogenetic and molecular markers, we obtained evidence indicating that the subspecies status is appropriate for the two taxa occurring in this country. We also report high levels of intraspecific variability in the karyotype. We find evidence for a late Pleistocene separation of the subspecies, and we propose it is the limited area of contact between the taxa that allowed for them to partially differentiate.
关于该属包含多少个物种存在争议，因为拉氏林狸的亚种最近被提议为实际物种。澄清物种状况在 L. l. lugens 的情况下尤为重要，因为它是最濒危的，其分布仅限于高度森林砍伐的哥伦比亚安第斯山脉。使用细胞遗传学和分子标记，我们获得了证据表明，这两个在该国出现的分类群的亚种地位是合适的。我们还报告了染色体组型中高度的种内变异性。我们发现了亚种在更新世晚期分离的证据，我们提出这是由于分类群之间接触面积有限，使它们能够部分分化。
