Patterns of molecular genetic differentiation among taxa of the "agassii species complex" (Parenti, 1984) were analysed based on partial mtDNA control region sequences. Special attention has been paid to Chilean populations of Orestias agassii and species from isolated lakes of northern Chile, e.g., O. agassii, Orestias chungarensis, Orestias parinacotensis, Orestias laucaensis, and Orestias ascotanensis. Orestias tschudii, Orestias luteus, and Orestias ispi were analysed comparatively. Our findings support the utility of mtDNA control region sequences for phylogenetic studies within the "agassii species complex" and confirmed the monophyly of this particular lineage, excluding O. luteus. However, the monophyly of further morphologically defined lineages within the "agassii complex" appears doubtful. No support was found for the utility of these data sets for inferring phylogenetic relationships between more distantly related taxa originating from Lake Titicaca.
基于部分线粒体DNA控制区序列，分析了“阿加西物种复合体”（帕伦蒂，1984年）各分类单元之间的分子遗传分化模式。特别关注了智利阿加西湖的奥雷提亚斯种群以及智利北部孤立湖泊中的物种，例如阿加西奥雷提亚斯、琼加雷奥雷提亚斯、帕里纳科特奥雷提亚斯、劳卡奥雷提亚斯和阿斯克托奥雷提亚斯。对丘氏奥雷提亚斯、黄斑奥雷提亚斯和伊斯皮奥雷提亚斯进行了比较分析。我们的研究结果支持线粒体DNA控制区序列在“阿加西物种复合体”系统发育研究中的实用性，并证实了该特定谱系的单系性，但不包括黄斑奥雷提亚斯。然而，“阿加西复合体”中进一步形态学定义的谱系的单系性似乎令人怀疑。没有发现这些数据集可用于推断源自的的喀喀湖的亲缘关系更远的分类单元之间的系统发育关系。
