This work adds a new eyeless species of the genus Micranops Cameron, 1913 (Staphylinidae, Paederinae, Scopaeina) to the endogean Coleoptera of the Bolivian fauna. The loss of eyes is usually associated with adaptations to subterranean habitats, although M. bolivianus Guzman & Żyła sp. nov. was collected from leaf litter. We also report new occurrences for the genus west of the Andes mountain range. Our work increases the number of known Neotropical Micranops species to seven and extends the known distribution range for the genus in South America.

玻利维亚无眼小微型鸟 Cameron 1913 新种（鞘翅目：葡萄球菌科： Paederinae）

这项工作将 Micranops Cameron, 1913 属（Staphylinidae、Paederinae、Scopaeina）的新无眼物种添加到玻利维亚动物群的内生鞘翅目中。眼睛的丧失通常与对地下栖息地的适应有关，尽管 M. bolivianus Guzman & Żyła sp.十一月是从落叶中收集的。我们还报告了安第斯山脉以西该属的新发现。我们的工作将已知的新热带微型菌属物种的数量增加到七种，并扩大了该属在南美洲的已知分布范围。
