ABSTRACT Three new species of Luticola are described from lotic ecosystems in Andakí Municipal Natural Park, located in the Andean-Amazon region on the eastern flank of the eastern Andes mountain range in Colombia. Size and morphological features of the three new species, L. caquetensis Kociolek, Simonato & Núñez-Avellaneda sp. nov., L. andakiesiorum Simonato, Kociolek & Plata Díaz sp. nov., and L. sinchii Sala, Kociolek & Simonato sp. nov. are provided, based on light and scanning electron microscopical observations, and compared with similar congeners. Species of the genus are organized into groups depending upon whether they possess or lack marginal channels and/or pseudosepta. All the new species possess pseudosepta and L. caquetensis and L. andakiesiorum lack marginal channels. The two latter species share this combination of features with Luticola affinis Levkov et al., a species described from Brazil. These species thus form a unique group within the genus, offering additional evidence for the unique biodiversity found in this region.

来自哥伦比亚安第斯-亚马逊河流域的三个新 Luticola 物种：该属生物地理学的分类学、形态学和初步考虑

摘要 从位于哥伦比亚安第斯山脉东侧安第斯-亚马逊地区的安达基市自然公园的 Lotic 生态系统中描述了三个新的 Luticola 物种。三个新物种 L. caquetensis Kociolek、Simonato 和 Núñez-Avellaneda sp. 的大小和形态特征。11 月，L. andakiesiorum Simonato、Kociolek 和 Plata Díaz sp。11 月和 L. sinchii Sala、Kociolek 和 Simonato sp。十一月 提供了基于光和扫描电子显微观察的结果，并与类似的同类物进行了比较。该属的物种根据它们是否拥有或缺乏边缘通道和/或假隔而组织成组。所有新种都具有假隔壁，L. caquetensis 和 L. andakiesiorum 缺乏边缘通道。后两个物种与 Luticola affinis Levkov 等人（从巴西描述的物种）共享这种特征组合。因此，这些物种在该属内形成了一个独特的群体，为该地区发现的独特生物多样性提供了额外的证据。
