Three new species of Mycetophilidae - Cordyla monticola sp. n., Cordyla pseudopusilla sp. n. and Cordyla reducta sp. n. - are described from the Colombian Andes, representing the first described species of Cordyla Meigen from the Neotropical region. Colour photos of their habitus, wing and terminalia are provided. The morphological affinities of male terminalia are discussed in a worldwide context. The distributional pattern of the genus clearly indicates a case of northern elements reaching the north-western region of the Neotropics that corresponds to a secondary extension of a Holarctic clade to the south.

本文描述了菌蚊科的三个新物种——山地柯迪菌蚊Cordyla monticola sp. n.、拟小柯迪菌蚊Cordyla pseudopusilla sp. n. 和缩减柯迪菌蚊Cordyla reducta sp. n.，它们来自哥伦比亚安第斯山脉，是新热带地区首次描述的柯迪菌蚊属物种。文中提供了它们的成虫、翅和尾器的彩色照片。在全球范围内讨论了雄性尾器的形态亲缘关系。该属的分布模式清楚地表明了一种北方类群到达新热带地区西北部的情况，这相当于全北区一个分支向南方的次生扩展。
