A new case of an Holarctic element in the Colombian Andes: first record of Cordyla Meigen (Diptera Mycetophilidae) from the Neotropical region

摘要

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.
