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

Kurina O, Oliveira SS - Zookeys (2015)

Bottom Line: 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.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.

ABSTRACT
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.

Cordylamonticola sp. n., male terminalia. 3 ventral view 4 lateral view 5 dorsal view 6 sternite VIII, ventral view 7 hypoproct, ventral view. Scale bars: 0.1 mm (3, 4, 5, 6) and 0.05 mm (7). Abbreviations: cerc = cercus; epi = epiproct; gc = gonocoxite; gst d = dorsal branch of gonostylus; gst v = ventral branch of gonostylus; hyp = hypoproct; st VIII = sternite VIII.
