Abstract The Ditomyiidae are a family belonging to the suborder Bibionomorpha, until now without records to Colombia. This work reports the first record of the genera Rhipidita and Calliceratomyia for the Colombian region. Key words: Bibionomorpha, Catalogue, Colombia, distribution
Introduction Ditomyiidae are a family of gnats in the suborder Bibionomorpha, with eight genera and more than 100 species described worldwide (Vockeroth 2009), except in the Afrotropical region. In the Neotropical region, four genera and 35 species are recorded (Munroe 1974, Papavero 1978; Amorim et al. 2002; Huerta & Amorim 2016), none of them known from Colombia. For the first time the genus Rhipidita Edwards was collected with two new species (Falaschi & Amorim, in prep.) and the genus Calliceratomyia Lane, with four new species (Falaschi et al., in prep.). Adults are found on vegetation in primary forests. As pointed out by Munroe (1974), the wood- or hard fungus-boring habits of the larvae make extremely difficult to study the life history of these organisms in detail. Immature stages of ditomyiids are currently known only for the Holarctic genera Symmerus Walker and Ditomyia Winnertz, and the Chilean-Australian genus Australosymmerus Freeman (Matile 1990). Larvae are associated with bracket fungus (Basidiomycota: Polyporaceae) in rotten wood (Munroe 1974), where they build their galleries. Ditomyiids are medium-size gnats (3.0-8.0 mm), and can be recognized by the following characters: postpronotum with one or more long bristles, veins M1+2 and M3+4 basally connected (m-cu), basal portion of M absent and R4 present, long, well over half the length of the apical part of R5, Sc weak and ending free.
