Global diversity of dipteran families (Insecta Diptera) in freshwater (excluding Simulidae, Culicidae, Chironomidae, Tipulidae and Tabanidae)

Abstract

Today's knowledge of worldwide species diversity of 19 families of aquatic Diptera in Continental Waters is presented. Nevertheless, we have to face for certain in most groups a restricted knowledge about distribution, ecology and systematic, particularly in the tropical environments. At the same time we realize a dramatically decline or even lack of specialists being able, having the time or the opportunity to extend or even secure the present information. The respective families with approximate numbers of aquatic species are: Blephariceridae (308), Deuterophlebiidae (14), Nyphomyiidae (7), Psychodidae (∼2.000), Scatopsidae (∼5), Tanyderidae (41), Ptychopteridae (69), Dixidae (173), Corethrellidae (97), Chaoboridae (∼50), Thaumaleidae (∼170), Ceratopogonidae (∼6.000), Stratiomyidae (∼43), Empididae (∼660), Lonchopteridae (2), Syrphidae (∼1.080), Sciomyzidae (∼190), Ephydridae (∼1.500), Muscidae (∼870). Numbers of aquatic species will surely increase with increased ecological and taxonomical efforts.

Distribution of Aquatic Diptera larvae of Yeşilırmak River (Turkey) and ecological characteristics

“…The family Dixidae with only two genera, Dixa and Dixella, is one of the smallest families of Diptera in Palearctic Region. They predominate in clean waters and headwater sites (Ivković and Ivanković, 2019;Wagner et al, 2008). In this study, Dixa sp.…”

“…They prefer mostly betamesosaprobic habitats, but they also found in oligosaprobic and alphamesosaprobic habitats. The family Dolichopodidae has wide range of stream zonation preferences from crenon to metapotamon (Tachet et al, 2010;Wagner et al, 2008). The individuals of this family were more common in Site 3 and 33.…”

“…Some taxa are very sensitive and cannot tolerate water pollution, while some taxa are extremely tolerant and survive in heavily polluted water (Adler and Courtney, 2019;Bouchard, 2004;Kazancı and Ertunç, 2010;Luoto, 2011). However, there are limited studies about the larval ecology of most Diptera species in the world (Wagner et al, 2008).…”

Colonización de macroinvertebrados acuáticos en tres tipos de sustratos artificiales, en un río tropical

“…Los sustratos artificiales se colonizaron por una variedad de familias y géneros, sin embargo, la familia más abundante fue Chironomidae. Algunos representantes de la familia Chironomidae se caracterizan por la capacidad de establecerse en una gran variedad de hábitats y en distintas condiciones de la calidad del agua y entorno (Griffith, Kaufmann, Herlihy, & Hill, 2001;Hedrick et al, 2010;Silva, Ruiz, Bochini, & Moreira, 2008;Wagner et al, 2008). Similarmente, el género Tricorythodes sp.…”

How to inventory tropical flies (Diptera)—One of the megadiverse orders of insects

“…Only the Coleoptera share a diverse ecological repertoire with the Diptera, although beetles have no vertebrate parasites or haematophagous species. Also, with 12,700 aquatic species (Jäch & Balke 2008), beetles are not as diverse in freshwater habitats as are, at a minimum, the 39,000 aquatic species of Diptera (as calculated from Borkent 2012, Pape et al 2011, Wagner et al 2008.…”
