Fungus Gnat

This is a huge group of flies that I will group together and maybe try to sort out at a later stage. I got an identification for one of these rather small mosquito-like animals. ALA didn't produce any results and neither did GBIF for the taxon Sciaroidea. It is known to Wikipedia however. Also, there is a whole taxonomic database dedicated to this taxonomic group, solely dedicated to Fungus Gnats. Here is the link: http://sciaroidea.info/
