The family Lygistorrhinidae is comprised of a small group of mycetophiloid flies easily distinguished by their elongate mouthparts and considerably reduced wing venation. Specimens are uncommon in collections, but can be locally abundant in various warm areas of the globe.

Following the recent work of Matile (1990b), the family is composed of 4 genera (three living, one fossil). Two species of fossil lygistorrhinids are listed in this catalog.
