Neoempheria

fungus gnats

Species Guides

Neoempheria is a of fungus gnats in the Mycetophilidae, containing at least 140 described . The genus is particularly diverse in the Neotropical region, with 41 species recorded from Brazil. Larvae develop in association with fungi, making this one of the key groups of fungivorous insects. The first biological association between Neoempheria larvae and fungi in the Neotropical region was documented in 2015 for N. puncticoxa, marking a significant advance in understanding the natural history of this poorly studied group in South America.

Distribution

Neoempheria occurs in the Neotropical region, with 41 documented from Brazil. Records are predominantly from southern and southeastern Brazil, with the first Amazonian record (Pará state) documented for N. bilobata. The also occurs in Europe, with records from Denmark, Norway, and Sweden. At least 140 species are described globally.

Diet

Larvae feed on fungi. In shiitake mushroom systems, larvae have been observed developing in cultivated mushrooms.

Taxonomic significance

Neoempheria has been subject to recent taxonomic revision, with hidden diversity exposed through and re-examination of . The exemplifies how even relatively well-documented regions contain undiscovered , and how misidentifications can persist when type material is not critically examined.

Research priorities

Ongoing research focuses on linking different to specific mushroom , documenting complete for Neotropical species, and exploring the evolutionary relationships between fungus gnats and fungi over the last 145 million years.
