Genus Tanytarsus Wulp, 1874

Syn.: Nimbocera Reiss, 1972 (see Sanseverino et al. 2010).

Syn.: Caladomyia Säwedal, 1981 (see Lin et al. 2018).

A species-rich genus with approximately 400 described extant species that occur in all zoogeographical regions except Antarctica, including 100 species known from the Neotropics (Dantas et al. 2022, 2023; Dantas & Giłka 2024). A molecular phylogeny of the genus was presented by Lin et al. (2018), placing Caladomyia as a junior synonym of Tanytarsus . The larvae are found in all types of freshwaters, with some marine, and at least one terrestrial species. The freshwater species usually construct long, soft tubes that are fixed to the bottom substrate (Epler et al. 2013).
