Coelotanypus Kieffer 1913

Genus Coelotanypus Kieffer, 1913 A genus of ~20 described species that occur in the Neotropical, Nearctic, Afrotropical, and Australasian regions. A key to the males of the Neotropical species was given by Paggi & Zilli (2018). The larvae inhabit benthic sediments of lakes, including artificial impoundments, slow flowing reaches of rivers, and old riverbeds (Cranston & Epler 2013). The genus can be very abundant in Amazonian flood-plain lakes and in wetlands in southern Brazil (Fonseca Leal et al. 2004; Panatta et al. 2007).
