Genus Zavrelimyia Fittkau, 1962
Syn.: Paramerina Fittkau, 1962.
Recently Silva & Ekrem (2016) formally placed the genus Paramerina Fittkau as a synonym of Zavrelimyia Fittkau. The genus now comprises ~50 named species that occur in all zoogeographical regions except Antarctica. Larvae of Zavrelimyia s. str. are, with few exceptions, more or less cold stenothermic and in temperate regions of the Holarctic primarily inhabitants of sandy or detritus rich sediments of springs and lentic habitats of stream sections close to springs. Larvae of Zavrelimyia (Paramerina) are eurythermic, living in a variety of standing waters of all sizes, but are also present in small lotic habitats including pools in rivers (Cranston & Epler 2013).
