Analetris
Analetris is a genus of sand-dwelling mayflies in the family Acanthametropodidae, established by Edmunds in 1972. The genus contains at least two species: the extant Analetris eximia and the extinct †Analetris secundus. Members of this genus are specialized inhabitants of riverine environments with unstable silty substrates. The best-studied species, A. eximia, is considered endangered due to habitat destruction from reservoir construction.
