Taxonomy and history
Actinonaias was first described as a subgenus of Unio in 1894 by Joseph Charles Hippolyte Crosse and Paul Henri Fischer, with Unio sapotalensis as the type species.[1][2] The name Actinonaias is derived from the Greek words άκτίν, meaning "ray", and ναϊάς, meaning "naiad".[2]
The genus is now placed within the subfamily Ambleminae and tribe Lampsilini. Seven species are currently recognised.[1][3]
