Actinonaias is a genus of freshwater mussels in the family Unionidae.

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]

  • Actinonaias moctezumensis (Pilsbry, 1910)
  • Actinonaias sapotalensis (Lea, 1841)
