摘要

Two freshwater mussel species thought to have been extirpated from Arkansas have recently been rediscovered in the Ouachita River in the vicinity of Camden. Prior to this survey, Wheeler (1918) last reported Arkansia wheeleri Ortmann and Walker, the Ouachita rock-pocketbook, and Cumberlandia monodonta (Say), the spectaclecase, from the Ouachita River near Arkadelphia. Quadrula apiculata (Lea), the southern mapleleaf, has been reported from Arkansas on two occasions, but due to taxonomic uncertainty, it has not been recognized in recent compilations of Arkansas freshwater mussels. During this survey, the southern mapleleaf was collected from the Ouachita River which verifies its occurrence within Arkansas. Quadrula fragosa (Conrad), the winged mapleleaf, is reported as a new state record. Arkansia wheeleri and Quadrula fragosa are listed as threatened and endangered species, respectively, by the U.S. Fish and Wildlife Service.
