摘要

Two new locations were documented for Leptoxis plicata (Plicate Rocksnail), listed as endangered by the US Fish and Wildlife Service in 1998. Plicate Rocksnail is endemic to the Black Warrior River system in Alabama and was thought to be restricted to 15 shoals in a 30-km reach of Locust Fork, all upstream of the US Highway 78 crossing. During a routine biological survey, Plicate Rocksnail was found at two additional shoals downstream of the Highway 78 crossing: one 3.5 km (87 degrees 01'00"W, 33 degrees 41'30"N) and the other 5.2 km (87 degrees 00'30"W, 33 degrees 39'20"N) downstream. The rocksnails were extremely abundant at each of these locations and varied in size from small, apparently young of the year, to large adults. These two new locations extend the intrabasin range of this species over 5 kin farther downstream than previously reported.
