Wicker ancylid
The wicker ancylid, ''Rhodacmea filosa'', is a species of small, air-breathing, freshwater snail or limpet, a pulmonate gastropod in the family Planorbidae.〔
''Rhodacmea filosa'' is the type species of the genus ''Rhodacmea''.〔
== Distribution ==
This species is endemic to the United States and was thought to be extinct,〔 until its rediscovery in 2011.〔Ó Foighil D., Li J., Lee T., Johnson P., Evans R. & Burch J. B. (2011). "Conservation Genetics of a Critically Endangered Limpet Genus and Rediscovery of an Extinct Species". ''PLoS ONE'' 6(5): e20496. .〕 It occurred in the Mobile River Basin rivers and their tributaries.〔 The type locality is the Black Warrior River, south of Blount Springs, Alabama.〔Conrad T. A. (1834). "New fresh-water shells of the United States, with coloured illustrations, and a monograph of the genus ''Anculotus'' of Say; also a synopsis of the American naiads". Judah Dobson, Philadelphia, 76 pp. (page 57 ).〕
Over the past 20 years, extensive surveys that included hundreds of collecting sites in the drainages of the Coosa River, Cahaba River and Black Warrior River (its type locality) had failed to find ''Rhodacmea filosa''.〔 However, it does still persist in a Choccolocco Creek, a Coosa River tributary. Morphometric and phylogenetic analyses confirm the taxonomic validity of this material.〔 Its survival in Choccolocco Creek is somewhat surprising, given the serious episodes of industrial pollution experienced by this watershed.〔
