Abstract
We present evidence that Paludma Integra Say, 1821, an early described species of North American freshwater snail which has been previously placed in either of two families (Hydrobiidae, Vivipandae), is the hydrobud snail known as Cincinnatui cincm-natiensis (Anthony, 1840). We provide a description for this snail, which is the type species of the genusCincinnatia Pilsbry, 1891, and select a neotype to ensure nomenclatural stability. Features of genitaha (including a second female bursal duct which has not been recorded previously for members of the family Hydrobiidae) distinguish this species from all other members of the North American subfamily Nymphophilinae. At the present time, insufficient data are available to support allocation of other species to Cincinnatia Paludma ancmnaticnsis Anthony, 1840, Amnicola scarboroughi Tryon, 1870, Amnicola peracuta Pilsbry & Walker in Pilsbry, 1889, Amnicola judayi Baker, 1922, and Cincinnatia cmctnnatiensis chicagoensis Baker, 1930 are junior synonyms of Cincinnatia Integra (Say, 1821)Keywords
