Abstract

A definition of  Biomphalaria helophila (Orbigny,
1835) is presented, based on examination of the shell and
reproductive system of topotypic specimens and extended to a
number of samples from other localities. The following nominal
species and subspecies, collected from type localities, proved
junior synonyms of  B. helophila: Planorbis albicans
Pfeiffer, 1839; Planorbis dentatus Gould, 1844;
Planorbis dentiferus CB Adams, 1845; Planorbis
dentiferus edentatus CB Adams, 1851; Planorbis dentiens
Morelet, 1849; Planorbula dentiens edentula Fischer &
Crosse, 1880; Planorbis stagnicola Morelet, 1851; and
Tropicorbis shimeki FC Baker, 1945.

B. helophila was also identified in samples from Costa Rica, Guatemala, Haiti, Dominican Republic, Puerto Rico and Barbados.
