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.
基于对典型标本的贝壳和生殖系统的检查,给出了嗜喜沼螺(Biomphalaria helophila,奥比尼,1835年)的定义,并将其扩展至来自其他地区的一些样本。从模式产地采集的以下命名物种和亚种被证明是嗜喜沼螺的次异名。1839年的白色扁卷螺(Planorbis albicans)、1844年的有齿扁卷螺(Planorbis dentatus)、1845年的具齿扁卷螺(Planorbis dentiferus)、1851年的无齿具齿扁卷螺(Planorbis dentiferus edentatus)、1849年的具齿扁卷螺(Planorbis dentiens)、1880年的无齿具齿小扁卷螺(Planorbula dentiens edentula)、1851年的静水扁卷螺(Planorbis stagnicola)以及1945年的岛沼螺(Tropicorbis shimeki)。在来自哥斯达黎加、危地马拉、海地、多米尼加共和国、波多黎各和巴巴多斯的样本中也鉴定出了嗜喜沼螺。
