Original description Zilch attributed the name to Sandberger [1875, Die Land- und Susswasser-Conchylien der Vorwelt: 958], who listed Anisopsis in a list of subgenera of Planorbis, but did not provide a description. In that list, Sandberger did not explicitly include any species, but he marked the stratigraphic occurrence of the subgenus as “middle to late Jurassic”; the fact that he indicated Anisopsis to be the only subgenus of Planorbis for this period may be seen as implying that he considered the middle to late Jurassic Planorbis species in his monograph as belonging to Anisopsis. This is the case for P. calculus Sandberger, 1870, P. loryi Coquand, 1856 and P. coquandianus de Loriol, 1865. Baker (1945: 94) designated P. calculus Sandberger, 1870 as type species. [details]
