Present Inaccurate Introduced: alien Containing type locality
From editor or global species database
Type species Three different type species designations are available (Helix citrina by Martens, 1860 in Albers & Martens (1860: XII); Helix stuartiae by Kobelt, 1880: 215; Helix citrina by Fischer, 1883: 461), the earliest and therefore valid is the one of Martens (1860) [details]
