REMARKS

Listed in error in Pomacea (Pomacea) by Cowie & Thiengo (2003: 63), as Pain (1960: 430) had synonymised it with Ampullaria cyclostoma Spix in Wagner, 1827, which they placed in Asolene . Cowie & Thiengo (2003: 47) considered Ampullaria cyclostoma a synonym of Helix platae . We here treat Ampullaria elegans as a synonym of Helix platae . There are no illustrations in the original description with which to compare these shells. Given the uncertain status of the taxonomy of this and similar species and the possibility of mixed-species lots that require detailed taxonomic research, we refrain from selecting a lectotype from these four lots and 14 specimens.
