REMARKS

For an explanation of authorship of this species see comments on the original work by Cowie & Thiengo (2003: 94). Date of publication of the description is taken as the date of publication of the text, as given by Cowie & Thiengo (2003: 94), although the exact date of publication of the plate is not known. The shell in poorer condition corresponds well with the illustration in shape and in the pattern of spiral bands, but is a little smaller than the illustration. This shell is here designated as the lectotype to stabilise the name. The other shell corresponds well with Swainson’s (1823: pl. 143, figs 1, 2 [top and bottom figures]) figures of Ampullaria sordida Swainson, 1823 . Cowie & Thiengo (2003: 54) considered Ampullaria intermedia a synonym of Ampullaria sordida , which they listed in Pomacea (Pomacea) , yet they mistakenly listed Ampullaria intermedia in Pomacea (Effusa) , which was the generic assignment followed by Berthold (1991: 23) for this species. Hayes (2009: 99), based on molecular analysis, considered it a valid species sister to Ampullaria sordida .
