Ampullaria erronea Nevill, 1877. Cat. Moll. Ind. Mus. Fasc. E: 17.

Current taxonomic status.

Pomacea erronea (Nevill, 1877), valid species.

Type locality.

"South America"; collector unknown.

Type material.

Holotype (by original designation): NZSI M.2404 (registered 8 January 1894).

Shell dimensions.

Holotype: SH 28.4 mm, SW 24.9 mm, AH 19.1 mm, AW 14.8 mm, OH 16.1 mm, OW 10.5 mm.

Remarks.

Nevill (1877: 17) suggested the name erronea for this South American species, which Reeve had previously misidentified as aperta Philippi. Nevill considered it readily distinguishable from aperta. He stated that the “Type” of Ampullaria erronea was in the Indian Museum. The dimensions of the present specimen closely match those given by Nevill for the “Type” and we consider it to be the holotype.
