Ampullaria martinezi Hidalgo, 1866: 345 , pl. 14, fig. 5.

CURRENT TAXONOMIC STATUS. — Pomacea (Pomacea) . Valid species.

TYPE SPECIMENS. — Lectotype (Fischer-Piette 1950: 68) MNHN 4608 ; paralectotype MNHN 4609 .

TYPE LOCALITY. — “Santa-Rosa, Reipublicae AEquatoris” [ Ecuador].

REMARKS

Fischer-Piette (1950: 68) indicated a “ holotype ”. We consider this to be a valid, though inadvertent, designation of a lectotype, as he unambiguously selected this particular specimen as the unique name-bearing type (ICZN 1999b: art. 74.5). The original description does not reveal that the taxon was based on more than one specimen, so the requirement (ICZN 1999b: second part of art. 74.5) that the author (i.e. Fischer-Piette [1950]) “explicitly indicated that he or she was selecting from the type series that particular specimen to serve as the name-bearing type” is not pertinent in this case. The other specimen mentioned by him (MNHN 4609) becomes a paralectotype. The lectotype is the shell in the original illustration, and the sizes of the two shells correspond to the sizes given by Fischer-Piette, confirming their identity.
