Cowie, Robert H. & Héros, Virginie, 2012, Annotated catalogue of the types of Ampullariidae (Mollusca, Gastropoda) in the Muséum national d’Histoire naturelle, Paris, with lectotype designations, Zoosystema 34 (4), pp. 793-824 : 808-810

neritoides d’Orbigny, 1835 , Ampullaria ( Fig. 5B )

Ampullaria neritoides d’Orbigny, 1835a: 31 [1838: 368, pl. 49, figs 1, 2].

CURRENT TAXONOMIC STATUS. — Pomella (Pomella) . Synonym of Ampullaria megastoma Sowerby, 1825 ( Cowie & Thiengo 2003: 78).

TYPE SPECIMENS. — Probable syntypes MNHN 4518 (1 spm), 4519 (2 spms).

TYPE LOCALITY. — “Rio Uruguay (republica Uruguayensi orientali)” [“Corrientes” ( MNHN 4518)].

REMARKS

The original description did not include an illustration. Subsequently,d’Orbigny published another description (d’Orbigny 1838: 368) followed by the associated illustrations (d’Orbigny 1838: pl. 49, figs 1, 2), of which the dates of publication were listed by Cowie & Thiengo (2003: 91). More than one specimen was implied in the later description.However,none of the three shells precisely matches the dimensions given in the original description, nor the illustration published subsequently, although the maximum height of the largest specimen (100.3 mm) is close to the value (99 mm) given in the original description.We therefore refrain from designating any of these specimens as a lectotype. Hayes (2009) and Hayes et al. (2009a, b) showed that this species groups phylogenetically among species of Pomacea , and that Pomella may not be a valid genus. We here refrain from making any formal taxonomic changes reflecting this likelihood.

nimbae Binder, 1963, Afropomus balanoideus ( Fig. 5C )

Afropomus balanoideus nimbae Binder, 1963: 13 , fig. 1. CURRENT TAXONOMIC STATUS. — Afropomus balanoideus .

Valid subspecies. TYPE SPECIMENS. — Lectotype (here designated) MNHN

4497; paralectotypes MNHN 4456 (1 spm), 4495 (5 spms, in alcohol), 4496 (1 spm), 4498 (1 spm) .

TYPE LOCALITY. — “Dans le Gouan” [ Republic of Guinea].

REMARKS

The specimen herein selected as the lectotype, to stabilise the name, is the shell on the left in figure 1 of the original description. There is a label with it that says “type” and another that says “78Ea”, which ties it to the locality “Dans le Gouan” on page 11 of the original description, thereby restricting the type locality.Other localities given in the description are “Mont Nimba” [in publication title], “Nimba”, “Zouguépo”, “Dyé-Yé”, “Gamboué, sur la piste de Zouguépo à Sérengbara”, “Yisoro, sur la piste de Zouguépo à Sérengbara”, “Dans le Ya”, “Camp des gardes” and “Niomouya”, all Republic of Guinea.
