A lectotype for the stabilization of the name Chama magna da Costa, 1778 (presently Lutraria magna (da Costa, 1778); Bivalvia: Mactridae)

Abstract

Chama magna da Costa, 1778, currently belonging to the genus Lutraria, has been considered a synonym of Lutraria lutraria, or a species of its own. It is here argued that the original description and figure is based on a species that is not conspecific with L. lutraria, but that the references accompanying the description partially refer to L. lutraria. To end this unwanted situation, the original figure is selected as the lectotype of Chama magna. By doing so, the name is stabilized and Mya oblonga Gmelin, 1791 becomes a junior synonym of L. magna (da Costa, 1778).

Pododesmus subrugosus (A. d’Orbigny, 1852) (Bivalvia: Anomiidae) from the Pliocene of the North Sea Basin

Abstract

In 1845, P.H. Nyst described the species Anomia? rugosa from Pliocene deposits of Belgium. This common Pliocene North Sea Basin taxon is currently attributed to the extant species Pododesmus patelliformis (Linnaeus, 1761). However, the Pliocene species is different from the extant species and hence reintroduced here under its valid name Pododesmus subrugosus (A. d’Orbigny, 1852). A lectotype is designated.

Abstract

One of the syntypes of Strombus robustus G.B. Sowerby III, 1875 has been discovered in the collection of NHMUK and is designated as lectotype. The status of this species, allocated to Margistrombus Bandel, 2007, is addressed. Both Strom­bus (Dolomena) marginatus sowerbyorum Visser & Man in ’t Veld, 2005 and Margistrombus bouchet Thach, 2016 are junior subjective synonyms of S. robustus. The lectotype of S. robustus and the holotype of respectively S. (D.) m. sow­erbyorum and M. boucheti is illustrated.

The identity of Meioceras elongatum de Folin, 1881 (Gastropoda, Caenogastropoda, Caecidae)

Abstract

Meioceras elongatum de Folin, 1881, has been described from “mers de Chine” (China Seas) and was never recorded thereafter. The three syntypes are not conspecific and have probably a different origin. To stabilize the nomenclature, the specimen best fitting the original description and illus­tration is here selected as lectotype. As a consequence, Mei­oceras elongatum has to be considered a junior synonym of M. nitidum (Stimpson, 1851).
