The Pyramidellidae (Gastropoda, Heterobranchia) of Norway and adjacent waters. A taxonomic review

Abstract

This monograph gives a taxonomic treatment of all 54 ‘species’ of Pyramidellidae reported from Norwegian and adjacent waters. Two species, Parthenina wikanderi n.sp.and Eulimella frielei n.sp., are described as new and three are ‘resurrected’ from synonymy. Nine previously described species are reported as new records for Norway, while three species are removed from the Norwegian fauna list. All species are illustrated with LM photographs (and, in a few cases, SEM photographs), and drawings of soft parts and operculae when available. An attempt is made to upgrade the generic taxonomy of the species included.

Redescription and reassignment of Ondina semicingulata to the Pyramidellidae, with review of the occurrence of genus Evalea in the Western Atlantic (Gastropoda)

“…Remarks. Except for the features of soft parts, absent in the type specimens of Acteon semicingulatus, all characteristics agree with the diagnose provided by Høisaeter (2014) for Ondina, including the oblong-ovate shell, oblong aperture and intorted protoconch. In comparison to the Eastern Atlantic species, which usually have more elongate shells, O. semicingulata has a wider shell, with biconical general shape.…”

“…Ondina striata was originally described as belonging to Aclis due to its spiral striae and was later transferred to the Pyramidellidae genus Odostomia (Menestho) by Bartsch (1911: 435) without any comments on this taxonomic rearrangement. The species has all features that characterize the genus Ondina (Høisaeter 2014) and is very similar to the type species of the genus. (Bartsch, 1909), comb.…”

“…Taxonomic identification of the new material from Brazil was based on conchological comparison with type specimens and with the recent revision by Høisaeter (2014). All available material consists of dry shells; in the "Examined material" the number of shells is indicated between brackets.…”

“…Taxonomic stud-scribed in a series of papers (e.g. van Aartsen 1987, van Aartsen et al 1996, Peñas et al 1996, Peñas and Rolán 1999, Warén 1991, Høisaeter 2014.…”

Early Miocene Gastropods from the Felli Section (Proto-Mediterranean Sea, NW Greece)

“…Due to the few shell characters of the genus, species belonging to Brachystomia Monterosato, 1884 have been included in Ondina de Folin, 1870 and Auristomia Monterosato, 1884 used as genera or subgenera(Lozouet et al 2001;Høisaeter 2014).…”
