Valvata piscinalis var. parthenopaea Bellini, 1904d: 42

Type locality: Sebeto river (Naples, Italy) .

Original description: “more elongated ovoid aperture; chamferings less deep; reddish yellow color with horny lustre”—with respect to Valvata piscinalis (Müller, 1774), reported as Valvata piscinalis Müller.

Remarks: having been instituted as a geographic race, we rank it subspecific, and thus available (ICZN 2012: Art. 10, glossary). Reported by Fasulo (2013) as a synonym of Valvata piscinalis (Müller, 1774) . This taxon was not figured by Bellini (1904d, 1915); however, taking into account the absence of congeneric and/or similar species from the Naples area (Welter-Schultes 2012), as well as the fact that it is generally a very common species, we are prone to accept that it was truly described as based on V. piscinalis . This taxon was not found during samplings held in the area in the 1980’s (Battaglini & Valentino 1981 –1982), and therefore it presumably did not survive the anthropogenic changes to which the Sebeto River has been subjected in the last century.
