Etymology. In honor of Arjan de Leeuw (CASP, Cambridge), specialist for the stratigraphy of the Dacian Basin.

Age. Lower Dacian (= Getian, middle Zanclean).

Holotype. Institut de Géologie et Géophysique, Bucharest, coll. no. 17050.

Discussion. In this particular case the rule of "difference in spelling of generic names" (ICZN 1999, Article 57.5) applies: Vivipara as given by Stefanescu (1897) represents an incorrect subsequent spelling of Viviparus Montfort, 1810 (Melville & Smith 1987, p. 185). The species is thus a primary homonym of Viviparus muscelensis (Stefanescu, 1897) and needed a replacement name (see also Wenz 1928, p. 2345).
