Taxon classification Animalia ORDO FAMILIA

Planorbarius halavatsi nom. n.

Planorbis grandis Halaváts, 1903: 57, pl. 3, fig. 5 [non Planorbis grandis Dunker in Küster et al., 1850].

Coretus grandis ( Halaváts); Wenz 1923c: 1472 [non Dunker in Küster et al. 1850].

Planorbarius grandis ( Halaváts); Sauerzopf 1953: 50, pl. 1, figs 3-4 [non Dunker in Küster et al. 1850].

Etymology.

In honor of Gyula von Halaváts (Budapest), who greatly contributed to our knowledge of Pannonian mollusks.

Type locality.

Balatonfőkajár, Veszprém, Hungary.

Age.

Late Miocene (Late Pannonian,?Transdanubian sensu Sacchi and Horváth 2002).

Holotype.

Hungarian Geological Institute, Budapest, coll. no. Pl. 121 (Boda 1964, p. 130).

Discussion.

As both taxa were introduced within Planorbis, the species described by Halaváts is a primary homonym. Both are today unambiguously assigned to the genus Planorbarius (for the Pannonian species see, e.g., Sauerzopf 1953, Harzhauser and Tempfer 2004) and are in common usage, making the introduction of a replacement name indispensable. Planorbis grandis Dunker in Küster et al., 1850, an extant taxon from SE Europe, is currently ranked as subspecies of Planorbis corneus (see Fauna Europaea project, De Jong 2013).
