Theodoxus ( Theodoxus ) dacicus Pană 2003: 301 , pl. 1, figs 7–8 [non Theodoxus dacicus Jekelius, 1944 ]. Etymology. To denote that this species is not Theodoxus dacicus . Type locality. Vintilă Vodă in Slănic valley, Buzău , Romania . Age. Lower Romanian (= Sienisian, upper Zanclean). Holotype . Laboratory of Paleontology , Bucharest , coll. no. 623, L. P. B. III g. Discussion. This species was introduced by Pană (2003) for a Pliocene taxon from the Dacian Basin. It is a primary homonym of Theodoxus dacicus Jekelius, 1944 (p. 114), a different species described from the Late Miocene of Soceni in the Pannonian Basin. The Miocene species was classified by Papp (1953 , p. 99) as a subspecies of T. leobersdorfensis ( Handmann, 1887 ) . When introducing this species Pană (2003) referred to it as " Theodoxus (Theodoxus) dacicus n. sp. Pană 1989 ". This leads to some confusion, since she properly described and illustrated the taxon and indicated a holotype in 2003, but gave no reference to a work from 1989. The only publication from Pană (1989) known to us deals with different taxa. Maybe she introduced the name (as nomen nudum ) in an unpublished thesis.
