Oppenheim introduced the name clearly for the misidentified record of  Melania costatasensu Neumayr in Neumayr & Paul, 1875 (p. 41), non Olivier, 1804 from Slavonia, despite referring about Greek material. Later, however, he considered the name as rectification also for  Melania costatasensu Fuchs, 1877 from Megara and sensu Tournouer, 1876 from Kos Island ( Oppenheim 1891: 465). This fact remained unnoticed by Wenz (1929: 2808), who treated  Melanopsis pseudocostataas replacementname of the latter two records (Fuchs, Tournouer) but not of Neumayr and Paul'sspecies. In addition, there are three other new names proposed for misidentified  Melania costatafrom the Pliocene of Slavonia, i.e.,  Melanopsis croaticaBrusina, 1884 (for  Melania costatasensu Neumayr, 1869),  Melanopsis cosmanniPallary, 1916 [=  cossmanni, just. emend.] (for  Melania costatasensu Cossmann, 1909) and  Melanopsis permutabilisPallary, 1920 (for  Melania costatasensu Brusina, 1874). Note that Wenz (1929)erroneously considered  Melanopsis cosmannia replacement name of  Neumayr's(1869)record. Wenz obviously considered all erroneous "  Melania costata" records from Slavonia to represent the same species and synonymized them with  Melanopsis cosmanni, but was unaware that  Melanopsis croaticaBrusina, 1884 is the first available name for them. Although the four names (  croatica,  pseudocostata,  cosmanni,  permutabilis) likely refer to the very same species they are based on different specimens and thus no objective synonyms. For the record by  Tournouer(1876)from Kos Island, Pallary (1929: 119) introduced  Melanopsis sculptilisas replacement name. The misidentified  Melanopsis costatasensu Fuchs, 1877 from Megara, however, is still nameless. The name " pseudodecorata" mentioned by Cossmann (1909: 178) is an incorrect subsequent spelling.
