POTENTIAL SUBJECTIVE JUNIOR SYNONYMS. — (according toŠvagrovský 1971; Landau et al. 2013; and present work) Cerithium pauli Hoernes, 1875 ; Potamides monregalensis Sacco, 1888 ; Potamides Melii Sacco, 1888 ; Terebralia monregalensis Sacco, 1895 ; Clava dollfusi Hoernes, 1901 ; Clava holleri Hoernes, 1901 ; Terebralia andrzejowskii Friedberg, 1914 ; Terebralia praebidentata Seneš in Steininger et al. 1971, non Cerithium (Clava) bidentatum var. abbreviata Schaffer, 1912 [likely a synonym of Granulolabium plicatum (Bruguière, 1792) according to D. Kadolsky, pers. comm. 2018].

PALAEOENVIRONMENT. — Terebralia duboisi is believed to have inhabited mudflats and brackish palaeoenvironments ( Landau et al. 2013; Harzhauser et al. 2014).

DISTRIBUTION. — North-eastern Atlantic. Early Miocene and Middle Miocene of France ( Cossmann & Peyrot 1922; Glibert 1949). Proto-Mediterranean Sea: Burdigalian of Italy ( Sacco 1895) and Turkey ( İslamoğlu & Taner 2003); Middle Miocene (Serravallian) of Turkey ( Landau et al. 2013); Tortonian of southern Italy ( D’Amico et al. 2012). — Paratethys Sea. Early Burdigalian (Eggenburgian) of Gauderndorf ( Austria) and Vélka Čausa ( Slovak Republic) ( Steininger et al. 1971). An Ottnangian (mid-Burdigalian) record was reported by Rupp et al. (2008). Late Burdigalian (Karpatian) of Austria cooccurring with Terebralia lignitarum ( Harzhauser 2002) . Middle Miocene (Badenian) of the Central Paratethys ( Harzhauser & Piller 2007). Middle Miocene (lower Sarmatian – 12.5 Ma) of Austria ( Papp 1974); virtually absent from the Sarmatian sea thereafter, it reappears during the Bessarabian (late Middle Miocene – middle Sarmatian) roughly around 11 Ma in Ukraine, Romania, Moldova ( Kolesnikov 1935; Simionescu & Barbu 1940). — Early Indian Ocean. Early Miocene of Iran ( Landau et al. 2013).

REMARKS

Terebralia menestrieri d’Orbigny, 1844 described from the Bessarabian (Sarmatian) of Letytschiw, Oblast Chmelnyzkyj ( Ukraine) differs from T. duboisi in its smaller size and delicate sculpture. Although we regard it as a possible synonym of T. duboisi , a re-examination of the Ukrainian material would be useful for assessing the possibility that it might represent a distinct offshoot of T. duboisi .

Terebralia duboisi is among the few taxa that survive the Badenian-Sarmatian Extinction Event ( Harzhauser & Piller 2007).
