Thivaiou, Danae, Harzhauser, Mathias & Koskeridou, Efterpi, 2023, Cenozoic diversity and distribution of the mangrove- and mudflat-associated gastropod genus Terebralia Swainson, 1840 (Potamididae: Caenogastropoda) in Europe, Comptes Rendus Palevol 22 (14), pp. 245-264 : 250

Terebralia subcorrugata ( d’Orbigny, 1852)

( Fig. 3D)

Cerithium subcorrugatum d’Orbigny, 1852: 80 .

Terebralia subcorrugata – Esu & Girotti 2010: 158, pl. 6, figs 4-7 (cum. syn.).

POTENTIAL SUBJECTIVE JUNIOR SYNONYMS. — Terebralia subcorrugata var. tuberculosa Grateloup, 1846 (sensu Cossmann & Peyrot, 1922); Terebralia subcorrugata var. subinterruptum d’Orbigny, 1852 (sensu Cossmann & Peyrot, 1922).

PALAEOENVIRONMENT. — Oligo- to mesohaline, very shallow tropical environments subjected to tide fluctuations, rich in organic matter and vegetation such as mangroves ( Esu & Girotti 2010).

DISTRIBUTION. — North-eastern Atlantic: Cossmann & Peyrot (1922) listed numerous localities in France (Aquitaine Basin). — Proto-Mediterranean Sea. Chattian of southern Italy ( Esu & Girotti 2010). Late Oligocene (Chattian) and Early Miocene (Aquitanian) of Greece ( Thivaiou et al. 2019; D. T. unpublished data).

REMARKS

Some specimens from the Mesohellenic Basin ( Greece) and the Esfahan-Sirjan Basin ( Iran) illustrated in Harzhauser (2004) although incomplete are most likely conspecific. A Burdigalian record from the western Taurids ( Turkey) mentioned byİslamoğlu & Taner (2003) needs verification. A specimen from the Early Miocene of Anatolia attributed to T. subcorrugata by Gürsoy (2017) is too poorly preserved to be placed with certainty in the species. A record from the Middle Miocene Badenian of Hungary, reported by Kecskemétiné-Körmendy (1962), is almost certainly a misidentification, based on an aberrant morphotype of Terebralia duboisi or T. lignitarum as presented in the mentioned work.

Specimens of Cerithium corrugatum Brongniart, 1823 have been placed in this species after re-examinations (e.g. Esu & Girotti 2010). Indeed, C. corrugatum Brongniart, 1823 from northern Italy has a similar morphology to that of T. subcorrugata but lacks a columellar fold and basal sculpture.
