DESCRIPTION
Turreted solid shell with flat whorls, with deep sutures. Sculpture consisting of four distinct spiral cords spaced by deep grooves of equal width. A fifth inconspicuous spiral thread appears above the adapical suture. Wide-spaced prominent axial ribs may form small varices; a well-developed varix is present on the last whorl; base of the last whorl bearing four granulated spiral threads. Aperture ovate with prominent columellar fold; siphonal canal thin and short.
REMARKS
This species is reported here for the first time from Greece. The two specimens of T. subcorrugata found in Felli show the features of both juveniles and adult specimens, although the protoconch is missing. Esu & Girotti (2010) recorded this species in the Oligocene of southern Italy where few specimens were available, illustrating low morphological variation. The Felli material is insufficient to deduce any variability, but as agree in shell characters with the Italian specimens, differingin having weaker and less spiny axial ribs. Terebralia cf. subcorrugata from the Oligocene of Iran (Harzhauser 2004) has more convex whorls but displays the same axial sculpture. It is easily distinguished from Granulolabium plicatum by the more prominent spiral sculpture.The specimens from Felli are morphologically almost identical to the French representatives from the Early Miocene of the Aquitaine Basin housed at the historical Cossmann collection of the Muséum national d’Histoire naturelle (Paris).
Recent representatives of Terebralia are limited to the Indo- Pacific Ocean, and are associated with mangrove environments (Plaziat 1995). In the Oligocene of Iran, T. cf. subcorrugata has been found with Granulolabium plicatum, Vitta cf. picta and Cerithiidae (Harzhauser 2004).
