Nodiscala cf. rugatina de Boury in Cossmann, 1912 (Fig. 5 View FIG A1, A2])

cf. Nodiscala rugatina – Cossmann 1912: 85, pl. 5, figs 23-25.

cf. Opalia (Nodiscala) rugatina – Zilch 1934: 228, pl. 10, fig. 72.

MATERIAL EXAMINED. — Sample F11: AMPG (IV) 2335, 2336 (two specimens).

DIMENSIONS. — Maximum height: 3 mm (incomplete).

DISTRIBUTION. — Early Miocene. Proto-Mediterranean Sea: Greece (this paper).

DESCRIPTION

Protoconch missing.Turreted, slender shell of six regularly convex teleoconch whorls; axial sculpture consists of orthocline and closelyspaced relatively prominent rounded axial costae, no varices present. Suture moderately incised;spiral sculpture composed of irregularlyspaced spiral punctuation. Aperture sub-ovate, incomplete.

REMARKS

The specimens of the present material are reminiscent of Nodiscala rugatina from the middle Miocene of Romania. The syntypes, illustrated by Cossmann (1912) and Zilch (1934), however display slightly angulated whorls and less prominent axial ribs. Therefore, we identify the distinctly older Greek species as Nodiscala cf. rugatina.

The Greek specimens are similar to Nodiscala bezanconi (de Boury, 1893) from the late Oligocene of France as illustrated in Lozouet & Maestrati (2012), but this species has more convex whorls and deeper sutures. Nodiscala bimonilifera ( Boettger, 1902), from the middle Miocene of Romania, differs in its more slender cylindrical outline and in its blunt nodes on the last whorl. The Greek specimens also show some resemblances to Opalia pertusa (Nyst, 1871) from the Miocene of the Netherlands (A.W. Janssen 1984).

Epitoniid species are known to be parasites on corals ( Kokshoorn et al. 2007).
