Tellimya tenella ( Lovén, 1846 ) — Palazzi & Villari 2001 (p. 26, figs. 114–115); Oliver et al . 2016 (online resource). Montacuta tenella Lovén, 1846 — Repetto et al. 2005 (p. 315, bottom left fig.). Diagnostic characters . Sub-elliptical, inequilateral shell with longer and obliquely expanded anterior side; right valve with an oblique, knobby anterior cardinal tooth; outer surface with dense, uneven growth lines. Prodissoconch: shell type ST-2A; P-2 length exceeding 260 µm; P-1 length exceeding 90 µm (underestimated measures because of SEM image foreshortening); roundish outline; convex profile; P-1 surface unavailable; P-2 apparently well separated from P-1; P-2 with fine concentric lines, more evident towards the nepioconch; transition to the nepioconch well marked. Remarks . The shell shape stands as the distinguishing character between the present species and T. ferruginosa ( Montagu, 1808 ) . Occurrence . Box-corer sample BC72 (1 specimen); core BC21 (2). Maximum length: 3 mm . Distribution and habitat . Tellimya tenella has a NE Atlantic and Mediterranean distribution, living at shelf depths associated with burrowing urchins of the genus Brissopsis ( Palazzi & Villari 2001 ; Oliver et al. 2016 ). Fossil record. None recorded.
