Lucinoma sp.

Fig. 8 .

Material. —MGGC.22016, a single articulated, thick-shelled specimen, 70 mm long, 67 mm high, and 39 mm thick; from the late Pliocene of Italy, Stirone seep complex.

Remarks. —The only known specimen was previously figured as Lucina sp. by Taviani and Ceregato (2009). It is very similar to the middle–late Miocene Lucinoma perusina , from which it may differ by its broader and shorter lunule and less distinct posterodorsal area. To date, this is the largest deep-water chemosymbiotic lucinid known in the Mediterranean after the Miocene. It could be a new species but we prefer at present to leave in open nomenclature.
