Genaxinus eumyarius (M Sars, 1870 ) — Oliver et al . 2016 (online resource). Diagnostic characters . High subquadrangular shell; two strong, elevated myophores; anterior myophore wide and drop-shaped; posterior myophore narrow and long. Prodissoconch: shell type ST-2D; length about 120 µm; roundish D-shaped outline; convex profile; surface with a net-like sculpture of wrinkles, more raised on the cicatrix area; P-2 replaced by shell lip; transition to the nepioconch well marked. Remarks . We follow Oliver & Levin (2006) in assigning this species to Genaxinus Iredale, 1930 , rather than Axinulus Verrill & Bush, 1898 , which seems to have normal (i.e. not raised) adductor scars. Occurrence . Box-corer samples BC04 (1 specimen), BC66 (1), BC72 (7); core BC72 (2). Maximum height: 2 mm . Distribution and habitat . The species is reported to be widespread in all the Atlantic and the Mediterranean, from 50 to over 2600 m , lacking the symbionts co-occurring with many lucinid species ( Payne & Allen 1991 ; Buhl-Mortensen & Høisaeter 1993 ; Oliver et al. 2002 , 2010) Fossil record. Pliocene of Sicily ( Monterosato 1872 ).
