Genus Elliptiolucina Cosel and Bouchet, 2008

Type species: Elliptiolucina magnifica Cosel and Bouchet, 2008 ; Recent , central Philippines .

Remarks. —This genus is characterized by having a subquadrate-ovate and weakly inflated shell, an edentulous hinge except for small cardinal and anterior lateral teeth in E. williamsae Glover and Taylor, 2016 , and a short anterior adductor scar. Other edentulous lucinids with a weakly inflated, elongate shell include Nipponothracia Kanie and Sakai, 1997 , Elongatolucina Gill and Little, 2013 , and Amanocina Kiel, 2013 . According to Okutani (2011), Elliptiolucina can be separated from Nipponothracia by its smaller and thicker shell and possession of a characteristic dorsal concavity in the posterior adductor muscle scar. Elongatolucina has an elongate shell with straight ventral margin, which is not seen in Elliptiolucina (see Kiel 2013). Amanocina can be easily distinguished from the other genera as it lacks a subumbonal triangular excavation and has a longer adductor muscle scar detached at a narrower angle from the pallial line (Kiel 2013).
