Anisodonta lutea Dall et al., 1938: p. 124 , pl. 34, figs. 7–10. Anisodonta lutea Dall et al., 1938 — Kay, 1979: p. 552, fig. 170 M; Raines, 2002: p. 35, fig. 43; Tröndlé & Boutet, 2009: p. 8. Basterotia lutea ( Dall et al., 1938) — Severns, 2011: p. 472, pl. 216, fig. 2.

Material examined. Over one hundred single valves (3 to 7 mm) from EI and SyG (BK), plus specimens from the Hawaiian Islands ( MHU).

Diagnosis. Shell small (up to 7 mm in length), subquadrate and inflated. Dorsal and ventral margins nearly parallel. Posterior end obliquely rounded with a low ridge from the umbo to the ventral margin; anterior end well rounded. Sculpture consisting of only commarginal growth lines. Hinge consistent with genus having a hook-like tooth below the beak of the LV. Color creamy white.

Remarks. The specimens from EI and SyG conform well to the Hawaiian material. Basterotia lutea was originally placed within the genus Anisodonta Deshayes, 1858 , but this genus is limited to European fossils only ( Huber 2010: 663).

Hawaiian specimens were not described or recorded above 6 mm.

Habitat. Commonly found at many locations around EI and SyG, in sand and rubble, from 20–50 m.

Distribution. Basterotia lutea is currently known from the Hawaiian Islands, Society Islands, Tuamotu Archipelago, Easter and Salas y Gómez Islands— E4.
