DESCRIPTION

Small, white, yellow or pink, H to 6 mm, longer than high (H/L 0.89) and extended anteriorly, robust, inflated. Protoconch inflated (L 160 µm), PI smooth, 88 µm, PII with growth increments. Sculpture of prominent, rounded, regularly spaced commarginal lamellae that are often abraded. Surface of shell and lamellae with fine increments divided by lines of pits about 2.0 µm in diameter ( Fig. 37F View FIG ). Numerous fine radial folds within interspaces. Lunule long, lanceolate and impressed; umbonal area prominent. RV with large, single cardinal tooth and prominent posterior and anterior lateral teeth. LV with two cardinal teeth and two anterior and posterior lateral teeth. Ligament internal, with short, narrow, triangular resilifer. Anterior adductor scar short and rounded, barely detached from the pallial line, posterior scar ovate. Pallial line discontinuous. Shell margin outside the pallial line finely and evenly crenulate.

REMARKS

Lucina crosseana Issel, 1869 (p. 255, pl. 3, fig. 3) described from Pleistocene deposits of the Red Sea is possibly an earlier name for this species, but the type material has not been located. Zuschin & Oliver (2003: 109, pl. 25, figs 12-15) illustrate Funafutia cf. crosseana from the northern Red Sea. This is very similar to F. levukana but further work is needed to establish if it is conspecific.
