Lyonsiella cf. magnifica Dall, 1913 Fig. 12

Examined material.

1 live specimen EA345 (2.5557°N, 79.0476°W) at 668 m (INV MOL9804).

New location.

Off Nariño, Colombian Pacific.

Distribution.

Mexico to Panama ( Coan and Valentich-Scott 2012).

Remarks.

Colombian material resembles the type material of Lyonsiella magnifica. However, our specimens have more prominent umbones, a more truncate anterior end, and a more obliquely truncate posterior end when compared to the type material. Many additional specimens would be necessary to determine if our single specimen falls within the range of intraspecific variation for Lyonsiella magnifica or it represents a new species.
