Andrew,

In Henning & Hemmen (1993) the authors treat Lotoria as a subgenus of
Cymatium.  On page 55 they say "The subgenus Lotoria differs from Cymatium
s.str. by the rounded, not flattened and expanded varices and the form of
the anterior channel."

There may be more information in the paper by Emerson & Old (1963) where
they describe Lotoria as a new subgenus, but I do not have this paper.

Warm regards,
