Hi James,
I can't help you much with syonymy in this group, but here are a few more
names:
Erato (Eratoena) nana (Sowerby), from Japan
Erato (Proterato) bimaculata (Tate)
Erato (Proterato) angistoma (Sowerby)
Erato (Sulcerato) denticulata (Pritchard & Gatliff)
Erato (Sulcerato) lachryma (Sowerby)
(the last 4 all from Australia)
Regards,
Paul M.
