Dear all,
I am working on the description of a new Costoanachis dove shell species,
which I want to name venusta. I need some help; is the name venusta
already
preoccupied by another species of Costoanachis? It is vital that I know
this. I don't
want to put a name that is already in use on a new species. Anyone out
there who can
help?

Thanks,
James
