In the context I had in mind five monotypic genera, five type species, the
4th being Mercierellopsis prietoi Rioja, 1945, synonymous with
Ficopomatus miamiensis. This was rather pedantic/obscure of me.

With the hindsight footnote that a good deal of that widespreadedness was
Indo-Pacific F. uschakovi in the northern parts. Also, let us remember that
the "Australian origin" comment was only as a possible source of the
population that turned up in Fauvel's study area. I interpret Allen as
suggesting that Australia was a mere staging-post and that the true origin of
the species was unknown. The absolute alarm-bell sentence in Allen is "In
many of the [southern Australian] localities where it is now abundant it was
previously unknown." It is a great pity that Allen did not document this in
any more detail.
