The surprise
is the naming of the
protoconch. Juvenile Nerita albicilla were named
Nerita fasciata;
understandable because they do differ from the adult,
but naming a
protoconch. What a great story and the illustrations
on youir web
page are exquisite. One look and you can easily see
how the
mistake came about (http://www.jaxshells.org/martinia.htm).
Thanks for sharing,

Dear Carole,
This is an important topic! Thanks for bringing it up
in this
forum.
Tom has already set the record straight on much of
this.
What may be a surprise to some Conch-L'ers is that
WoRMS
<
http://www.marinespecies.org/aphia.php?p=taxdetails&id=476533
>, based on "personal communication" from
Alan Beu (2010),
synonymized the amphi-Atlantic Monoplex
martinianus
(d'Orbigny,
1841) with M. pilearis (Linnaeus, 1758) [type
locality.
Despite
opinions to the contrary (e.g., Abbott, 1974), for
decades Beu
steadfastly separated the two until he reached the
point in his
extensive, nay, global, museum work that he wrote
"the distinction
between specimens resembling M. pilearis and
M.
martinianus
is not clear-cut and not supportable" (Beu, 2010:
170)
While typical specimens of M. p., e.g., from
the
Philippines and
M. m., say, from Florida have always appeared
distinct in
my
(proportionately meager) experience, I'll yield to
the expert on
their
conchological affinity - but how about affording our
Atlantic
taxon
subspecies status? Lee (2009: 83) gave distinguishing
characters.
Beu and many others, e.g., Lee (2009: 82-83), have
unequivocally
separated M. p. from M. aquatilis so
"pileare was changed to
aquatile"
is certainly not a mainstream opinion - and one
I find
indefensible. Likewise M. macrodon is
not
synonymous with
M. pilearis; these WoRMS citations are based on
historic
misidentifications. Although confused by many authors
over the
years,
both species are recorded from NE Florida
<
http://jaxshells.org/marine.htm> and Peanut
Island
<
http://jaxshells.org/peanut.htm>, to which
inventory
you've made
prodigious contributions.

Hi conch-L Seems with
all the
facebook and other sites, we have been very quiet.
Hoping there
is still
someone tuned in. Went to access Cymatium pileare,
it is listed
in WoRMS
as Monoplex macrodon (Valenciennes, 1832) with a
reference by
Gary
Rosenberg, but I cannot find any other information
on this. Does
anyone
have the paper. It is probably pretty recent as last
I had any
information, pileare was
changed to
aquatile.
Can anyone shed any light on this.
Thank you,
Carole M
