Michael,
I did not know about the designation of Theodoxus fluviatilis, thank you!
I'll have to note that in the write up of that species in the book. The
book is coming along. I have pretty much all the valid species I could find
identified, described, and imaged. Now I have a bit more to do on the
anatomy (drawings and descriptions) and some S.E.M. photographic work.
Plus, I have to have a bunch of folks review the MS.
My entry in the book on Pictonerita is:
"Pictonerita Iredale, 1936 – unused, proposed as a genus with a single
species, Neritina oualaniensis Lesson, 1831 (now Clithon oualaniensis),
based on radular differences noted by Baker (1923). Baker, however, did not
consider these differences sufficient to warrant a subgenus or even a
section! Holthuis (1995:61) reports that, “The anatomy of N. oualaniensis
indicates a very close relationship with Clithon corona Monfort, 1810, the
type genus of Clithon.”"
Hope this helps answer the question. I have attached my latest species list
which should help you.
Tom

Subject: Neritidae questions to Tom Eichhorst
Hi Tom,
currently working on the Neritidae part of my collection, I took your
preliminary genus list of the Neritidae from an earlier posting of yours as
a base for the taxonomic array. In this list you don't mention the
(sub)genus Pictoneritina Iredale 1936, now presumably a subgenus of
Theodoxus. What happened to that taxon? Does it only include Theodoxus
(Pictoneritina) oualaniensis (Lesson, 1831)?
You also mentioned a book on Neritidae you were working on. How far has the
project grown in the meantime?
BTW, did you know that Theodoxus (Theodoxus) fluviatilis (Linnaeus 1758) was
"Mollusc of the year" in Germany in 2004? Take a look at
http://www.mollusken-nrw.de/weichtier_des_jahres/weichtier2004.htm (in
German).
Greetings from Germany
Michael
