To add to the confusion it is also a primary junior homonym of Rotalipora cushmani var. evoluta Sigal, 1948 and should be renamed. (see please previous comment)

Citation: Thalmanninella evoluta (Petrizzo & Huber, 2006)?

The 'original unavailable name' is Rotalipora praebalernaensis forma evoluta Sigal, 1969 it is not available under ICZN rules.

See ICZN art. 45.5. and following

If Petrizzo and Huber (2006) were the first to use Rotalipora evoluta (p. 181), they are deemed to be the authors with the date 2006.

That certainly looks correct, I will have to add that to the list of taxonomic issues for Brian Huber to consider .

thanks Jeremy
