Mussel of the Month

The May 2016 Mussel of the Month is Iheringella semisulcata. Iheringella is a genus of two poorly known species in South America.

Iheringella semisulcata
BMNH 1907.10.28.128. Eastern Peru; Bartlett! (type)

Google Iheringella semisulcata and you will receive links to this web site, as well as to other online databases, that confirm that the species exists — or, more accurately, that confirm that the name exists and has been used for a species of freshwater mussel. There are also some links to some key works like Simpson (1900, 1914), Haas (1969), and Graf & Cummings (2007).

That Google search only turned up 5 pages of links, and we are responsible for almost the entirety of the first page! Conspicuously absent from that list is a link to Pereira et al. (2014). That paper is a recent comprehensive checklist of the freshwater mussels of South America. The word 'Iheringella' does not occur in their article. Did they omit it? Or has it been synonymized? The genus is so poorly known and so infrequently mentioned, it is easy to see how it could slip through the cracks. Until we know for sure, we will keep it on our list.
