Mussel of the Month

The September 2011 Mussel of the Month is Unionetta fabagina. Unionetta is a genus of only two species in the Mekong River of southeastern Asia.

Unionetta fabagina
MNHN. Mekong River, Sombor, Cambodia (type).

Unionetta is one of those genera about which we know almost nothing. A Google Scholar search reveals that the only publication in the last 10 years that cites this mussel is our own global species checklist (Graf & Cummings, 2007). Since things are busy with the beginning of the Fall semester, we will take the opportunity to keep this month's entry short.
