Epioblasma biemarginata (I. Lea, 1857)

Angled riffleshell

Taxonomy & Nomenclature

Synonym/s: Dysnomia biemarginata I. Lea, 1857

Conservation Status

Extinct

Last record: 1970

IUCN RedList status: Extinct

The Angled riffleshell was last seen in 1970 (Williams et. al. 2008).

Distribution

Alabama/Kentucky/Tennessee, USA

It is known to have occurred historically in three states: Alabama, Kentucky and Tennessee. Bogan (2000) lists Illinois as another state in which this species occurred. However, an extensive review of the literature (NatureServe, 2011) does not mention Illinois as a confirmed location of this species, nor does it even mention Illinois in the entire species account.
