Sphaeriusidae

Need a key to the Sphaerius. Where might I find one?

Beutel and Raffaini 2003
Beutel and Raffaini 2003(1) would have cited a published key if there were one. Instead, "It is apparent that the state of sphaeriusid taxonomy is not satisfying. Therefore a thorough morphological and taxonomic treatment of the family would be highly desirable". The article does include useful information about U.S. species, though.
