This recently described species was discovered from a vernal pool in Seth Forest, near Easton, Talbot Co., MD. in the 1970s. It was described in an unpublished PhD thesis by J. Hellman, but the names given would be manuscript names only, without a publication. The species was feared extinct after habitat destruction at the type locality, but it has since been rediscovered at a small number of similar pools, all in the Delmarva Peninsula.
