Beecher (1893) elevates this taxon from a variety (or subspecies) of Terebratella occidentalis, to species status. On p. 382 (footnote) for T. obsoleta it is remarked "Originally described as Terebratella occidentalis var. obsoleta, by Dall but now considered by him a distinct species". Thus, this variety and its citation "Dall, 1891" rather than "Beecher, 1893" is the correct taxonomic citation, as recognized by BrachNet (Brachiopod Database).
