Taxonomic Comments
The subgenus Hinkleyia is elevated to genus level (Correa et al. 2010); this arrangement is accepted by FMCS (2021) and MolluscaBase (2022). See Vinarski (2013) for a discussion on the generic classification of the family Lymnaeidae.

Hemphill (1890), who named and described this species, placed it in the genus "Limnaea" (= Lymnaea). Baker (1911) assigned the species to the genus Galba. Man (e.g., Taylor et al., 1963, Russell, 1971) have arranged it as a species of Stagnicola. Taylor et al. (1963) demonstrated that, within Stagnicola, the species belongs to the subgenus Hinkleyia. Clarke (1991) argued that the species should be assigned to the genus Bakerilymnaea; he called this species the "Fish Springs lymnaeid". Nevada was incorrectly cited in original description of type locality; it should have read, "Fish Spring [Juab County], Utah" (see Oliver and Bosworth, 1999), so the citation in Burch (1989) is incorrect. Jackiewicz (1998), states that there are several problems concerning the nomenclature of the family Lymnaeidae, and that there is probably no other snail group in such taxonomical disarray. Stagnicola has been used as a synonym for Lymnaea by various authors, and as a subgenus of Lymnaea by others (Ponder and Waterhouse, 1997; Vinarski, 2003). Hovingh (1993) lists this species as Lymnaea (Stagnicola) pilsbryi. Dillon (2009) suggests that Lymnaea pilsbryi is a synonym of Lymnaea humilis, but this is neither supported or denied in other literature.

Rank Reasons
This species is extinct and only known from the Utah type locality. Nevada was incorrectly cited in original description of type locality; it should have read, "Fish Spring [Juab County], Utah" (see Oliver and Bosworth, 1999), so the citation in Burch (1989) is incorrect. It is likely extinct with the last confirmed occurrence in 1868.
Range Extent Comments
This species is extinct and only known from the Utah type locality. Nevada was incorrectly cited in original description of type locality; it should have read, "Fish Spring [Juab County], Utah" (see Oliver and Bosworth, 1999), so the citation in Burch (1989) is incorrect.
Occurrences Comments
Russell (1971) found shells in Fish Springs in Juab Co., Utah, only but he supposedly reported that some of the shells appeared to have been relatively fresh. Live individuals or fresh shells have not been found since then including a targeted survey by Clarke (1991) in 1990; therefore the last live collected individuals were in 1868.
