Sonorella is a genus of large land snails consisting of over 80 species, with new ones continuing to be described.

[7] Like other species of the genus, the shell of S. neglecta is a little flatter than spherical, pale brown in colour with a chestnut peripheral band.

[9] Walter Miller later visited the type locality and found the first living specimens, describing their genital anatomy in his doctoral thesis.

NatureServe has classified S. neglecta as "critically imperiled" on account of the few known localities and lack of recent records.

[11] This prompted a petition in 2007 to classify S. neglecta, along with hundreds of other species, as "endangered or threatened with critical habitat", which was turned down by the United States Fish and Wildlife Service in 2009.
