Micrarionta borregoensis Sonorelix borregoensis, also known as the Borrego desertsnail, is a species of terrestrial snail.

[1] [2] This species was originally described, as Micrarionta borregoensis, by S. S. Berry in 1929, from a specimen collected in Palm Canyon, in what is now Anza-Borrego Desert State Park, San Diego County, California, United States.

[3][4] Berry reclassified it in the new genus Sonorelix in 1943.
