The Banbury Springs lanx (Idaholanx fresti), or Banbury Springs limpet, is a rare species of freshwater snail, an aquatic gastropod mollusk in the family Lymnaeidae. First discovered in 1988, the species was formally described and named in 2017.[1]
Distribution
This freshwater limpet is endemic to the US State of Idaho, where it is known from a 10-kilometer stretch of the Snake River. It is found in four complexes of springs along the Snake River in south-central Idaho: Thousand Springs, Box Canyon Springs, Banbury Springs, and Briggs Springs.[2]
Description
This snail is cinnamon red in color. The shell is conical in shape. It is up to 7.1 millimeters long by 6 wide and up to 4.3 millimeters tall.
This snail is similar in its morphology to species in the genus Lanx, but genetic analysis reveals that it is genetically more similar to the genus Fisherola.[2]
Conservation
In 1992 it was federally listed as an endangered species of the United States.[3]
