The Jackson lake springsnail, scientific name Pyrgulopsis robusta, is a species of very small or minute freshwater snail with an operculum, an aquatic gastropod mollusk in the family Hydrobiidae. This species is endemic to the United States. The shell is 4.6 to 7.5 millimetres (0.18 to 0.30 in) high and 1.48 to 2.10 millimetres (0.058 to 0.083 in) wide, which is large for this genus. It has 4.5 to 6.25 whorls, and is clear-white with a tan periostracum.[2]

Taxonomy

In 2004, two species (P. idahoensis and P. hendersoni) were reclassified as P. robusta based on genetic analysis. The species description was amended to capture a broader range in morphology.[2]
