Caucasotachea Explained

Caucasotachea is a genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Helicidae.^[1]

Species

The following extant species are currently classified in the genus:^{[2] [3]}

• Caucasotachea atrolabiata (Krynicki, 1833)
• Caucasotachea leucoranea (Mousson, 1863)
