Caucasotachea is a genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Helicidae. ^[2]

Species

The following extant species are currently classified in the genus: ^{[3] [4]}

• Caucasotachea atrolabiata (Krynicki, 1833)
• Caucasotachea leucoranea (Mousson, 1863)
• Caucasotachea vindobonensis (C. Pfeiffer, 1828)

Several fossil taxa are placed to Caucasotachea:
