New eyeless snail discovered in Greece, named after the god Hermes

New snail species unearthed in Greece

According to НВ — Техно: On July 18, 2026, researchers from the National and Kapodistrian University of Athens announced the discovery of a new genus and species of subterranean freshwater snail, designated Cyllena hermes. The snail was found in a single karst spring in the Peloponnese region of southern Greece, at an elevation of about 610 meters near the base of Mount Kyllini in Corinthia. It is unpigmented, eyeless, and adapted to life underground.

Ecological importance and conservation status

Cyllena hermes is known only from this one location, within the described karst spring. Groundwater from the spring feeds a stream that flows into Lake Stymphalia. Based on the International Union for Conservation of Nature (IUCN) Red List criteria, the species is classified as vulnerable, highlighting the need for its protection.

The genus name Cyllena honors the nymph Cyllene (Κυλλήνη), while the species name hermes pays tribute to the god Hermes (Ἑρμῆς), who, according to Greek myth, was born in a cave on Mount Kyllini. This find not only enriches our understanding of Greece's biodiversity but also underscores the importance of preserving unique ecosystems that may be threatened by human activity.

It is worth noting that the discovery of a new species highlights the significance of karst systems in ecological balance and the need for their study and conservation.

Scientists hope that further research will clarify the ecological role of Cyllena hermes and its impact on the environment. This discovery may also spur conservation efforts for natural habitats, which is crucial for maintaining regional biodiversity and preventing the extinction of rare species. Given the vulnerability of this new species, its protection will become a key task for environmental organizations and local authorities.
