Known from several Caves in Crete, a cave in the central mainland of Greece, a cave in Evvoia island (synonymized with T. euboensis), and the Aegean island of Tinos. There are possible synonymies between T. lindbergi, T. cavernicola, and T. intermedius. The taxonomy of this species-group (including T. euboensis) needs further investigation (Schmalfuss et al. 2004).
