New materials of Tandonia totevi (Wiktor, 1975) from Bulgaria have enabled the authors to prepare a detailed redescription and to distinguish the species from those from southern Greece which have been confused with T. totevi for almost 30 years. From the southern Greek Islands, the Peloponnese and the island of Euboea at least three more species need to be described and discriminated from T. totevi. The spermatophores of T. totevi from Bulgaria are described here for the first time, as is an intra-integumental glandular secreting organ of unknown function. The first description of spermatozoa of T. totevi is included. The first photographs of living specimens and the first observations on the behaviour and ecology are provided.
