Titanopoma A. J. Wagner, 1897, a subgenus of Cochlostoma Jan, 1830, is revised on the basis of the material in the Hungarian Natural History Museum (Budapest), the Natural History Museum of the Humboldt University (Berlin) and the Zoological Institute and Museum of the Polish Academy of Sciences (Warsaw). Two species and five subspecies are described as new to science. Shells and opercula are illustrated. Because of its relevance for species recognition in this group, the structure of the opercula is described in more detail than usual. Locality records and some new zoogeographical data are given and mapped.
