In conclusion, 2 valid species are maintained: Cylindroiulus horvathi (Verhoeff, 1897), and C. abaligetanus Verhoeff, 1901. One new species is added to the group, Cylindroiulus cambio sp. n., which is described from Rostov-on-Don, Russia. Cylindroiulus vitosae Strasser, 1962 and C. ponticus Golovatch, 1978 are synonymized with C. horvathi.
