One new species of the genus Harmozica, similar to the widespread in the Caucasus Harmozica (Diplobursa) pisiformis, is described from Southern Armenia (Syunik Region). The shell of Harmozica zangezurica sp. nov. different from H. pisiformis by slightly higher shape and more reflexed columellar margin of the aperture, which covers at least half of the narrow umbilicus. The clear anatomical difference of the new species from H. pisiformis and other species of the genus Harmozica is very large vaginal appendages, the length of which is approximately equal to the total length of the penis and epiphallus. A key to the Caucasian species of Harmozica is provided.
