Distribution (fig. 10). Mongolia (Govi-Altai Province, Bayankhongor Province, Ömnögovi Province, Dornogovi Province), and China (Inner Mongolia).

Remarks. This species is similar to Rh. solskyi but easily distinguished by wider apex of the aedeagus, distinctly transverse rugose elytral interstriae and body usually with golden sheen. There are collections of both species from the same localities at the same time from Southern Mongolia. Rh. lukjanovitschi and Rh. solskyi species probably co-occur in some parts of their distribution, as Rh. solskyi and Rh. gebleri .
