Remarks. Our examination of additional material has revealed intra-specific variation in leg coloration, and mid tibia and hind tarsus ( Fig. 3 View FIGURES 1 – 6 ) setation in this species. A re-examination of macerated hypopygia of the holotypes of Sympycnus changaicus , S. convergens and S. urgaicus has revealed that the hypopygial appendages are identical in all the specimens studied ( Figs 5–6 View FIGURES 1 – 6 ). The fore tarsus illustrated in Negrobov (1973, fig. 32) is actually Rhaphium sp. rather than S. convergens , being erroneously included in the paper. We consider all three of these species to be synonyms.

Distribution. Palaearctic: Mongolia. New for Transbaikalia Region, Altai, Buryatia and Yakutia Republics of Russia.
