description
Sympycnus urgaicus: HOLOTYPE ♂, labelled: Russia: “ Sajangebirge, Arschan, 2. VII. 1965, Negrobov ” / Sympycnus urgaicus Negrobov (ZIN).
discussion
Remarks. Our examination of additional material has revealed intra-specific variation in leg coloration, and mid tibia and hind tarsus (Fig. 3) 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). 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.
