Remarks.

This species was included in the subgenus Fungivenator van Achterberg & Shaw, 2008 of the genus Colastes Haliday ( van Achterberg and Shaw 2008) . However the material of our study from China, Korea, and the Russian Far East distinctly shows that the members of this species have a distinct and deep round pronope, which together with some other characters (complete notauli, radial vein (r) of the fore wing arising almost from middle of pterostigma) demonstrate that it belongs to Xenarcha (subgenus Xenarcha).
