Comments. I have examined the type species of all mentioned genera and found them congeneric as they share the following features ( Figs. 10–11 ): metope wide, widest above clypeus, with weak incomplete median keel and four joined sublateral keels forming a doublehorseshoe shape; coryphe transverse, twice as wide as long, anterior margin weakly convex; fore wings wide, with long clavus reaching wing apex, without hypocostal plate; hind wings well developed; hind tibia with two lateral spines distally.
