You are right! I already checked all the papers about Falsoibidion but I wonder whether this species belongs to other genus. Diagnosis of this genus (Pic, 1922) is quite ambiguous to me.
Whats more, all the species of Falsoibidion occur only in oriental region, but this species occurs all around the country, even nothern part of South korea.
In last reply, I forgot to say that it is great pleasure to participte in this forum.
