Diplazon tibiatorius (Thunberg, 1824)

All the specimens of this species recorded by Momoi from Mongolia either belong to D. annulatus, D. multicolor or D. varicoxa (Thomson, 1890) . As the publication by Momoi is the only record of the species from Mongolia, D. tibiatorius has to be removed from the Mongolian list until further evidence supports its presence.
