REMARKS. K. Tsuneki (1963: 9) in the description of a new subspecies Lestiphorus bilunulatus yamatonis indicates: “subspecies differs from nominate race in the sculpture of the area cordata on the propodeum and somewhat in coloration”. The study of material (see above) showed a great variability of the sculpture of the metapostnotum – from short ribs,

occupying about half of the metapostnotum (as in “nominate race” in the understanding of

Tsuneki), to almost reaching its apex, at the same time, there is no geographical pattern.

Thus, due to the inability to reliably identify the subspecies Lestiphorus bilunulatus yamatonis

Tsuneki, 1963 as well as the absence of geographical boundaries, we are considering it a junior synonym of Lestiphorus bilunulatus A. Costa, 1867 .
