†Camponotus tokunagai Naora, 1933

The taxonomic placement of C. tokunagai is highly doubtful. The author’s drawing of the wing not only does not correspond to Camponotus venation but is not comparable to any type of wing venation in ants. Additional study will be required to determine the correct treatment of this taxon (Perfilieva, 2022).

Distribution

This taxon was described from Fushun amber, Liaoning, China (Ypresian, Early Eocene).
