The wing is very similar in size and venation pattern to the wing of the holotype Emplastus hypolithus USNM 61411, from was described from the Eocene locality Bembridge, Great Britain (Fig. 3c). Small differences are observed in the wing sizes, in the relative length of the 2M + Cu and 4RS sections. Taking into account some differences in venation and due to the time interval separating these records, it is possible to describe a new species.

The peculiarity of the described venation pattern is a combination of the characters that are each present in the wings of different extant dolichoderine genera, but do not occur together in any of them: the size of the wing is relatively small, the m-cu length is slightly greater than that of 1M, and the 4RS section is well-expressed. As a result, the assignment of the wing to the orthotaxon cannot yet be justified.


This taxon was described from Velikaya Kema, Primorye, Russia (Chattian, Oligocene).
