Lasius vulgaris

Identification
Wing measurements of the majority of the described fossil Lasius species and two Leucotaphus species differ from the described species. Wing measurements in the Oligocene Lasius epicentrus are similar; however, the wing pattern is insufficiently detailed for analysis. Of particular interest is the comparison with other Miocene species of a suitable size class: Lasius anthracinus and L. occultatus have a higher mcu cell, in Lasius ophthalmicus] cu-a is located much farther from the mcu cell, [[Lasius validus and Lasius chambonensis have a relatively shorter 3r cell. Chinese Lasius truncatus is without wings; therefore, comparison cannot be performed. Leucotaphus donisthorpei differs in its relatively small mcu cell.

Judging by the proportions of the wings, the smaller wings belong to the males, and the larger ones belong to the female. Since other features of venation are very similar, I consider it possible to combine the three imprints into one species. The absolute sizes of the wings were calculated from the reconstructions performed on the basis of the analysis of the shape of the wings of extant Lasius.
