Eoformica expectans

Two fossil species of Gesomyrmex were described from the Oligocene of Germany based on incomplete compressions (Théobald, 1937) but were excluded from this genus by Dlussky et al. (2009): Gesomyrmex expectans was transferred to Eoformica and Gesomyrmex miegi was treated as incertae sedis in Formicidae (Aria et al., 2023).
