Emplastus haueri

Another species based on an impression fossil of a queen, the identity of this taxon remains obscure. Dalla Torre (1893) transferred it to Iridomyrmex, a treatment followed by Shattuck (1992a). Mayr’s (1867b) figure of the type queen reveals little detail other than wing venation. While the general pattern is dolichoderine-like it differs from extant species of Iridomyrmex in having the Rs vein join M at 1m-cu, rather than basal to this cross vein, resulting in the cell enclosed by Rs, M and 2rs-m having three sides rather than four. A three-sided cell similar to Mayr’s (1869) figure for this species is present in some Dolichoderus (especially species formerly placed in Hypoclinea), a condition not seen in Iridomyrmex. Because of this it would seem that this species would be better placed in Dolichoderus rather than Iridomyrmex.

Distribution
This taxon was described from Yugoslavia (Miocene).
