Remarks. The ♀ mesosoma of Gonatopus festivus Olmi can vary in colour, from totally testaceous to partly black or brown. If the colour is partly black or brown, ♀♀ of G. festivus can be confused with G. harteni Olmi. In this case, ♀♀ of these two species are indistinguishable. However, the two species are distinct, because their ♂♂ show strong differences.
