Summary.

By combining different methods we evaluate whether the ant Tetramorium rhenanum is specifically separated from T. moravicum or whether it is a conspecific microgyne form. High-precision morphometry shows a clear difference in queen size. Sequence comparison of 1031 bp of COI reveals that T. rhenanum falls into a clade with T. moravicum, which is significantly separated from T. forte and T. chefketi. T. rhenanum shares at least two haplotypes with T. moravicum and is considered as a junior synonym. Sexual behaviour and colony foundation experiments corroborate conspecificity. The queen dimorphism is discussed in the context of social parameters such as queen number and reproductive strategy.
