Temnothorax (= Myrmoxenus) kraussei is a slavemaking ant with Temnothorax recedens as slaves. As in all species of the former genus Myrmoxenus the mated young queen penetrates a nest of the host species where she throttles the host queen and is eventually accepted by the adult workers of the colony.

Most colonies of T. kraussei comprise only a small number of slavemaker workers (often less than five, rarely up to a dozen). One population on the island of Crete (Greece) has been found to be completely workerless. Colonies with a small number of kraussei workers nevertheless may try to conduct slave raids on neighboring host species colonies (cf. Temnothorax ravouxi).

The identical karyotypes of five species of the former genus Myrmoxenus together with morphological features and corresponding parasitic life history indicate monophyly of the group.
