摘要：

The evolutionary relationship between socially parasitic ants and their hosts is still an unsolved problem. We have compared a 1.2 kb sequence of the 18 S ribosomal RNA genes of the parasitic ants Doronomyrmex kutteri, Harpagoxenus sublaevis and Chalepoxenus muellerianus to the sequence of the host species Leptothorax acervorum and L. recedens (all subfamily Myrmicinae, tribe Leptothoracini) and to an out-group ant Camponotus ligniperda (Formicinae). We found that parasitic species and the host species and also Camponotus ligniperda differ at less than 1% of the base positions of the 1.2 kb segment of the 18 S rRNA gene. The sequences showed 80.3% identity to the 18 S ribosomal RNA genes of the beetle Tenebrio molitor and only 66.5% to that of the dipteran Drosophila melanogaster.
