Zusammenfassung

Data on host species and the distribution of the endoparasitic fungus Myrmicinosporidium durum increased continuously in recent decades. Here, we add the ant Cardiocondyla elegans as new host species. Colonies of the monogynous species were found infested in the region of Languedoc-Roussillon (South France). Samples from the nest indicate high infection rates. All castes and sexes were infected by the spores. Variations of infection rates between sampling methods and species are discussed.
