Abstract: The scarcely found Palearctic ichneumonid Ogkosoma cremieri (Romand, 1838), developing in ant nests, was recorded to occur in the territory of the city of Jihlava, Bohemian-Moravian Highlands, Czech Republic. We observed at least ten specimens of O. cremieri in the entrance of a Lasius fuliginosus (Latreille, 1798) nest, located under root shoots of white fir (Abies alba) in a light mixed forest near a tourist trail. Adults of both sexes visited the semi-cavity at the base of the trunk, in which the ants were moving around intensively, staying here for a few seconds to several minutes, and then flew away. The ant workers did not attempt to expel or attack the ichneumonids, even when they approached them to within 20–30 mm of them. Transport of L. fuliginosus larvae was not observed. We believe that increased intensity of research, its appropriate timing, expansion of the methods used and consistent cooperation of experts focused on Ichneumonidae and Formicidae will help to fill at least some gaps in the knowledge of the distribution, behaviour, and ecological relationships of this interesting species.
Key words: Ichneumonidae, Hybrizontinae, Ogkosoma cremieri, Formicidae, Lasius fuliginosus, faunistics, Czech Republic, Bohemian-Moravian Highlands
