Species of Anagrus Haliday, 1833 (Hymenoptera, Chalcidoidea, Mymaridae) in Navarra (Spain).- Six species of Anagrus, collected with a Malaise trap and a sweep net, were captured during the study of the entomofauna of 60 corn fields in the province of Navarra. These species are Anagrus atomus (Linnaeus, 1767), A. similis Soyka, 1955, A. incarnatus Haliday, 1833, A. obscurus F6rster sensu Soyka, 1955, A. subfuscus F6rster, 1847 and A. optabilis (Perkins, 1905). AII of these are new for the Iberian peninsula. Information about their hosts, and their role in biological control are given.

Key words: Hymenoptera, Mymaridae, Anagrus, Zea mays, Navarra, Spain.
