Abstract

Two new species of Idiomacromerus Crawford (Hymenoptera: Torymidae), Idiomacromerus luteus Nieves-Aldrey & Askew and Idiomacromerus mesoplanus Askew & Nieves-Aldrey are described from Spain. The two new species were reared from stem galls in the opium poppy, Papaver somniferum L., induced by the cynipid Iraella luteipes (Kieffer) (Hymenoptera: Cynipidae). The last instar of I. luteus also is described, and the generic placement and taxonomic affinities of the two species are discussed. Data also are given on the biology of the new species, including illustrations of the host plant and galls. I. luteus and I. mesoplanus are part of a community of undescribed parasitic chalcid wasps associated with the opium poppy stem gall. The remaining species will be described elsewhere.
