Abstract
Three Palaearctic species of Macromyrme Lelej 1984 from the tribe Mutillini are reviewed. A new species, M. leleji Soli-man, sp. nov. from South Sinai (Egypt) is described. Mutillidae or "velvet ants" represent a large family of solitary wasps withina large hymenopteran group known as Aculeata, in which the female's ovipositor serves to deliver venom, but is not used in egg laying. Mutillidae exhibit strong sexual dimorphism, the males are fully winged (rarely brachypterous or apterous) and possessa normal apo-critan mesosoma, while the females are entirely apterous and most of them exhibit complete fusion of the meso-somal sclerites. Mutillids are well known as ectoparasitoids of digger wasps, bees and some Vespoidea (Brothers et al. 2000), withsome exceptions: two mutillid species of the genus Chrestomutilla have been reported to parasitize tsetse flies (Glossina, Diptera) in Africa (Brothers 1971). Two species of Macromyrme Lelej occur in the Palaearctic region and ten species in the Afrotropical region (Lelej 2007). Bischoff (1920) included these species in his new genus Pycnotilla (junior synonym of Ronisia Costa 1858). The Palaearctic species are Macromyrme binotata (Radoszkowski) and M. sinuata (Olivier). In addition, a new species M. leleji sp. nov. (Egypt) which considered the first record of subfamily Mutillinae in Sinai Peninsula (Egypt) was detected during the present study.
