New braconids of the genus Microchelonus with yellow abdominal spots in the female, similar to M. fenestratus (Nees) (Hymenoptera: Braconidae)

Abstract. Four new species of Microchelonus (M. chrysomacula, M. sochiensis, M. tedzhenicus, M. vitalii spp. n.) and the male of M. xanthozona (Alaxeev, 1971) are described and illustrated. All of them have yellow basal abdominal spots in females and usually also in males; in this and some other characters they are similar to M. fenestratus (Nees, 1816). Two of the four new species and the male of M. xanthozona are described from Turkmenistan, M. sochiensis from the Russian Black Sea coast, and M. chrysomacula from Mongolia.
