New species of chalcidoid wasps of Eurytomidae and Ormyridae families (Hymenoptera, Chalcidoidea) from Saudi Arabia [Russian]

摘要

Three new species of chalcidoid wasps of Eurytomidae (Nikanoria arabica Zerova et Dawah sp. n., N. suaedae Zerova et Dawah sp. n.) and Ormyridae (Ormyrus desertus Zerova et Dawah sp. n.) families are desribed from Saudi Arabia. Nikanoria arabica Zerova et Dawah sp. n. is similar to N. koelpiniae Zerova but differs from it by longer cheeks, longer flagellant segments in females, longer pubescens in males, and by the sculpture of propodeum with large cells in the center. The species N. suaedae Zerova et Dawah sp. n. resembles N. verticalis Zerova by color, but differs by longer seventh abdominal tergit in female. Ormyrus desertus Zerova et Dawah sp. n. differs from all known species by very long seventh tergite in females and enlarged stigmal knob in males. The species described were reared from Cecidomyiid galls on Suaeda monoica (Chenopodiaceae) in a desert region of Saudi Arabia. The types of the new species are deposited in the collection of the Institute of Zoology (Kiev, Ukraine).
