The first occurrence of Neotrichoporoides nyemitawus (Rohwer, 1921) (Hymenoptera: Eulophidae) in the West Palaearctic with a key to the known species from Iran.

Through a survey that was conducted from 2020 to 2021, specimens were collected from wheat fields (Triticum aestivum L.) in West Azarbaijan province in the northwest of Iran using a sweep net. These are Neotrichoporoides nyemitawus (Rohwer, 1921), a new report for Iranian fauna and the West Palaearctic subregion. Illustrations of N. nyemitawus are provided, and its morphological characters are discussed. Neotrichoporoides Girault, 1913 in Iran, is represented by two species, N. szelenyii (Erdös, 1951) and N. viridimaculatus (Fullaway, 1955). Hereby, an identification key for Iranian species was provided. A worldwide distribution map of N. nyemitawus is also presented. Its role as the most important biocontrol agent of the shoot flies, Atherigona spp. (Diptera: Muscidae) was discussed. [ABSTRACT FROM AUTHOR]
