039187BFED61241B11C1FD0BB8FEC14A.taxon	discussion	Remarks. The examined external morphological features and DNA sequence data support the allospecificity of Idiotypa maritima (Haliday) and I. mariae Gregor. Both species are widely distributed in Palaearctic from West Europe to Japan. Examination of the type material, the lectotype of I. nigriceps Kieffer, 1909 (the same specimen also the lectotype of I. nigriceps Kieffer, 1911), the lectotype of I. rufiventris (Thomson), and the lectotype of I. maritima (Haliday), clearly shows that these names are synonyms. The species Eunuchopria nitens Szabó, 1961, originally described in the monotypic genus Eunuchopria (Szabó, 1961), appears at first sight very different from Idiotypa, most noticeably by its aptery in both sexes, lack of ocelli, notauli, tegulae, axillae and axillar depressions; scutellum only visible as narrow transverse sclerite with only scutoscutellar sulcus between it and mesoscutum. However this is an expression of a common suite of reduction characters associated with extreme wing reduction and fossorial habits, which appears to have arisen commonly in several unrelated genera of diapriines. Similar extreme examples can be found in some undescribed species of Idiotypa from Chile and Argentina (Masner & Garcia, 2002), Spilomicrus myrmecophilus Nixon (females) and Platymischus dilatatus Westwood (both sexes). If these particular reductions are discounted the remaining features of E. nitens correspond well with diagnosis of the genus Idiotypa. We therefore consider E. nitens is simply a highly derived species of Idiotypa and Eunuchopria Szabó, 1961 is therefore a junior synonym of Idiotypa Förster, 1856. Unfortunately the diagnostic characters of the species of Idiotypa are not universal in all parts of the Palaearctic region. The key below works well for the fauna of Europe (including the European part of Russia), Siberia and Russian Far East. While antennal characters of female I. maritima and I. mariae are difficult to appreciate, in combination with characters of the mesopleural sculpture and body colour, they can be used to make reliable determinations, however in Japan no combination of characters is consistent for species recognition.	en	Chemyreva, Vasilisa G., Notton, David G., Zaldívar-Riverón, Alejandro (2021): Revision of Palaearctic Idiotypa (Hymenoptera, Diapriidae, Diapriinae, Spilomicrini).
