Number: 274, Pages: 1 - 59
The Palaearctic species of the fairyfly wasp genus Cleruchus Enock, 1909 (Hymenoptera: Mymaridae) are reviewed, and a key to both sexes is given. Three new taxa are described: C. kivach sp. n. (Karelia, Russia), C. nikaknet sp. n. (Italy), and C. taktochno sp. n. (Belgium). Also described and illustrated is the previously unknown male of C. petr Triapitsyn, 2002 (Far East of Russia). Cleruchus bakkendorfi Debauche, 1948, syn. n. is synonymized under C. pluteus Enock, 1909, the type species of the genus, for which a lectotype is designated. Cleruchus terebrator (Ogloblin, 1959) and C. vagatus (Ogloblin, 1959), both from Argentina, are transferred to Platystethynium Ogloblin, 1946 as, respectively, P. terebrator (Ogloblin), comb. n. and P. vagatus (Ogloblin), comb. n. Cleruchus terebrator Viggiani, 1970, stat. rev. (Switzerland) is reestablished as the proper name since its replacement name C. europaensis Özdikmen, 2011, syn. n. became unnecessary.
