title: First record of the monotypic genusAcanopsilusKieffer, 1908 (Hymenoptera: Diaprioidea: Diapriidae) from the Eastern Palaearctic region.
abstract: BACKGROUND
  The monotypic genusAcanopsilus(Hymenoptera: Diapriidae), is hitherto known only from Europe, where it is widely distributed.
  
  
  CONCLUSIONS
  The genus is here recorded for the first time from South Korea and China, which constitutes the first formal record of the species from the entire Eastern Palaearctic region. A detailed redescription and photographs ofAcanopsilus heterocerus(Haliday, 1857) are provided. Also,Acanopsilus brevinervisKieffer, 1909 is proposed as junior synonym ofAnommatium ashmeadiMayr, 1856 (syn. nov.).
