• Zatypota anomala

  Zatypota anomala is a koinobiont ichneumonid wasp in the tribe Ephialtini that parasitizes mesh web weaving spiders in the family Dictynidae. It is strictly specialized on Dictyna and Nigma spiders in Europe, with a distribution concentrated at mid-elevations in central European forest ecotones. The species exhibits elevation-dependent host partitioning, parasitizing Nigma at lower elevations (179–254 m a.s.l.) and Dictyna at higher elevations (361–870 m a.s.l.). First recorded from Italy in 2022, parasitizing Dictyna pusilla.
