Crown wasps or Stephanidae are a family of parasitoid wasps that are noted for a semicircular to circular set of projections around the middle ocellus (simple eye), forming a "crown" on the head. The wasps are parasitoids of wood eating beetle larvae, mostly from the families Cerambycidae and Buprestidae, though some Curculionidae and occasional hymenopteran hosts are taken.
The new species Pseudomegischus notiochinensis was named after the country of origin, “notios” being Greek for “southern”.
For the experts: The genus Pseudomegischus van Achterberg, 2002, is newly reported from China. A new species, P. notiochinensis sp. n., is described and illustrated from southern China. A key to the species of Pseudomegischus is included.
