Halyomorpha halys is an invasive, widespread stink bug for which only short-term solutions are currently available for pest control worldwide. The need for long-term management solutions for H. halys has driven studies on augmentative and classical biological control of this species, especially by its egg parasitoids. Numerous investigations in Asia, USA, and Europe on native and exotic egg parasitoids of H. halys, and the effects on non-target pentatomids, have improved the global knowledge of parasitoid-host relationships, uncovered new associations, and led to the discovery of new species. This trend continues with Acroclisoides sinicus, a pteromalid that was described in the 1980’s from Asia. In this work we report recent findings of this species in North America and Europe. Moreover, we propose that Acroclisoides solus syn. nov., a species described originally from the USA, is conspecific with A. sinicus based on morphological and molecular analysis.
