摘要: A new species of Trissolcus Ashmead (Hymenoptera: Scelionidae), halyomorphae Yang, sp. nov., is described from China. It a solitary parasitoid in eggs Halyomorpha halys (Stal) (Hemiptera: Pentatomidae), an economic pest that causes severe damage to pear, apple and other fruit also feeds on the leaves stems ornamental forest trees.
