NEW GENERA, NEW SPECIES OF CHINESE PENTATOMIDAE AND A NEW CHINESE RECORD OF SCUTELLERIDAE (HETEROPTERA)

Three new genera, seven new species of Penlatomidae from China are described in this p醦er. Poecilocoris baltcatus (Distant) (Scutellcridae), Nevisanus nagaensis Distant and Glau-cias nigromarginatus Stal (Pentatomidae) are recorded as new to China. The genus Acicazira Hsiao et Cheng 1977 is synonymized with subgenus Teratocazira Breddin 1903 of Cazira; Acica-zira gibbosa Hsiao a Cheng 1977 is synonymized with Cazira (Teratocazira) horvathi Breddin 1903. All the type specimens are deposited in Nankai University except otherwise stated.
