Specimens examined. South Korea : Gyeonggi-do : 35♂ , 16♀ , Anyang-si , SNU Gwanak Arboretum , 9.vii.2008 , on Wisteria floribunda (Willd.) DC. (Fabaceae), R . K. Duwal and S. Jung (SNU) . Distribution. Japan ( Hokkaido , Honshu, Shikoku, Kyushu), Korea (South). Discussion. In Japan , this species has been collected on various host plants belonging to families Eriaceae, Fagaceae , Cupressaceae , Pinaceae , and Cephalotaxaceae , and nymphs were also observed on azalea ( Yasunaga 1999 ). In this study, Korean Atractotomoidea was observed on blue flowering woody liana, Wisteria floribunda (Willd.) DC. (Fabaceae) in summer and confirmed one generation per year in Korea .
