Carpenter-moths (Lepidoptera, Cossidae) of the Korean peninsula with a new record of species

We present eight species in seven genera of the family Cossidae (Lepidoptera) from Korea, including one newly recorded species, Cossus siniaevi. Two females of C. siniaevi were collected in the middle part of Korea, and they were distinguished by the strongly elongate forewing with narrow wavy black streaks and a weakly grayish-white patch in the medial zone and at the apex. The female genitalia of C. siniaevi can be distinguished by the simple antrum simple with medially invaginated, the short and narrow ductus bursae, and the large pouch-shaped corpus bursae without a signum. We provided the diagnosis of each genus, including male and female genitalia, and the key to the species.
