Remarks. This new species is similar to T. multimaculata Song & Li, 2008, which also has the same forewing color pattern and shape of style, but differs as follows: 1) abdominal apodemes small and not extending to 3rd segment; 2) aedeagus with two pairs of processes; 3) pygofer ventral appendage paddle shaped.

Biology This species hibernates under the bark of Zelkova serrata (Thunb.) Makino ( Rosales: Ulmaceae) in winter in Korea.

Etymology. The specific name is derived from the Latin adjective “ polymitus ” (colorful), which refers to the color pattern of the forewings (Fig. 4).
