[3]: dimorpha Kwon & Lee; montana Kato ; testacea Cai & Kuoh. Range. Taiwan ( Chiayi Hsien : Alishan; Mt. Niitaka ; Nantou Hsien : Tungpu; Taichung : Anmanshan; Tainan ); Korea Host plants. Unknown. Material examined. P. testacea : 1 male , 1 female , Taiwan , TARI , JRJ _Led1_272–273; Parapetalocephala sp .: 1 female , Taiwan , TARI , JRJ _Led1_467 . Remarks. Two specimens of Parapetalocephala testacea were identified from material obtained from TARI, and were used in this analysis. A third unidentified specimen of Parapetalocephala from TARI was also briefly examined. The cells of the forewing appear to vary in their degree of depression between the two species examined, with P. testacea having more deeply depressed cells.
