Catocala naganoi Sugi, 1982, Tyo to Ga, 32(3–4), 147–159, (TL: Taiwan, Taoyuan Hsien [HT: coll. NSMT, Tokyo).

This species appears to be endemic to Taiwan, where it is recorded from Taoyuan (Fig 1: H & K–L) and Hsinchu Counties (Figure 1: I–J). The holotype of C. naganoi (Sugi 1982, Fig. 5) is typical in wing pattern to material we studied, and the valvae (Sugi 1982, Fig. 12) are similar to our dissections except for the left clasper, which appears to have been damaged and bent by ca. 180 degrees as a result of slide mounting.
