Pamphilius daisenus Takeuchi, 1938: 221; Shinohara, 1985a: 332; Shinohara, 1988a: 319; Shinohara, 2001: 109, 114, 115; Shinohara, 2002b: 430; Shinohara, 2004: 265; Taeger et al., 2010: 86; Shinohara et al., 2016b: 123; Lee et al., 2019: 9; Shinohara, 2019: 9; Shinohara, 2020: 16, 246; Shinohara & Tripotin 2021b: 197.

Material examined. Twenty-one specimens, including the holotype. Two specimens are from South Korea (Shinohara 2001; Shinohara & Tripotin 2021b).

Distribution. South Korea, Japan (Honshu) (Shinohara 2001).

Host plant. Rosaceae: Aruncus dioicus (Walter) Fernald var. kamtschaticus (Maxim.) H. Hara, Spiraea japonica L.f. (Shinohara et al. 2016b).

Remarks. This species was described from Honshu, Japan (Takeuchi 1938) and later recorded from Korea (Shinohara 2001; Shinohara & Tripotin 2021b). The larvae are oligophagous solitary leaf-rollers on Aruncus and Spiraea (Rosaceae) in Japan (Shinohara et al. 2016b). Molecular data are not available from the Korean specimens, but the eight COI sequences from the Japanese material formed a clade which was sister to P. gracilis + P. graciloides with 98 % UFBoot support (Fig. 145), diverging by a minimum of 4.9 % from both species.
