Pamphilius rhoae Shinohara 1988b: 188; Kim et al., 1994: 217; Shinohara & Lee, 1997: 218; Shinohara, 2002b: 427; Shinohara, 2004: 264; Paek et al., 2010: 161; Taeger et al., 2010: 90; Lee et al., 2019: 10; Shinohara & Tripotin, 2021: 62; Shinohara & Tripotin 2021b: 197.

Material examined. Seventy-two specimens, including the type series, all from South Korea (Shinohara 1988b; Shinohara & Lee 1997; Shinohara & Tripotin 2021a, b; present work). New collection data: SOUTH KOREA: Gangwon-do: 1♀, Tokchomgogae, 510m, nr. Chuncheon, 22. V . 1992, A. Shinohara (NSMT); 1♀, Sangwonsa, Odaesan Mts., 20. V . 1989, A. Shinohara (NSMT); 1♀ (NSMT 30858), same locality, 6. VI . 2009, A. Shinohara (NSMT); 1♀, Mirugam (Bukdaesa), 1300m, Odaesan Mts., 6. VI . 1996, J.-W. Kim (NSMT).

Distribution. South Korea.

Host plant. Unknown.

Remarks. This Korean species belongs to the P. thorwaldi complex of the P. stramineipes subgroup of the P. vafer group (Shinohara 2002b). It is very close to P. planifrons from Primorskij Kraj in morphology and genetics (Figs 149, 161). Although most of the known specimens can be identified by the characters given in the key, the two species may eventually be treated as local forms of the same species. Before synonymizing them, however, we still need more information about geographical variations and preferably also host plants and immature stages.
