Pamphilius montanus pulcher Shinohara, 1988

( Figs 104 , 105 ) (https://doi.org/10.6084/m9.figshare.11405259)

Pamphilius pulcher Shinohara, 1988a: 311 ; Shinohara, 1991b: 113; Zhelochovtsev & Zinovjev, 1995: 398.

Pamphilius montanus pulcher: Shinohara, 2001: 106 , 113, 115; Shinohara, 2002b: 430; Shinohara & Lelej, 2007: 932, 940; Taeger et al., 2010: 89; Sundukov, 2017: 105; Lee et al., 2019: 10; Shinohara, 2019: 11; Shinohara, 2020: 14, 244.

Material examined. Sixty specimens, including the type series. Forty-three specimens are from South Korea ( Shinohara 1988b; present work). New collection data: SOUTH KOREA: Gangwon-do: 1♂ ( NSMT 30749), Mirugam (Bukdaesa), 1300m, Odaesan Mts., 26. V. 2008, A. Shinohara ( NSMT); 1♂ ( NSMT 30853), same locality, 2. VI. 2009, A. Shinohara ( NSMT). See Shinohara (1988 a, 2001) for more collection data.

Distribution. Russia (Yakutia), South Korea, Japan (Hokkaido) ( Shinohara 2001).

Host plant. Unknown.

Remarks. This is a member of the P. sylvaticus group defined by Shinohara (1985 a, 2002b). Shinohara (1988a) described this subspecies as a full species but Shinohara (2001) treated it as a subspecies of P. montanus Shinohara, 1985 .

In our molecular analysis, the maximum intrasubspecific p -distance among specimens from Korea and Hokkaido, Japan, was 1.5% in COI (n=4) and 0.2% in NaK (n=3). The minimum distance to the specimens of the nominotypical P. montanus montanus from Honshu, Japan, was 3.7% in COI and 0.1% in NaK. The nearest neighbour was P. volatilis , diverging by a minimum of 4.1% in the COI analysis, and P. alnicola , diverging by a minimum of 0.6% in the NaK analysis. In the COI tree ( Fig. 145 ), each of P. montanus , P. m. montanus and P. m. pulcher was retrieved as monophyletic with UFBoot support of 100% and P. montanus was sister to P. alnicola with UFBoot support of 82%. In the NaK tree ( Fig. 159 ), P. m. montanus (n=2) was retrieved as monophyletic with UFBoot support of 100%, but P. m. pulcher (n=3) was not, while all the specimens of P. montanus (n=5) formed a clade with UFBoot support of 93% and the clade consisting of P. gracilis and P. graciloides was retrieved as sister to P. montanus with very low UFBoot support of 70%.

Pamphilius montanus pulcher is probably associated with Sorbus (Rosaceae) because the larvae of the nominotypical subspecies from Honshu, Japan, are gregarious web-spinners on Sorbus commixta Hedl. (Rosaceae) ( Shinohara & Kojima 2011).
