Pamphilius alnicola Ermolenko, 1973: 24 ; Beneš, 1977: 263; Shinohara, 1985a: 327; Shinohara, 1988a: 318; Shinohara & Hara, 1993: 546; Shinohara & Hara, 2005: 274; Zhelochovtsev & Zinovjev, 1995: 397; Shinohara, 2001: 113, 115; Shinohara, 2002a: 189; Shinohara, 2002b: 429; Shinohara, 2004: 265; Shinohara & Hara, 2005: 274; Shinohara & Lelej, 2007: 931, 940; Taeger et al., 2010: 86; Sundukov & Lelej, 2012: 108; Sundukov, 2017: 104; Shinohara, 2019: 8; Shinohara, 2020: 14, 244.

“ P. sp. n.”: Beneš, 1974: 313.

Material examined. About 85 specimens, including one specimen from the Russian Far East ( Shinohara 1988a).

Distribution. Russia (Primorskij Kraj), Japan (Hokkaido, Shikotan Is., Honshu) ( Shinohara 1988a).

Host plant. Betulaceae : Alnus hirsuta (Spach) Turcz. ex Rupr. ( Shinohara & Hara 1993, 2005).

Remarks. Shinohara (1988a) gave a collection record of one female specimen from Primorskij Kraj (Tedjuche = Dal’negorsk district) and no additional specimens have been available from the continent. The species is uncommon throughout its distribution range. The larvae are gregarious leaf rollers on Alnus ( Shinohara & Hara 1993) .

This is a member of the P. sylvaticus group ( Shinohara 1985 a, 1988 a, 2001, 2002b). The maximum intraspecific p -distance within P. alnicola is 0.5% in COI (n=2) and 0.1% in NaK (n=2). Pamphilius alnicola was retrieved as the sister of P. montanus Shinohara, 1985 , with UFBoot support of 82% in the COI tree ( Fig. 145 ), whereas it was retrieved as the sister of the clade consisting of P. benesi Shinohara, 1985 , P. pallidus Shinohara, 1988 , P. volatilis ( Smith, 1874) , P. gracilis Shinohara, 1985 , P. graciloides sp. nov. and P. montanus with UFBoot support of 99% in the NaK tree ( Fig. 159 ). In the distance data, the nearest neighbour of P. alnicola was P. volatilis , diverging by a minimum of 4.9% in the COI analysis and P. montanus and P. volatilis by a minimum of 0.6% in the NaK analysis.
