Distribution. Finland, Russia (Yakutia) (Shinohara & Vasilenko 2005). South Korea (new record).
Host plant. Rosaceae: Sorbus aucuparia L.
Remarks. This is a rare species previously known only from Finland and Yakutia, Russia (Shinohara & Vasilenko 2005). This is the first record from Korea. The larvae are gregarious web-spinners on Sorbus (Vikberg 2002). Another species of Pamphilius, whose larvae are gregarious web-spinners on Sorbus, is P. montanus montanus Shinohara, 1985, from Honshu, Japan (Shinohara & Kojima 2011). The larvae of these two species have not been differentiated.
The Korean specimens examined differ from the Finnish specimens in a darker colour pattern. In Korean females, the entire tergum 1, large areas on the terga 2 and 6 and the entire terga 7 and 8 are black and all the sterna are broadly black basally. In Finnish females, the entire tergum 1 and very narrow areas on the terga 2 and 6 to 8 are black and the sterna 2, 3, 6 and 7 are marked with black basally. In almost all males from Korea, the postocular stripe terminates at the corner of the upper inner orbits, whereas the postocular stripe extends ventrally along the inner orbits in the Finnish males (see fig. 2 in Vikberg 1971). In structural characters, no conspicuous differences have been found.
In our molecular analysis, the maximum intraspecific p -distance was 1.3% in COI (n=4) and 0.1% in NaK (n=4). The nearest neighbour was P. balteatus (Fallén, 1808), diverging by a minimum of 3.7% in the COI analysis, and P. confusus Shinohara, 2005, diverging by a minimum of 0.4%, in the NaK analysis. In the COI tree (Fig. 151), P. aucupariae branched off near the base of the P. vafer group and its affinities are unclear, whereas in the NaK tree (Fig. 161) it was retrieved as sister to P. leleji with UFBoot support of 98%.
