( Figs 115 , 116 ) (https://doi.org/10.6084/m9.figshare.11405283)

Lyda sapporensis Matsumura, 1912: 80 ; Takeuchi, 1930: 9 (syn. of P. venustus ( Smith, 1874)) .

Pamphilius rugosus Beneš, 1976: 165 ; Shinohara & Okutani, 1983: 278 (syn. of P. sapporensis ).

Lectotype designation. Matsumura (1912) described Lyda sapporensis without giving number of the specimens examined. Here we designate the male specimen labeled “Sahoro, 6/5” “29” “ Lyda sapporensis n. sp. det. Matsumura ” in Matsumura’s collection ( HU) as a lectotype. It is in poor condition and has the head and genitalia missing.

Material examined. About 545 specimens, including the lectotype, and two specimens from the Russian Far East ( Shinohara 2002b; Shinohara & Taeger 2007).

Distribution. Russia (Sakhalin), Japan (Hokkaido, Shikotan Is.) ( Shinohara & Taeger 2007).

Host plant. Rosaceae : Filipendula camtschatica (Pall.) Maxim. ( Shinohara & Okutani 1983).

Remarks. Shinohara (2002b) placed this species in his P. venustus complex of the P. stramineipes subgroup of the P. vafer group. Pamphilius sapporensis has much in common with P. venustus in morphology, molecular data (see below) and host plants, and overlapping distributions of the two species in Hokkaido is interesting in clarifying their speciation history. The maximum intraspecific p -distance among the three Japanese specimens in P. sapporensis was 0.3% in COI and 0.1% in NaK and the nearest neighbour was P. balteatus , diverging by a minimum of 2.5% in the COI analysis, and P. venustus by a minimum of 0.8% in the NaK analysis. In the COI tree ( Fig. 149 ), the relationship of P. sapporensis with other species was not well resolved, but in the NaK tree ( Fig. 161 ), P. sapporensis was retrieved as the sister of P. venustus with 99% UFBoot support.

In Hokkaido, Japan, this species occurs together with two other Filipendula -associated pamphiliids, P. venustus (known from Hokkaido, Honshu and Shikoku) and Onycholyda kumamotonis (known from Sakhalin, Hokkaido, Kunashiri Is., Honshu and?Kyushu). The largely orange upper part of head will easily distinguish P. sapporensis from the latter two species.
