Onycholyda sp. : Shinohara & Okutani, 1983: 277.

Lectotype designation. Shinohara (1985d) treated a specimen in Matsumura’s collection in HU as the holotype, stating “ Matsumura (1912) described this species on the basis of a single female from Kiushu (Kumamoto)”. However, Matsumura (1912) did not give the actual number of the specimens examined and thus the specimen is a syntype. Here we designate this specimen as a lectotype. It is labeled “ Japan, Kumamoto, Matsumura, 7/18” (HU).

Material examined. About 355 specimens, including the lectotype. Two specimens are from the Russian Far East ( Shinohara 1985d).

Distribution. Russia (Sakhalin), Japan (Hokkaido, Kunashiri Is., Honshu,?Kyushu).

Host plant. Rosaceae : Filipendula camtschatica (Pall.) Maxim. ( Shinohara & Okutani 1983; Shinohara 1985c).

Remarks. This species is not rare around Filipendula camtschatica bushes in Hokkaido, where two species of Pamphilius , P. venustus ( Smith, 1874) and P. sapporensis ( Matsumura, 1912) also occur together. These three pamphiliids are all associated with Filipendula .

In the COI analysis ( Fig. 139 ), three specimens from Hokkaido (NSMT30554, 30788, 30789) and four specimens from Honshu (NSMT30730, 30785–30787) each formed a different cluster and the two clusters had a sistergroup relationship supported by 100% UFBoot values. The maximum p -distance in the Hokkaido cluster was 0.2% and that in the Honshu cluster was 1%. The minimum p -distance between the Honshu and Hokkaido clusters was 2.2%. In the NaK tree ( Fig. 153 ), the four Honshu specimens formed a cluster but the three Hokkaido specimens did not and, with the Honshu cluster, formed a polytomous clade, which was sister to O. armata (this clade, O. kumamotonis + O. armata , was supported by 100% UFBoot value). The maximum p -distance within O. kumamotonis was 0.4% and the nearest neighbour, diverging by a minimum of 0.2%, was O. armata . The Hokkaido and Honshu populations of O. kumamotonis certainly have some genetic divergence, but we will leave them as one species until more evidence of speciation becomes available.
