Vanhornia yurii Timokhov & Belokobylskij 2020

Vanhornia yurii Timokhov & Belokobylskij, 2020 (Figs. 7A–F) Vanhornia eucnemidarum: Choi & Lee, 2012: 60. Misidentification. Vanhornia yurii Timokhov & Belokobylskij, 2020: 60–67. Holotype (not examined): female; type locality: Lazovskiy Natural Reserve, Russia. Diagnosis. Frontal transverse carina absent; apical margin of labrum straight. Scutoscutellar sulcus with seven foveae; mesodiscrimen with about 10 strong foveae; median longitudinal carina on dorsal part of propodeum present; smooth area on postero-lateral part of propodeum present. Vein Rs+M not connected to Cu. Syntergite with longitudinal ridges, reaching to a maximum of 0.4 length of syntergite, touching first thyridium; antero-dorsal margin of syntergite almost straight. Non-types. South Korea: 1f (recorded as V. eucnemidarum in Choi & Lee (2012)), GB (Gyeongsangbuk-do), Chongdo-gun, Unmun-myeon, Mt. Unmun, 35°38’50’’N, 128°58’29’’E, MT, 30 V–16 VI 2009, J.W. Lee (YNU). Japan: [Hokkaido] 3f (22–29 VI 2010), 1f (29 VI –6 VII 2010), 1f (6–13 VII 2010), and 2f (27 VI –4 VII 2011), Sapporo, Hitsujigaoka, 43°00’09” N 141°24’56” E, MT, K. Konishi (ELKU); 1f, Sapporo, Mt. Maruyama, 43°02’N 141°18’E, 6 VII 2017, Juriya Okayasu (SEHU); 1f, Oketo Town, Tsunemoto, 43.6050N 143.3440E, 3 VIII 2013, R. Matsumoto (OMNH). [Honshu] Hyogo Pref., Odanganaru, Mt. Hyono-sen, 35°20’N 134°31’E, 21 VII 2012, K. Watanabe & Y. Kanno (KPMNH). Host. Unknown. Distribution. Japan (new record), Russia (Timokhov & Belokobylskij 2020), South Korea (new record). Remarks. Timokhov & Belokobylskij (2020) suggested that the South Korean record of V. eucnemidarum needed to be reconfirmed. We examined the voucher specimen of this record and photographs in Choi & Lee (2012) and identified the species from South Korea as V. yurii. The morphological variations were recognized as follows: median longitudinal sulcus on vertex sometimes present, but weak; foveae on notauli sometimes fused posteriorly; syntergite 1.96–2.4 times as long as its maximum width in dorsal view; length of ovipositor 1.1–1.9 times as long as metasoma in lateral view (normally reaching to around pronotum, but sometimes not reaching to middle coxa). The specimen from Oketo Town, Hokkaido, Japan was collected near some logs in the forest (Fig. 5). The specimen from Hyogo Prefecture, Japan was found at night on a dead walnut tree (K. Watanabe pers. com.).
