Empria loktini Ermolenko, 1971

Empria loktini Ermolenko, 1971: 22 –23. Type locality: Novoaleksandrovsk [Sakhalin Oblast, Russia]. Holotype Ψ, (SIZ) [examined].

Host plants. Unknown, but the adults have been collected from Filipendula kamtschatica (see Ermolenko 1971) and at least some of the Japanese specimens have been collected from the localities where this plant species is common (A. Shinohara, personal communication).

Distribution. East - Palaearctic. The verified country records are: Japan (Hokkaido) and Russia (Sakhalin Oblast).

Key characters. Posterior margin of pronotum, metatibia in basal 1/3, and paired patches on abdominal terga 2–3 or 2–4 (5) unpigmented; tegulae unpigmented (females) or black (males). Ratio of flagellum length to head breadth in females 1.8–1.9, in males 2.3–2.4, and eye length to head length in females 1.2–1.7, in males 1.5–2.0. Number of serrulae 13–14 (15), triangular in shape ( Fig. 39 ). Penis valve with relatively large apical tooth and apical part of valvular duct going clearly further from dorsal rim of valvura; valviceps with medium sized lobe, forming a notch between valviceps and valvura ( Fig. 55 ).

Notes. The paratypes 1 Ψ 2 ɗ (1 ɗ labelled as allotype) were also studied.
