Poecilosoma mongolica Konow, 1895: 75. Type locality: northern Mongolia “ Mongolia bor[ealis]”. Lectotype (here designated) Ψ: “N. Mongolei Leder 92 ” [white, printed]; “ Poecilosoma Mongolica Knw. Mongol. bor.” [white, framed, handwritten]; “ Typus ” [red, printed]; “ Holotypus ” (Sic!) [red, printed]; “Coll. Konow” [white, printed]; “Conde revid. 1937 ” [white, handwritten]; “GBIF-GISHym 3782 ” [white, printed]; “ LECTOTYPUS Poecilosoma mongolica KONOW, 1895 Ψ M.Heidemaa & M.Prous des.” [red, printed]; “ Empria mongolica (Konow, 1895) det. M.Prous 2008 ” [white, printed]; SDEI (see Notes).
Host plants. Dasiphora fruticosa (see Verzhutskii 1981).
Distribution. East - Palaearctic. The verified country records are: Mongolia, Russia (Kamchatka Krai, Irkutsk Oblast: Verzhutskii 1981). The record from arctic Norway (Kiaer 1898) is incorrect due to original misidentification of E. fletcheri specimens (determined by E. Lindqvist in 1948) as E. mongolica.
Key characters. Posterior margin of pronotum, small basal part or basal 1 / 3 of metatibia, and paired patches on abdominal terga 2–6 (7) unpigmented; tegulae largely unpigmented (females) or black (males). Ratio of flagellum length to head breadth in females 1.7 –2.0, in males 2.7–3.2, and eye length to head length in females 1.5–1.7, in males 1.7–2.2. Number of serrulae 14–15, conspicuously papilliform shaped (Fig. 37). Valviceps with a long basal lobe, forming relatively deep notch between valviceps and valvura (Fig. 54).
Notes. Oehlke & Wudowenz (1984) assumed that the only female of Poecilosoma mongolica Konow, 1895 found in Konow’s collection is the holotype but neither holotype was designated nor explicitly stated in the original description that there was only one specimen (thus a syntype).
