Empria longicornis ( Thomson, 1871)

Poecilosoma longicornis Thomson, 1871: 232 . Type locality [original description]: Skåne [Southern Sweden]. Lectotype (here designated) Ψ: “ZML 2006 362” [pale, printed]; “ LECTOTYPUS 2009 Poecilosoma longicornis THOMSON, 1871 M.Heidemaa & M.Prous design.” [red, printed]; “ Empria longicornis ( Thomson, 1871) det. M.Prous 2007” [white, printed]; paralectotypes (representing different Empria spp.): 8 Ψ and 2 ɗ; all ZML.

Empria rubi Kontuniemi, 1951: 24 –27. Type locality [from label]: Pernaja, Suomi U. [ Finland, “U.” refers to Uusimaa District]. Holotype Ψ, ZMH [examined, see Notes].

Host plants. Rubus idaeus . Filipendula ulmaria (see Kontuniemi 1951) and Fragaria vesca (see Zhelochovtsev & Zinovjev 1988) were not confirmed as preferred host plants for E. longicornis ( Table 7 ).

Distribution. Palaearctic. The verified country records are: Denmark, Estonia, Finland, France, Germany, Hungary, Romania, Slovakia, Sweden, and Switzerland. The record from Mongolia ( Zombori 1972) is incorrect due to misidentification of several E. mongolica males as E. longicornis .

Key characters. Posterior margin of pronotum and paired patches on abdominal terga 2–4 or 2–5 (6) (mostly males) unpigmented; tegulae and metatibia in basal 1/3 black, sometimes partly unpigmented. Ratio of flagellum length to head breadth in females mostly 2.3–2.7, in males mostly 3.1–3.8, and eye length to head length 1.7–2.2. Number of serrulae 16–17 (18), triangular in shape ( Figs 41 , 46 ). Valviceps with short lobe, forming inconspicuous notch between valviceps and valvura ( Fig. 48 ); valvura to valviceps length ratio mostly 0.45–0.56.

Notes. The type specimens of Empria rubi Kontuniemi, 1951 (2 Ψ, 2 ɗ) were reared from larvae (holotype Ψ, 2 paratypes Ψ and ɗ [labelled as allotype]) or ex ovo (paratype ɗ) by T. Kontuniemi.
