Empria alector Benson, 1938

Empria alector Benson, 1938: 191 –192. Type locality: Scotland, Moray, Grantown [ UK]. Holotype Ψ, BMNH [not examined, see Notes].

Empria waldstaetterense Liston, 1980: 225 –227. Type locality: Altzellen-St.Joder, Nidwalden, Switzerland. Holotype Ψ, RSME [examined, see Notes], syn. nov.

Host plants. Filipendula ulmaria .

Distribution. West-Palaearctic. The verified country records are: Denmark, Estonia, Finland, France, Germany, Great Britain, Russia (Leningrad Oblast), Sweden, and Switzerland (complete record in the file http:// empriini.myspecies.info/files/imports/long_group_spec.txt).

Key characters. Posterior margin of pronotum and paired patches on abdominal terga 2–5 (6) unpigmented; tegulae and metatibia in basal 1/3 black, sometimes partly unpigmented. Ratio of flagellum length to head breadth in females 1.8–2.1, in males mostly 2.8–3.3, and eye length to head length 1.6–2.0. Number of serrulae (16) 17–18, with its ventral margins almost at the same level along its entire length ( Fig. 43 ). Valviceps with medium sized lobe, forming a notch between valviceps and valvura ( Figs 51 , 56 ); valvura to valviceps length ratio mostly 0.6– 0.7.

Notes. Taxonomic identity is evident from the original description (e.g. fig 7c in Benson, 1938). Empria waldstaetterense Liston, 1980 (see Morphbank images id=579042–579045) was incorrectly synonymized with E. sexpunctata (Serville, 1823) by Liston (1995), under the name E. klugii (Stephens, 1835) at that time.
