Empria alpina Benson 1938

Description

Empria alpina Benson, 1938

Empria alpina Benson, 1938: 190 –191. Type locality: Scotland, Perthshire, Breadalbane Mountains, Crags above Lochan à Lairige [UK]. Holotype Ψ, BMNH [not examined, see Notes].

Host plants. Dryas octopetala (Veli Vikberg, personal communication).

Distribution. Holarctic (no Nearctic specimens were studied). The verified country records are: Finland, Germany, Great Britain, Italy, and Switzerland.

Key characters. Paired patches on abdominal terga 2–6 (7) unpigmented; tegulae, posterior margin of pronotum, and metatibia mostly black. Ratio of flagellum length to head breadth in females 1.6–2.1, in males 2.7–3.5, and eye length to head length 1.3–1.5. Number of serrulae 14, conspicuously papilliform (Fig. 36). Valviceps with a long basal lobe, forming very deep notch between valviceps and valvura (Fig. 53).

Notes. Taxonomic identity is evident from the original description (e.g. fig 7a in Benson, 1938), but confirmed also by studying three paratypes (1 Ψ and 1 ɗ with same collecting data as holotype).
