Empria minuta Lindqvist, 1968

Empria minuta Lindqvist, 1968: 30 . Type locality: vicinity of Helsinki [original description] “Umgegend von Helsingfors” [ Finland], “N. Helsinge” [from label]. Holotype Ψ, ZMH [examined].

Empria gussakovskii auct. nec Dovnar-Zapolskij, 1929.

Host plants. Unknown.

Distribution. Palaearctic. The verified country records are: Estonia, Finland, Mongolia, Russia (Leningrad Oblast, Yamalo-Nenets Autonomous Okrug), and possibly Sweden (the specimen UUZM_HS).

Key characters. Tegulae partly or largely, posterior margin of pronotum, metatibia in basal 1/3, and paired patches on abdominal terga 2–6 unpigmented. Ratio of flagellum length to head breadth in females 1.8–2.1, in males 2.8–3.0, and eye length to head length in females 1.6–1.7, in males 1.7–2.1. Number of serrulae 14–16, slightly papilliform shaped ( Fig. 38 ). Valviceps with medium sized lobe, forming a notch between valviceps and valvura ( Fig. 58 ); valvura to valviceps length ratio 0.63–0.72.

Notes. There is no information about the locality and the collector of the female specimen from UUZM, but it has probably been collected from Sweden. The flight period of the adults might partly explain why this species has been collected rarely. The Estonian specimens were found in a Malaise trap only between 12–30 April (3 ɗ) and 30 April – 15 May 2010 (1 Ψ).
