Trupanea amoena (Frauenfeld, 1857)

( Figs 26–32)

Material examined. Armenia, Vayots Dzor Prov., between Mozrov Vill. and Arpi Vill., crumbling mountainside along dirty road, 2 females reared 19.VII.2018 from capitula of Reichardia dichotoma collected on 18.VII.2018 (coll. D.A. Evstigneev) . Russia, Republic of North Ossetia – Alania: nr. Vladikavkaz, ca. 2 km S of Chmi Vill., mountainside facing Suargom River , 4 females and 3 males reared 10.VIII.2020 from capitula of Reichardia dichotoma collected on 9.VIII.2020 (coll. D.A. Evstigneev) ; Western Digoria, Tana Glade bog, 1 km W of Kubus Mt., 42.89350°N 43.57733°E, 2077 m, 12.IX.2018, 1 female, sweep-netting (coll. A.A. Przhiboro) .

Distribution. Transpalaearctic species ( Merz, 1994).

Comments. Larvae of this species live in the capitula of a wide range of Asteraceae ( White, 1988; Merz, 1994; Freidberg & Kugler, 1989). Reichardia dichotoma (DC.) Freyn (syn. R. glauca Matthews ) is recorded for the first time as a host plant of T. amoena . Previously, another species of the genus Reichardia , R. picroides (L.) Roth, was recorded as a host plant for T. amoena in Italy ( Mazzon et al., 2008). The morphological details of T. amoena are illustrated in Figs 26–32. This species can be distinguished from the similar Trupanea stellata (Fuessly, 1775) by the following features of wing coloration ( Fig. 26): (1) brown ray on DM -Cu crossvein reaching posterior margin of wing (brown ray enclosing DM-Cu crossvein and apical part of Cu 1 vein); (2) narrow brown band extending from pterostigma to subapical area of cell br; (3) brown ray extending from subapical star-shaped spot towards vein C, and reaching vein C at level of crossvein R-M (it is necessary to draw a line through crossvein R-M and continue it towards vein C).
