Tephritis anthrax S. Korneyev

et Evstigneev, 2019

( Figs 1–7 )

Material examined. Russia, Republic North Ossetia–Alania, Alagir Distr., environs of Verkhniy Tsey Vill ., along mountain stream, 1 female and 2 males reared 21.VIII.2020 from capitula of Cirsium sp. collected on 14.VIII.2020, coll. D.A. Evstigneev.

Distribution. Russia (Caucasus) and Armenia (S. Korneyev & Evstigneev, 2019).

Comments. This species was recently described from the North and western Caucasus (Karachay-Cherkessia and Adygea, respectively) and from Armenia. Here we provide the first data on T. anthrax from North Ossetia. The diagnostic characters of T. anthrax are illustrated in Figs 1–7 . The species is similar in several characters to the European species T. conura (Loew, 1844) . The morphological details of the latter species (male and female from the Middle Volga region, Ulyanovsk Province, European Russia) are illustrated in Figs 8–14 . These two species readily differ from each other in the wing pattern: in T. anthrax , the hyaline spot in the distal part of the cell r 4+5 near the apical margin of the wing is noticeably smaller ( Fig. 2 , a) than in T. conura ( Figs 8, a, 9 , a). The aculeus apex in both species is pointed ( Figs 7 , 12 ), without an apical incisura.
