Brachyusa concolor (Erichson, 1839)

(Figs 70a–e)

Material examined. 1 ♂ (Fig. 70a; aedeagus in lateral view as in Fig. 70b; labels as in Fig. 70c): ‘ T. sulcata K. Hochh. ’, ‘ Lectotypus ♂ Tachyusa sulcata Hochhuth V. Gusarov des. 1991’, ‘ ♂ Brachyusa concolor (Er.) V. Gusarov det. 1991’, ‘Staph 2’; 1 ♂ (Fig. 70d; labels as in Fig. 70e): ‘ Paralectotypus ♂ Tachyusa sulcata Hochhuth V. Gusarov des. 1991’, ‘removed from the lectotype pin V. Gusarov’, ‘ ♂ Brachyusa concolor (Er.) V. Gusarov det. 1991’, ‘Staph 1’.

Remarks. Hochhuth (1871) recorded Tachyusa sulcata Kiesenwetter, 1850 from Ukraine (“…Flüsschen Lebbedj”). Gusarov studied these specimens in 1991, and identified them as B. concolor (Erichson, 1839), a widespread species in the western Palaearctic Region (Schülke & Smetana 2015). The designation of the lectototype was the result of a confusion.
