674D87DFFFA0664A431BC70EBF4BFC58.taxon	discussion	Comments. Korneyev (1988) examined three specimens of this species from Armenia, with the following label data: Ararat Province, near Vedi Village, 3. VI. 1982, 1 female (Ermolenko coll.); near Vedi Village, Khosrov Natural Reserve, 27. VI. 1982, 2 females (Ermolenko coll.). Korneyev (1988) recognised these specimens as a new species in the Terellia virens group, but since all specimens were females, the description was postponed until the males were found. As a result, the description of T. freidbergi was published in the article revising the T. virens group (Korneyev et al., 2013). The Armenian specimens mentioned above, collected by Ermolenko and examined by Korneyev, were designated as paratypes of the species. It is important to supplement information that can be used to separate T. freidbergi from T. ivannikovi. The identification characters such as shape, position and colour of the elements of the scutal pattern are listed below. In 2013, one host plant of T. freidbergi was known, Centaurea behen L. It is now known that larvae of this species develop in capitula of various species of the genus Centaurea: C. kotschyi subsp. persica (Boiss.) Greuter (syn. Cheirolepis persica Boiss.), C. (Chartolepis) sp., C. polypodiifolia Boiss, C. daralagoezica (Fomin) Greuter (syn. Tomanthea daralaghezica (Fomin) Takhtajan) and C. spectabilis (Fisch. et C. A. Mey) Schultz Bipontinus (syn. T. spectabilis (Fisch. et C. A. Mey) Takhtajan). Host plants are illustrated in Figs 43 – 48 (see Addenda).	en	Evstigneev, D. A., Boyko, N. S.

674D87DFFFA2664E431BC690BEEBFC32.taxon	discussion	Comments. This species, previously known from Samara Province of Russia, is found in Saratov and Ul’yanovsk (northernmost location) provinces herein. Terellia ivannikovi was reared from its typical host plant, namely Centaurea chartolepis Greuter (syn. Chartolepis intermedia Boiss.) (Fig. 49; see Addenda). This species was also found for the first time from Armenia and Transcaucasia, with C. takhtajanii Gabrieljan et Tonjan being a new host plant.	en	Evstigneev, D. A., Boyko, N. S.

674D87DFFFA2664E431BC690BEEBFC32.taxon	description	Redescription. Medium-sized tephritid fly with general body colour greenish yellow. Body length: 4.7 – 5.7 mm in male, 5.0 – 7.0 mm in female. Thorax length 1.7 – 2.3 mm. Wing entirely hyaline, with yellow pterostigma. Distal portion of vein M twice as long as penultimate section. Scutal pattern with black and orange (ochreous) elements (Figs 16, 18). Median element of pattern: broad black stripe (vitta) bifurcated near its posterior end (median transsutural stripe bifurcated posteriorly). Lateral elements of pattern: a pair of short black oval patches located anterior to transverse suture (left and right presutural oval marks) and with two paired postsutural lateral stripes (black sublateral and orange lateral). Scutum with black spots at bases of prescutellar acrostichal setae (Figs 16, 18). Katepisternum and meron with intense orange (ochre) spots (Figs 24, 26). Male abdomen length 2 – 2.4 mm. Male abdominal tergite 5 with pairs of basal central (anteromedial), basal lateral (anterolateral) and apical lateral (lateroapical) black spots. Anteromedial spots large; anterolateral spots small. Anterolateral spots more often discernible in living specimens. Male abdominal tergites 3 – 4 with small anteromedial spots (often hardly discernible). In dried specimens, spots often discernible only on tergite 5: anteromedial and lateroapical or only lateroapical spots. Oviscape 2.6 – 2.8 times as long as tergite 6. All abdominal tergites combined 1.2 – 1.3 times as long as oviscape. Oviscape (= syntergosternite 7, = tergosternum 7, = seventh tergosternite) with dark setulae. Shape of aculeus typical for T. virens species – group. Aculeus length 2.0 – 2.4 mm. Variability. One aberrant male from Ul’yanovsk Province with extensive dirty ochre patch instead of narrow orange postsutural lateral stripe (Fig. 26). One male reared from C. takhtajanii with two medial stripes not completely fused with each other. This specimen demonstrates that the unpaired median stripe, which is typical of this species, is a result of fusion of two medial stripes. The female reared from C. takhtajanii has a typical unpaired median stripe (broad black stripe bifurcated near its posterior end).	en	Evstigneev, D. A., Boyko, N. S.
