Figs. 13–30.

Type material. Holotype ♀: Iran: East Azerbaijan Province, Tabriz, University campus, 1440 m a. s. l., 23.vi.2015, swept from Amberboa sp. (Zarghani leg.) ( ICHMM).

Paratypes: 16 ♂, 6♀, same collection data as in the holotype (ICHMM, SIZK, and SMNC).

Description. Head ( Fig. 9 ): shape generally as described for T. amberboae ; HR = 1: 1–1.2: 1.45–1.6; frons length/width ratio 1–1.1; genal height / eye height of ratio 0.24–0.28. Flagellomere 1 with concave dorsal margin (Fig. 15). Palp pale yellow, moderately long, narrow.

Thorax (Figs. 13–14, 18–19) as described for T. amberboae .

Legs (Fig. 13, 15) as described for T. amberboae , orange-yellow, fore femur with two rows of posterodorsal yellow setae and one row of white posteroventral setae.

Wing: hyaline with pattern consisting of yellow pterostigma, and one dark brown spot at apex of vein R2+3 (Figs. 13, 14, 16), rarely in male with second, small dark brown spot on vein R2+3, at middle of cell r1 (Fig. 17); distal section of vein M 2.2–3.5 times as long as section between crossveins r-m and dm-cu; cell bcu (=cup) with short posteroapical lobe not reaching level of bm-cu crossvein. WL ♂ = 3.1–3.5 mm; WL ♀ = 3.5–3.9 mm.

Abdomen: yellow; all tergites white setulose, with yellow or brownish-yellow marginal setae; syntergite 1+2 with 1–2 pairs of small brown spots; tergites 3–5 (–6) each with 2 black spots mediobasally, wider than yellow area between them in both sexes (Figs. 19–20).

Male terminalia ( Figs. 22–26 ) as in A. amberboae : epandrium oval ( Fig. 22 ); lateral surstylus apicomedially densely papillose ( Fig. 24 , lower arrow); cerci papillose and wrinkled ( Fig. 24 , upper arrow); phallus glans ( Figs. 25–26 ) as in A. amberboae .

Female terminalia (Figs. 20–21, 27–30): oviscape yellow, with wide black spot dorsobasally; eversible membrane with short taeniae, with blunt, rounded, almost uniform scales (Figs. 20, 28); aculeus apically rounded, ( Fig. 30 , arrow); AL = 0.95–1.1 mm; AL/C2 = 1.45–1.65; spermathecae ( Fig. 27 ) as in T. amberboae .

Host plant. The larvae possibly develop in flower heads of Amberboa sp. ( Asteraceae : Asteroideae : Cardueae : Centaureinae ), along with larvae of Acanthiophilus helianthi (Rossi) .

Etymology. The species is named in honour of Dr. Hassan Barughi, an outstanding professor, in Department of Plant Protection, University of Tabriz.

Discussion. The new species can be distinguished from other species of Terellia by the combination of the following characters: acute first flagellomere, absence of black spots at the bases of scutal setae, lack of black lateral marks on abdominal sternites both in males and females, presence of large subquadrate black spot on mediodorsal part of abdominal tergites, all setae yellowish and all setulae white to yellow.

Terellia barughii most closely resembles Terellia amberboae , but can be differentiated by the wing pattern (one brownish spot at the end of vein R2+ 3 in T. barughii versus two pale spots beyond the pterostigma present in T. amberboae ). Additionally, the black abdominal spots in T. barughii are larger than in T. amberboae , and the aculeus tip is rounded (pointed in T. amberboae ).
