Description. Head (Fig. 2). All part of head yellow except ocellar triangle brown to black. Antenna yellow, scape with six to eight blackish setulae at dorso-apical margin; first flagellomere light yellow, 1.8 times as long as wide and distinctly rounded apicodorsally; arista very short pubescent, yellow at base and black in its slender part. Proboscis capitate with brown setulae. Three frontal and two orbital setae present. Postocular and postgenal setae white and genal yellowish; Subvibrissal setae black.
Thorax. Yellow in ground color. Scutum with black lyrate pattern, densely covered by white microtrichia and three pairs of shining black spots: one pair at suture and 2 pairs bases of dorsocentral and prescutellar acrostichal setae. Pleuron yellow; only triangular mark on katepisternum and meron black, obscured by gray microtrichia; scutellum yellow; subscutellum and mediotergite black. All setae on thorax yellowish brown. Scutellum with 2 pairs of black setae (apical 0.7 as long as basal one), slightly convex, without dark spots. Halter yellow. Legs completely yellow, without modifications; fore femur with 10 long yellow posterior and 4 brownish ventral setae; setulae brownish.
Wing (Fig. 1). Hyaline with pattern of 4 well developed yellow to brownish crossbands, in general, similar to T. tarbinskiorum Korneyev 2006; wing base and alula yellowish; subbasal crossband reaching from costal cell to A1+CuA2 vein. Discal crossband complete, crossing wing from pterostigma through r-m crossvein into cua1 cell. Preapical band complete, reaching to posterior margin. Subbasal and discal crossbands fused in r1 cell; preapical and apical crossbands widely separated: hyaline interval between them along R2+3 vein as wide as preapical crossband. Setae on dorsal side of vein R1 without gap at Sc apex level. Vein R4+5 bare.
Abdomen. General color dark yellow; setulae mostly white, black on posteromedial portion of male tergite 5. Tergites 4–6 in female with two pairs of black spots at anterior margin and tergite 3 with only one pair of such spots. Tergites 4–5 in male with two pairs of spots and tergite 3 with only one pair of spots at anterior margin. In addition, tergite 5 with one pair of posterior spots. Marginal setae on female tergites 5–6 pale brown; tergite 5 of male 0.3 times as long as abdomen.
Male terminalia. Epandrium and hypandrium as in other species of this group. Glans as in Fig. 5, large, with wide tubular base of acrophallus and rather long apical semitubular lobes, wall of preputium sclerotized only dorsally.
Female terminalia. Oviscape yellow, about as long as preceding 3 abdominal tergites. Aculeus (Figs. 3–4) rather bluntly pointed, its apex 1.3 times as long as wide, with 3 pairs of subapical trichoid sensilla and pair of rather large campaniform sensilla. Aculeus length/width ratio = 4.2. Two papillose spermathecae as in T. tarbinskiorum.
Measurements. WL 3 = 2.8–3.7 mm (average 3.2); WL Ƥ = 3–3.8 mm; (average 3.6); AL = 0.7–0.9 mm (average 0.75); AL/C2 = 0.7–0.9 (average 0.76) (n = 5).
Discussion. Terellia korneyevorum sp. nov. is very similar to two other species of this group in male and female genitalia structure differing mainly by wing pattern details. In T. korneyevorum sp. nov., the apical and preapical crossbands are separated at anterior margin of the wing and discal and preapical crossbands are narrower compared to the other two species. These characters are constant in the type specimens collected in geographically distant Yazd and Kurdistan provinces of Iran showing no intermediate conditions.
Etymology. The species is named in honour of Dr. Valery A. Korneyev, Dr. Elena Kameneva and Severin Korneyev, Ukrainian dipterologists, in recognition of their invaluable contribution into study of Palaearctic Tephritoidea.
