description: Liriomyza tragopogonis de Meijere   
(Figs. 163–167, 519–524)  
 Material examined. Ukraine: Kharkiv Region: near Petrivske, 49°10’N, 36°58’E, 10–12.vii.2020, Yu. Guglya, ex Tragopogon podolicus (5♂ 10♀); Donetsk Region: Kryva Luka, 13 km SEE Lyman, 48°52’N, 37°54’E, 11–14.vi.2019, Yu. Guglya, ex Tragopogon sp. (1♂ 2♀).   
 Hosts: Asteraceae: Tragopogon porrifolius L. and T. pratensis L. (Spencer 1990). Tragopogon podolicus (DC) Nikitina – a newly recorded host plant.   
 Mine: (Fig. 163) The mine begins as a channel in the leaf midrib and ends up as a channel in the pith of the stem. Pupation takes place inside the stem (Fig. 164). After pupation the mine in the leaf turns brown (as in Fig. 163).   
 Puparium. (Figs. 165–167) Straw-coloured, translucent, glossy, 1.9 mm long, with distinct segmentation; surface quite smooth except for narrow spine bands. Posterior spiracles set on wide and short conical protuberances that are entirely separate; brown, with numerous minute sessile bulbs set in a circular configuration. Anal plate brown, scarcely protruding above the surface of the puparium viewed from the side and directed ventrally.   
 Cephalopharyngeal skeleton. (Fig. 519) Right mouthhook larger than the left, each with ventral portion sharply abducted and bearing two accessory teeth. Intermediate sclerite short, curved dorsally, 0.66× as long as maximum height of left mouthhook. The mouthhook, the intermediate sclerite and the pharyngeal sclerite anteriorly are strongly sclerotized, dorsal and ventral cornua much less so. The ventral cornu bears an elongated “closed” window posteriorly. Indentation index 83.   
 Female head. (Figs. 520, 521) Dark yellow to yellow, with only arista and back head (ocp and m ocp scl) black; orbit slightly projecting above eye in profile; 2 orb s, 2 fr s; lunule of medium height, semicircular, reaching the level of the anterior fr s; pped of medium size, rounded; gena medially 0.36× as high as maximum height of eye.   
 Thorax viewed from the side. (Fig. 522) Mostly bright yellow, with kepst in ventral two-thirds and anatg black; anepist ventrally and anepm medially bear small elongated blackish spots. Calypter and fringe yellow, margin black.   
 Female genitalia. (Figs. 523, 524) Capsule of spermatheca relatively small, 0.19× as high as the length of the anterior part of the oviscape. Spermathecae equal in size, dark brown, obovate, with narrow rim-shaped basal collar. Spermathecal duct weakly sclerotized except narrow zone near base of the spermatheca.   
 Distribution: British Isles, the Czech Republic, Estonia, France, Germany, Hungary, Latvia, Lithuania, Poland and Sweden (Papp & Černý 2017). Ukraine (first record).
