( Figs. 100–103 View FIGURES 94–103 , 425–430 View FIGURES 421–430 )

Material examined: Ukraine: Transcarpathia: 4 km SW Rakhiv , 48º01’N, 24º10’E, 20.vii.2017, Yu. Guglya (1♂) GoogleMaps ; Kharkiv Region: near Petrivske , 49°10’N, 36°58’E, 8–9.vii.2020, Yu. Guglya, ex Calamagrostis canescens (2♂ 5♀) GoogleMaps ; near Rubizhne , 50°10’N, 36°47’E, 23–30.vii.2020, Yu. Guglya, ex Dactylis glomerata (3♂ 6♀) GoogleMaps ; near Haidary, The National Nature Park “Homilshanski Lisy”, 49°37’N, 36°19’E, 29.vii–3.viii.2020, Yu.

Hosts. Poaceae : Calamagrostis arundinacea (L.) Rpth., Poa chaixii Vill. Melica uniflora Retz., M. nutans L., Molinia caerulea (L.) Moench (Nowakowski 1972). Calamagrostis canescens (Weber) Roth and Dactylis glomerata L. are newly recordered host plants.

Mine. ( Fig. 100 View FIGURES 94–103 ) The larva forms a white upper surface blotch mine. The larva may be solitary or several larvae (up to 10) may form a single mine. Pupation takes place within the mine.

Puparium. ( Figs. 101–103 View FIGURES 94–103 ) Black, mirror-shining except two last abdominal segments, which are matt and finely folded; 2.5 mm long, with deep segmentation; surface smooth except for narrow wrinkled spine bands. Both posterior spiracles set on a single wide conical finely folded protuberance; brown, glossy, each with three short, curved and finger-like bulbs. Posterior spiracles viewed from above and anterior and posterior spiracular bulbs viewed from the side are depicted in Nowakowski (1973: Figs. 196 View FIGURES 194–201 , 237 View FIGURES 236–244 ). Anal plate strongly protruding above the surface of the puparium viewed from the side and directed posteriorly.

Cephalopharyngeal skeleton. ( Fig. 425 View FIGURES 421–430 ) Right mouthhook larger than the left, both flattened ventrally. Each mouthhook bears two sharp accessory teeth. Intermediate sclerite narrow, straight, with ventral invagination posteriorly, 1.37× as long as maximum height of left mouthhook. The mouthhook, intermediate sclerite and anterior portion of the pharyngeal sclerite are strongly sclerotized, dorsal and ventral cornua in contrast very weakly so. Indentation index 90.

Female head. ( Figs. 426, 427 View FIGURES 421–430 ) Black, with yellowish-orange proboscis; orbit not projecting above eye in profile, 2 orb s, 2 fr s; lunule very high and dramatically narrow, reaching the level of the anterior orb s; pped of medium size, flattened ventro-anteriorly; gena medially 0.12× as high as maximum height of eye.

Female genitalia. ( Figs. 428–430 View FIGURES 421–430 ) Capsule of spermatheca relatively small, 0.18× as high as height of anterior part of oviscape. Proctiger relatively narrow, 4× as long as maximum width. Spermathecae equal in size, dark brown, spherical, flattened basally, with narrow rim-shaped basal collar. Neck of spermatheca conical, slightly longer than wide, narrowed in the direction of duct, 1.06× as long as maximum width. Spermathecal duct is weakly sclerotized.

Distribution. The Czech Republic, Germany, Ireland, Poland, Slovakia ( Papp & Černý 2016). Ukraine (first record).
