Cerodontha (Cerodontha) phragmitophila Hering

( Figs. 75–77 , 388–392 )

Material examined: Ukraine: Kharkiv Region: near Petrivske , 49°10’N, 36°58’E, 27, 30.vi.2019, Yu. Guglya, ex Phragmites australis (2♀) .

Hosts. Poaceae : Arundo donax L., Phragmites australis (Cav.) Trin ex Steud. ( Papp & Černý 2016) .

Mine. Two larvae feed together in one blotch mine. Pupation takes place within the mine.

Puparium. ( Figs. 75–77 ) Yellowish-orange, glossy, 3.2 mm long, with weak segmentation. The surface of all segments except the last two is quite smooth except for narrow spine bands; last two segments wrinkled. Posterior spiracles set on stout protuberances that are entirely separate; brown, fan-shaped, with up to twenty sessile bulbs arranged in irregular group. Anal plate slightly protruding above the surface of the puparium viewed from the side and directed ventro-posteriorly.

Cephalopharyngeal skeleton. ( Fig. 388 ) Right mouthhook larger than the left, both with sharp abducted portion directed ventrally. Each mouthhook bears two accessory teeth. Intermediate sclerite long, narrow, 1.75× as long as height of left mouthhook. The mouthhook, intermediate sclerite and anterior portion of the pharyngeal sclerite are strongly sclerotized, dorsal and ventral cornua are much less so. Indentation index 77. See also in Nowakowski (1956: Fig. 183 ).

Female head. ( Figs. 389, 390 ) Yellow, with only oc tr, pped and arista black; pped with finger-like abducted anterodorsal process; 2 orb s, 1 fr s, lunule lunule narrow, higher than a semicircle, reaching the level between fr s and the anterior orb s.

Female thorax. ( Fig. 391 ) Bicolor, yellow and black: presutular area of sct almost black, postsutular area black only laterally, area between dc s yellow. Sctl black laterally, with ds sctl s on black ground and ap sct s on yellow ground.

Female genitalia. ( Fig. 392 ) Spermathecae equal in size, brown, spherical and flattened basally, with narrow rim-shaped basal collar.

Distribution. Belgium, British Isles, Bulgaria, Croatia, the Czech Republic, France including Corsica, Greece, Hungary, Italy, Poland, Spain including Canary Islands, former Yugoslavia, also recoded from Cyprus, Egypt, Israel, Kazakhstan, Pakistan, Uzbekistan ( Papp & Černý 2016). Ukraine (first record).
