description: Cerodontha (Dizygomyza) iraeos (Robineau-Desvoidy)   
(Figs. 89–93, 412–415)  
 Material examined: Ukraine: Transcarpathia: near Chop, flood land on the River Latoritsa Bank, 48°27’N, 22°12’E, 18.ix.2016 —mine with exuvium collected, Yu. Guglya, ex Iris pseudacorus (1 exuvium); Vinnytsa Region: Chechelnyk, 48°12’N, 29°20’E, 5.vii.2019, Yu. Guglya, ex Iris pseudacorus (2♂ 4♀); Donetsk Region: Kryva Luka, 13 km SEE Lyman, 48°52’N, 37°54’E, 7–12.vi.2019, Yu. Guglya, ex Iris pseudacorus (5♂ 3♀).   
 Hosts. Iridaceae: Iris pseudacorus L. (Spencer 1976), I. cristata Aiton (Eiseman & Lonsdale 2018), Gladiolus Tourn. ex L. and Typhaceae: Typha L. (Warrington 2021).   
 Mine. (Figs. 89) The larva forms a white linear mine on the upper side of the leaf. Frass normally appearing as a single black spot several (2–5) centimetres from puparium. Pupation takes place within the mine (Fig. 90).   
 Puparium. (Figs. 91–93) Orange viewed from above, reddish-brown viewed from the side and black viewed from below, glossy, 2.7 mm long, with weak segmentation; surface wrinkled except for wide spine bands. Both posterior spiracles orange, tube-shaped, set on a single wide trapezoidal protuberance in posterior view. Posterior spiracles viewed from the side are depicted in Nowakowski (1973: Fig. 260). Anal plate slightly protruding above the surface of the puparium viewed from the side and directed posteriorly.   
 Cephalopharyngeal skeleton. (Fig. 412) Right mouthhook larger than the left, both with long finger-like abducted portion directed ventro-posteriorly. Each mouthhook bears two apically rounded accessory teeth. Intermediate sclerite long, narrow and waved, 1.33× as long as maximum height of the left mouthhook. The mouthhook and intermediate sclerite are strongly sclerotized, the pharyngeal sclerite much less so. Indentation index 84. See also in Nowakowski (1973: Fig. 218), Sasakawa (1961: Fig. 56 l).   
 Female head. (Figs. 413, 414) Yellowish-black, with antenna, palpus, oc tr and postgena black, proboscis yellow; orbit not projecting above eye in profile, 2 orb s, 2 fr s; lunule semicircular, reaching the level between fr s; pped large, flattened ventro-anteriorly; gena medially 0.15× as high as maximum height of eye.   
 Female genitalia. (Fig. 415) Spermathecae equal in size, brown, concave apically, mushroom-shaped, 0.3× as high as maximum width. Neck of spermatheca conical, wider than long, narrowed in the direction of duct, 0.35× as long as maximum width. Spermathecal duct wide, crested, weakly sclerotized. Proctiger see in Sasakawa (1961: Fig. 56 h).   
 Distribution. Widespread in Europe, Japan and South Korea (Papp & Černý 2016); tentatively recorded from USA (Eiseman & Lonsdale 2018). Ukraine (first record).
