Mine. Several larvae form a blotch mine on the upper side of the leaf. ( Eiseman & Lonsdale 2018)

Puparium. ( Figs. 94–96 ) Black, mirror-shining except two last abdominal segments, which are matt and finely folded; 3.0 mm long, with deep segmentation; surface smooth except for narrow wrinkled spine bands. Both posterior spiracles are set on a single wide conical glossy protuberant mounting; black, glossy, each with three short, curved and finger-like bulbs. Posterior spiracles viewed from the side and the puparium are depicted in Nowakowski (1973: Figs. 195 , 233 ). Anal plate strongly protruding above the surface of the puparium viewed from the side and directed posteriorly.

Cephalopharyngeal skeleton. ( Fig. 416 ) Right mouthhook larger than the left, both rather wide, rounded ventrally. Each mouthhook bears two sharp accessory teeth. Intermediate sclerite narrow, curved, with ventral invagination posteriorly, 1.42× as long as maximum height of the left mouthhook. The mouthhook, intermediate sclerite and anterior portion of the pharyngeal sclerite are strongly sclerotized, dorsal and ventral cornua much less so. Indentation index 83. See also in Nowakowski (1973: Fig. 195 ).

Female head. ( Figs. 417, 418 ) Yellowish-brown, with antenna, frons, postgena and palpus black, proboscis yellow; orbit not projecting above eye in profile, 2 orb s, 2 fr s; lunule very high, narrowing posteriorly, reaching the level between orb s; pped small, rounded; gena medially 0.19× as high as maximum height of eye.

Female genitalia. ( Figs. 419, 420 ) Capsule of spermatheca relatively small, 0.16× as high as height of anterior part of oviscape. Spermathecae equal in size, dark brown, semicircular, but slightly asymmetrical, being flattened basally. Neck of the spermatheca long, curved, as strongly sclerotized as capsule of spermatheca, and as long as the height of the spermatheca. Spermathecal duct weakly sclerotized.

Distribution. Holarctic ( Papp & Černý 2016). Ukraine (first record).
