Hosts. Campanulaceae : Adenophora Fisch. , Campanula L., Legousia Durande , Phyteuma L. ( Benavent-Corai et al. 2005).

Mine. ( Fig. 30 View FIGURES 25–32 ) The solitary larva forms a greenish-white upper surface blotch mine, which eventually becomes brown. Pupation takes place outside the mine.

Puparium. ( Figs. 31, 32 View FIGURES 25–32 ) Bright yellow, glossy, 2.0 mm long, with deep segmentation; surface quite smooth. Posterior spiracles brown, set on yellow conical protuberances that are strongly separated; with four hook-like sessile bulbs set in a circular configuration. Anal plate not protruding above the surface of the puparium viewed from the side; directed ventrally. Two sharp conical ventral tubercles developed on each side of the anal plate viewed from the side and posteriorly.

Cephalopharingeal skeleton. ( Fig. 165 View FIGURES 162–168 ) Right mouthhook larger dorsally than the left, both with ventro-anterior portion acute and abducted ventrally. Right mouthhook bears two accessory teeth, left bears one; all teeth are large, sharp, uniformly curved ventrally. Mouthhooks strongly sclerotized, intermediate sclerite and dorsal and ventral cornua much less so. Intermediate sclerite straight and wide. Dorsal cornu gradually curved and narrowed. Ventral cornu very weakly sclerotized; bearing a “closed” window posteriorly. Indentation index 84.

Female head. ( Figs. 162, 163 View FIGURES 162–168 ) Black, with fronto-orbital plate slightly visible laterally; 3 ors, 2 ori; 1 st fl small, oval. Gena wider at rear, at widest part 0.24× as wide as maximum height of eye.

Wing. ( Fig. 164 View FIGURES 162–168 ) Greyish; with dark grey veins. Costal veins ending afrer M 1; last section of CuA 1 3.5× as long as penultimate; first cross-vein at midpoint of discal cell; calypter and fringe grey, margin black. Wing length 1.6.mm.

Female genitalia. ( Figs. 166–168 View FIGURES 162–168 ) Spermathecae of medium size, 0.35× as wide as height of anterior part of oviscape. Proctiger short, generally cylindrical, tapered in the middle. Several long setae located separately along posterior margin. Cercus oval, flattened apically and basally, 0.55× as long as proctiger; patches of long setae located laterally and brush of strong short setae located apically. Spermathecae equal in size, brown, wider than high and flattened basally. Internal duct invagination wide, oval 0.73× as deep as height of spermatheca. Spermathecal duct is weakly sclerotized but distinctly wrinkled.

Distribution. Widely distributed European species ( Papp & Černý 2016). Ukraine (first record).
