Hosts. Lamiaceae : Leonurus L. ( Benavent-Corai et al. 2005), Lamium album L. ( Papp & Černý 2016). Betonica officinalis L., Phlomoides tuberosa (L.) Moench and Ballota nigra L. — newly recorded host plants.

Mine. ( Fig. 58 ) The solitary larva forms a beige irregular upper surface linear-blotch mine. Pupation takes place outside the mine.

Puparium. ( Figs. 59–61 ) Brown, glossy, 3.2 mm long, with deep segmentation; surface quite smooth except for narrow black spine bands and two last abdominal segments are wrinkled. Posterior spiracles set on stout conical protuberances entirely widely separate; with three hook-like sessile bulbs set in a circular configuration. Anal plate distinctly protruding above the surface of the puparium viewed from the side and directed ventrally.

Cephalopharyngeal skeleton. ( Fig. 363 ) Right mouthhook larger than the left, both flattened ventrally. Each mouthhook bears two sharp accessory teeth. Intermediate sclerite narrow and short, 0.79× as long as maximum height of left mouthhook. The mouthhook, intermediate sclerite and dorso-anterior portion of the pharyngeal sclerite are strongly sclerotized, posterior portion of the dorsal cornu and the ventral cornu much less so. Indentation index 83.

Female head. ( Figs. 364, 365 ) Brownish-black, with orbit not projecting above eye in profile, 2 orb s, 3 fr s and low and flattened posteriorly lunule, reaching the level of the anterior fr s; pped small, flattened anteriorly; gena medially 0.15× as high as maximum height of eye.

Female genitalia. ( Figs. 367, 368 ) Proctiger relatively wide, 2.64× as long as maximum width; uniformly narrowing and bearing two straight, elongated and well sclerotized appendages anteriorly. Surface of the posterior half covered with numerous fine spines. Posterior margin of proctiger strongly concave medially, with rounded convex portions laterally; cercus relatively wide and rounded apically. Spermathecae equal in size, dark brown, hemispherical, flattened apically, without basal collar. Capsule of spermatheca 0.53× as high as maximum width. Internal duct invagination 0.36× as wide as width of spermatheca. Spermathecal duct corrugated and weakly sclerotized.

Distribution. A rare European species: the Czech Republic, Germany, Lithuania, Poland, Switzerland ( Papp & Černý 2016). Ukraine (first record).
