Chromatomyia periclymeni de Meijere

( Figs. 127–129 , 460–464 )

Material examined: Ukraine: Donetsk Region: Donetsk, Botanical Garden , 47°59’N, 37°52’E, 20.ix.2015 —numerous mines with larva collected, 20.ii.2016, A. Gubin, ex Lonicera sp. (2♂ 3♀) .

Hosts. Caprifoliaceae : Lonicera L., Symphoricarpos Duhamel ( Benavent-Corai et al, 2005), Leycesteria Wall. ( Warrington 2021) .

Mine. ( Fig. 127 ) The solitary larva forms a brown star mine, usually in the leaf centre. Pupation takes place within the mine.

Puparium. ( Figs. 128, 129 ) Straw-coloured, translucent, 2.0 mm long, with distinct segmentation; surface quite smooth except for narrow bands of minute spines. Posterior spiracles set on stout conical protuberances and entirely separate; brown, with 20 sessile bulbs set in a kidney-like configuration. Anal plate distinctly protruding above the surface of the puparium viewed from the side and directed posteriorly.

Cephalopharyngeal skeleton. ( Fig. 460 ) Right mouthhook larger than the left, each with sharp abducted portion directed ventrally and bearing two blunt accessory teeth. Intermediate sclerite long, narrow and straight, 1.4× as long as maximum height of left mouthhook. The mouthhook, the intermediate sclerite and the dorsal cornu centrally are strongly sclerotized and the rest of the pharyngeal sclerite is much less so. The ventral cornu bears a narrow “closed” window located centrally. Indentation index 80.

Female head. ( Figs. 461, 462 ) Ash grey with gena and proboscis yellowish; orbit projecting above eye in profile; 2 orb s, 2 fr s; lunule broad and high with tapered margin dorsally, reaching the level of the posterior fr s; pped large, rounded; gena medially 0.3× as high as maximum height of eye.

Female genitalia. ( Figs. 463, 464 ) Capsule of spermatheca relatively very small, 0.06× as high as height of anterior part of oviscape. Spermathecae equal in size, dark brown, spherical. Spermathecal duct weakly sclerotized. Ventral receptacle compressed S-shaped, with weakly sclerotized tail that widens basally. Body of receptacle oval with sharply curved long basal connecting tube, strongly sclerotized, 2.9× as wide as capsule of spermatheca; with opening located on distinct narrowing projection, 0.6× as wide as diameter of spherical part of body.

Distribution. Occurs in 21 European countries ( Papp & Černý 2019), Belarus ( Volosach 2019). Ukraine (first record).
