Phytomyza glechomae Kaltenbach (Figs. 194–196, 567–571) Material examined: Ukraine: Kyiv Region: near Obukhiv, Tarasivka, 50°09’N, 30°35’E, 23.v.2019 —pupariation, Yu. Guglya, ex Glechoma hederacea — 7.ix.2019 (1♀); Kharkiv Region: near Rubizhne, 50°07’N, 36°46’E, 19.v.2019 —pupariation, Yu. Guglya, ex Glechoma hederacea (1 puparium); near Petrivske, 49°10’N, 36°58’E, 2.v.2020 —mines with larvae, Yu. Guglya, ex Glechoma hederacea —2.ix, 13.ix and 5.x.2020 (3♀). Host. Lamiaceae: Glechoma hederacea L. (Spencer 1976). Mine. (Fig. 194) The larva forms an irregular linear upper surface mine. The width of the mine greatly increases during the course of the larval life. Sometimes the loops of the mine are laid so closely that it appears as a blotch. Pupation takes place outside the mine in the soil. Puparium. (Figs. 195, 196) Brown, semi-glossy, 2.5 mm long, with distinct segmentation; surface quite smooth except for wide bands of fine spines and the last two abdominal segments finely wrinkled. Posterior spiracles set on wide and short conical protuberances that are entirely separate; black, glossy and sickle-shaped. Anal plate strongly protruding above the surface of the puparium viewed from the side and directed ventro-posteriorly. Cephalopharyngeal skeleton. (Fig. 567) Right mouthhook slightly larger than the left, each with distinct abducted portion directed ventrally and bearing two accessory teeth. Intermediate sclerite long and slightly curved, 1.28× as long as maximum height of left mouthhook. The mouthhook, most of the intermediate sclerite, and the dorsal cornu medially and anteriorly are strongly sclerotized; the intermediate sclerite dorsally and the rest of the pharyngeal sclerite are much less so. The ventral cornu bears a small and very narrow “closed” window in the posterior half. Indentation index 83. Female head. (Figs. 568, 569) Brown, with antenna and postgena black; orbit slightly projecting above eye in profile; 2 orb s, 1 fr s; lunule narrow, higher than a semicircle, reaching the level of the anterior orb s; pped large, rounded; gena medially 0.46× as high as maximum height of eye. Female genitalia. (Figs. 570, 571) Capsule of spermatheca relatively small, 0.19× as high as height of anterior part of oviscape. Spermathecae equal in size, dark brown, flattened basally and apically, wider than high. Internal duct invagination cylindrical, narrowing medially, as deep as height of spermatheca. Spermathecal duct weakly sclerotized. Ventral receptacle S-shaped, with weakly sclerotized tail that is two-bladed in basal half. Body of receptacle spherical with sharply curved basal connecting tube, strongly sclerotized, 0.57× as wide as width of capsule of spermatheca; with opening 0.5× as wide as diameter of spherical part of body. Distribution. Palaearctic, recorded from 18 European countries and also Japan (Papp & Černý 2019).
