Melanagromyza angeliciphaga Spencer

( Figs. 26–28 , 321–325 )

Material examined: Ukraine: Kharkiv Region: Tymchenky , 49°44’N, 36°08’E, 26–29.v.2017, March 2019, Yu. Guglya, ex Angelica sylvestris (8♂ 6♀) .

Hosts. Apiaceae : Angelica sylvestris L., A. archangelica L., Heracleum sphondylium L., Pastinaca sativa L. ( Papp & Černý, 2015).

Mine. The larva forms an internal stem mine. Pupation takes place in the basal part of the stem.

Puparium. ( Figs. 26–28 ) Straw-coloured, silky shining, 4.0 mm long, with not visible segmentation; surface quite smooth. Posterior spiracles set flat on the body cuticle, entirely separate; black, shining, oval, with median spine curved dorsally. Thirteen linear bulbs surround the median spine. Anal plate not protruding above the surface of the puparium viewed from the side and directed ventrally.

Female head. ( Figs. 321, 322 ) Brownish-black, with orbit distinctly projecting above eye in profile, 2 orb s, 3 fr s and high broad rounded lunule reaching the level of the posterior fr s; gena in widest part 0.23× as high as maximum height of eye.

Female genitalia. ( Figs. 323–325 ) Blade of egg guide relatively narrow, 12× as long as maximum width, acute apically, with medial membrane without any scales. Outer marginal denticles fine, scarcely visible. Proctiger very narrow, 13× as long as maximum width. Egg guide 1.15× as long as proctiger. Spermathecae unequal in size, dark brown, oval and flattened basally; internal duct invagination 0.5× as deep as height of spermatheca. Basal collar consists of several lobes: in larger spermatheca lobes narrow, elongated and swirling around the spermathecal duct whilst in smaller spermatheca they are wide and short. Spermathecal duct very weakly sclerotized.

Distribution. Belgium, British Isles, the Czech Republic, Denmark, Estonia, France, Hungary, Germany, Greece, Lithuania, the Netherlands, Poland, Slovakia, Spain, Sweden ( Papp & Černý 2015). Ukraine (first record).
