Amauromyza (Amauromyza) carlinae (Hering)

( Figs. 45–48 , 349–354 )

Material examined: Ukraine: Poltava Region: near Luchky , 48°57’N, 34°09’E, 14.vii.2016, Yu. Guglya, ex Echinops sphaerocephalus (1♂) . Kharkiv Region: near Petrivske , 49°10’N, 36°58’E, 14–15.vii.2020, Yu. Guglya, ex Echinops sphaerocephalus (2♂ 3♀) .

Hosts. Asteraceae : Carlina L., Cirsium Mill. ( Benavent-Corai et al. 2005) . Echinops sphaerocephalus L.—a newly recorded host plant.

Mine. ( Fig. 45 ) Several (up to eight) larvae together form one large whitish-brown blotch mine. Pupation takes place outside the mine.

Puparium. ( Figs. 46–48 ) Reddish-brown, glossy, 2.5 mm long, with deep segmentation; surface quite smooth except for wide black spine bands. Posterior spiracles set on stout conical protuberances entirely strongly separate; orange, with five hook-like bulbs set in a circular configuration: three (smaller) located dorsally and two (larger) ventrally. Anal plate distinctly protruding above the surface of the puparium viewed from the side and directed ventrally.

Cephalopharyngeal skeleton. ( Fig. 349 ) Right mouthhook much larger than the left, both with ventro-anterior portion distinctly abducted. The right mouthhook bears two sharp accessory teeth and the left hook bears one tooth. Parastomal bar short, curved dorso-anteriorly. Intermediate sclerite wide and short, 0.8× as long as maximum height of left mouthhook. The mouthhook, intermediate sclerite and dorso-anterior portion of the pharyngeal sclerite are strongly sclerotized, posterior half of the dorsal cornu and the ventral cornu much less so. The ventral cornu bears a small “closed” window. Indentation index 83.

Female head. ( Figs. 350, 351 ) Brown, with antenna and face black; orbit not projecting above eye in profile; 2 orb s, 4 fr s; lunule low, narrow reaching the level of the anterior fr s; pped small, rounded; gena medially 0.15× as high as maximum height of eye.

Female genitalia. ( Figs. 352–354 ) Capsule of spermatheca relatively small, 0.15× as high as height of anterior part of oviscape. Proctiger relatively wide, 2.62× as long as maximum width; cylindrical in posterior half narrowing dramatically and bearing an X-shaped well sclerotized appendage anteriorly. Surface of the posterior half covered with numerous fine spines. Posterior margin of proctiger flattened; cercus relatively wide and acute apically. Spermathecae unequal in size, dark brown, torus-shaped, without basal collar. Capsule of spermatheca 0.47× as high as maximum width. Spermathecal duct weakly sclerotized.

Distribution. Spain, France, Germany, Poland, Slovakia ( Papp & Černý 2016). Ukraine (first record).
