Liriomyza congesta (Becker)

( Figs. 147–149 , 481–486 )

Material examined: Ukraine: Vinnytsa Region: near Kurenivka , 48°15’N, 29°11’E, 9.v.2019, Yu. Guglya (1♂) ; Kharkiv Region: Sokolnyky, Kharkiv , 49°25’N, 36°15’E, 3.viii.2011, Yu. Guglya, ex Trifolium sp. (3♂ 4♀) ; Sumy Region: Trostyanets , 50°28’N, 34°55’E, 7.v.2013, Yu. Guglya (1♂) .

Hosts. Fabaceae : 26 genera of host plants ( Benavent-Corai et al. 2005), additionaly Warrington (2021) noted Galega Tourn. ex L., Ononis L. and Solanaceae : Capsicum L.

Mine. The larva forms a linear leaf mine. Pupation takes place outside the mine, often attached to the leaf surface.

Puparium. ( Figs. 147–149 ) Yellow, translucent, glossy, 1.5 mm long, with distinct segmentation; surface quite smooth except for narrow spine bands. Posterior spiracles set on wide and short conical protuberances that are entirely separate; brown, with three sharp sessile bulbs set in a circular configuration.Anal plate brown, not protruding above the surface of the puparium viewed from the side and directed ventrally.

Cephalopharyngeal skeleton. ( Fig. 481 ) Right mouthhook much larger than the left, each bearing two accessory teeth. Intermediate sclerite long and narrow, 0.96× as long as maximum height of left mouthhook. The mouthhook is strongly sclerotized, intermediate and pharyngeal sclerites much less so. Indentation index 89.

Female head. ( Figs. 482, 483 ) Dark yellow, with only arista, oc tr and postgena behind vertical setae black; orbit not projecting above eye in profile; 1 orb s, 2 fr s; lunule low, narrow, semicircular, reaching the level of the anterior fr s; pped large, rounded; gena medially 0.28× as high as maximum height of eye.

Thorax viewed from the side. ( Fig. 484 ) Mostly dark yellow, with kepst in ventral two-thirds, mr ventroposteriorly and anatg posteriorly black; pprn dorsally, anepist ventrally, anepm medially and mtkepst posteriorly bear elongated blackish spots. Calypter and fringe yellowish-grey, margin black. Cx 1 and cx 3 blackish-yellow proximally.

Female genitalia. ( Figs. 485, 486 ) Capsule of spermatheca relatively small, 0.2× as high as height of anterior part of oviscape. Spermathecae equal in size, dark brown, spherical, sometimes invaginated subapically. Spermathecal duct weakly sclerotized.

Distribution. This species is very common throughout most of Europe ( Papp & Černý 2017). Ukraine (first record).
