Amauromyza (Amauromyza) chamaebalani (Hering)

( Figs. 49–52 , 355–358 )

Material examined: Ukraine: Kharkiv Region: Piatуkhatky, N Kharkiv, 50°05’N, 36°14’E, 27.vi.2013, Yu. Gug- lya, ex Lathyrus sp. (1♂ 1♀) .

Hosts. Fabaceae : Lathyrus L., Pisum L. ( Benavent-Corai et al. 2005).

Mine. ( Fig. 49 ) The solitary larva forms a white upper surface blotch mine. Pupation takes place outside the mine.

Puparium. ( Figs. 50–52 ) Yellow, translucent, glossy, 1.6 mm long, with distinct segmentation; surface quite smooth except for narrow spine bands. Posterior spiracles set on short conical protuberances that are entirely separate; brown, with six sessile bulbs set in a circular configuration. Anal plate brown, protruding above the surface of the puparium viewed from the side and directed ventro-posteriorly.

Cephalopharyngeal skeleton. ( Fig. 355 ) Right mouthhook larger than the left, both with ventral rounded abducted portion directed anteriorly. Each mouthhook bears two sharp accessory teeth. Intermediate sclerite wide and short, 1.32× as long as maximum height of left mouthhook. Intermediate and pharyngeal sclerites are much less sclerotized than the mouthhook. Indentation index 91.

Female head. ( Figs. 356, 357 ) Brown, with orbit distinctly projecting above eye in profile, 2 orb s, 2 fr s and very low lunule, not reaching the level of the anterior fr s; pped of medium size, flattened ventrally; gena medially 0.3× as high as maximum height of eye.

Female genitalia. ( Fig. 358 ) Spermathecae equal in size, dark brown, hemispherical, flattened basally, without basal collar. Internal duct invagination deep and wide, dramatically narrowing apically, up to 0.7× as deep as height of spermatheca. Spermathecal duct weakly sclerotized.

Distribution. France, Germany, Hungary, Lithuania ( Papp & Černý 2016). Ukraine (first record).
