Phytoliriomyza melampyga (Loew) View in CoL

( Figs. 284–286 View FIGURES 278–286 , 542–544 View FIGURES 537–544 )

Material examined: Ukraine: Transcarpathia: “Skalka”, near Uzhhorod , 48°41’N, 22°24’E, 20.ix.2016, Yu. Guglya, ex Impatiens noli-tangere (1♂ 1♀) GoogleMaps ; Volyn Region: Dachne, near Lutsk , 50°48’N, 25°22’E, 9–10.vi.2019, Yu. Guglya, ex Impatiens parviflora (1♀) GoogleMaps .

Hosts. Balsaminaceae : Impatiens noli-tangere L., I. parviflora DC. ( Papp & Černý 2017) . I. capensis Meerb. , I. granulifera H. Perrier , I. scabrida DC. ( Ellis 2001 –2021).

Mine. ( Fig. 284 View FIGURES 278–286 ) The solitary larva forms an irregular white upper surface linear-blotch mine. Pupation takes place outside the mine in the soil.

Puparium. ( Figs. 285, 286 View FIGURES 278–286 ) Dark orange, semi-glossy, 2.6 mm long, with distinct segmentation; surface quite smooth except for one-row spine bands. Posterior spiracles set on scarcely visible conical protuberances that are entirely separate; brown, with one large hook-like sessile bulb directed ventrally and 2 small rounded bulbs directed dorsally. Anal plate brown, slightly protruding above the surface of the puparium viewed from the side and directed ventro-posteriorly.

Cephalopharyngeal skeleton. ( Fig. 542 View FIGURES 537–544 ) Right mouthhook much larger than the left, each bearing two long and sharp accessory teeth. Left hook with ventral portion sharply abducted. Intermediate sclerite massive, slightly curved dorsally, equal in size to the maximum height of the left mouthhook. The mouthhook and the intermediate sclerite centrally are strongly sclerotized, the intermediate sclerite dorso-anteriorly and ventro-posteriorly and the pharyngeal sclerite much less so. The ventral cornu bears a narrow “closed” window in the posterior half. Indentation index 90.

Female genitalia. ( Figs. 543, 544 View FIGURES 537–544 ) Capsule of spermatheca relatively small, 0.21× as high as height of anterior part of oviscape. Spermathecae unequal in size, dark brown, obovate, flattened basally, with shallow internal duct invagination. Largest spermatheca 1.25× as high as the smallest one. Neck of spermatheca distinctly narrower than spermathecal base. Spermathecal duct weakly sclerotized.

Distribution. Widespread Holarctic species ( Papp & Černý 2017). Ukraine (first record).

Comments. In Ukraine reared material is known only from two localities, but this species seems to be common based on the presence of numerous mines on Impatiens parviflora and I. noli-tangere in many regions. Besides Transcarpathia and the Volyn Region, empty mines were found in the Vinnytsa, Khmelnytsk, Chernyhiv, Kyiv, Kharkiv, Poltava and Sumy Regions.
