Host. Cannabaceae : Humulus lupulus L. ( Spencer 1976).

Puparium. ( Figs. 13–15 ) Brown, glossy, 3.0 mm long, with deep segmentation; surface quite smooth except for spine bands. Posterior spiracles of the same colour as the rest of the puparium, shining and set on a stout conical protuberance, that are entirely separate; brown, with three or four strong slits set in a circular configuration at acute angles to each other. Anal plate black, not protruding above the surface of the puparium viewed from the side and directed ventro-posteriorly.

Cephalopharyngeal skeleton. ( Fig. 299 ) Both mouthhooks equal in size and shape, with finger-like abducted portion directed ventro-anteriorly and rounded ventro-posteriorly. Each mouthhook bears two wide, long and blunt accessory teeth. Intermediate sclerite short and wide, 0.89× as long as height of mouthhook. Parastomal bar exist, slightly curved dorso-anteriorly. Dorsal and ventral cornua bear wide and long “closed” windows. The pharyngeal sclerite is much more sclerotized dorso-anteriorly. Indentation index 88.

Female genitalia. Discussed in Guglya (2017).

Distribution. Widespread but rare European species ( Papp & Černý 2015). Widespread in Ukraine: from Trans- carpathia and Volyn to Kharkiv and Dnipropetrovsk Regions ( Guglya 2017, 2020).
