Running it though the Nartshuk's key (2016) you would end up at P. ruficornis, but her illustrations of the genitalia are not particularly detailed and neither the posterior view nor the ventral view show the clear tooth on each of the gonostyli, though the posterior view she gives may hint at an apical narrowing. Checking Ismay's thesis, both the posterior and ventral views of the genitalia show the apicalnarrowing, but he also illustrated a gonostylus at maximum width (possible at 45 degree angle between posterior and ventral views) and that seems a good match with your last illustration. So, yes, this is P. ruficornis.

Chloropidae, Oscinellinae, Lasiambia sp. The very fine parallel stripes on the frons (called "fettglänzend" by Duda in Lindner (1932-3)), the gena being obliquely divided in an upper and well separated dark lower part, labellum relatively long, nearly parallel postverticals (= postocellars), large palpi and in some species a rugose scutum let identify this genus. The central pair of pseudotracheae of the labellum partly is elongated and pointing backwards, its function is unknown. This species belongs to this group with the abundant species L. palposa (Fallén, 1820). Lasiambia species develop in grasshopper eggs, mantid oothecae, cells of solitary bees, ulcerous sap flows of trees and other peculiar substrates. Several species in central and mediterranean Europe and in the Near East are still undescribed.
