Described by Pakalniškis from Lithuania. Pakalniškis assumes that the records of Ph. sitchensis from Germany and Britain by Spencer (1990a) in fact refer to Ph. virosae.

notes

This species was described from Lithuania by Pakalniškis (2000a). The only text he spends on the mine and the puparium is that they are exactly similar to those of Ph. sitchensis Griffiths (1973b), a species from arctic Canada, living on Conioselinum chinense; nothing is said about the larva by Pakalniškis. The description of the mine and the puparium by Griffith run as follows “Mine entirely linear, mainly following sinuations of leaflet margins, about 5 cm long, 1-1.5 mm wide terminally; faeces deposited as fine particles, mostly close together or forming beaded strips; mine entirely on upper surface of leaf, appearing whitish green in reflected light; larvae leavin leaf through semicircular slit on upper surface before puparium formation. Puparia shining black, about 1.7 mm long, smoothly rounded with intersegmental boundaries scarcely impressed; anal lobes absent.”.
