Remarks. By its bare M and Cu wing veins, an inflated gonostylus, an apically located dorsal lobe with five long magesetae, and a richly setose intercoxal lobe on the hypopygium, the new species is similar to P. plusiochaeta Hippa & Vilkamaa, 1991 . But it differs from P. p l u s i o c h a e t a by a wider dorsal lobe on a more strongly inflated gonostylus, five much longer megasetae on the dorsal lobe, a tegmen with medial shoulders and a narrower intercoxal lobe on the hypopygium.

Etymology. This species is named after its long megasetae on the dorsal lobe on gonostylus, from the Latin adjective longispinus, meaning long megasetae.
