Remarks. By its wing length, setose M and Cu1, and subapically located dorsal lobe with four megasetae, the new species resembles P. latilingula Hippa & Vilkamaa, 1991, P. ungulata (Winnertz, 1867) and P. producta (Tuomikoski, 1960) . But the former two species differ from the latter two species in slightly larger body size. Moreover, P. angusta differs from P. latilingula by having a much slender 4th flagellomere, a narrower gonostylus, a narrower tegmen, and a sharper intercoxal lobe on the hypopygium.
Etymology. This species is named after its narrow gonostylus, from the Latin adjective angustus, meaning narrow.
