Distribution. China (Sichuan, Fig. 24).

Remarks. By its wing length, setose M and Cu1, and the shape of the intercoxal lobe on the hypopygium, the new species resembles P. latilingula. They may be distinguished by an apically located dorsal lobe on the gonostylus and its six megasetae, and a narrower tegmen in the hypopygium in P. ellipsoidea; a subapically located dorsal lobe on the gonostylus and its five megasetae in P. latilingula. By its apically located dorsal lobe on the gonostylus, P. ellipsoidea is also similar to P. plusiochaeta Hippa & Vilkamaa, 1991 and P. prosciaroides Hippa & Vilkamaa, 1991, but the latter two species have bare M and Cu wing veins.

Etymology. This species is named after its oval shape of the gonostylus, from the Latin adjective ellipsoideus, meaning oval.
