Diagnosis. The external characters of the species are similar to those of P. grata as follows: the forewing M1 and M2 are stalked at anterior angle of cell; the wing colour is greyish brown between the bases and the medial lines on all wings; the forewing antemedial line is pale yellow and broadening on the costa; the pale greyish brown bands outside the medial lines of all wings are indistinct and discontinuous; the fringes of all wings are pale yellow. However, P. hyalinata can be distinguished by the following characters: the forewing discal spot is more indistinct; the medial line of each wing is wavy, while in P. g r a t a, it forms a tooth on M3; the greyish brown bands outside the postmedial lines of all wings are narrower. The most distinct differences are in the male genitalia: the ventral lobe of the valva is broadly triangular with a pointed apex, the vesica has only basal cornutus. However, in P. g r a t a, the ventral lobe of the valva has a long curved projection apically; the vesica has both an apical and basal cornutus. In the female genitalia, the lamella postvaginalis in P. hyalinata is band-like, the lamella antevaginalis is broader and curved and the ductus bursae is only sclerotized posteriorly, whereas in P. g r a t a, the lamella postvaginalis is elliptical and the posterior margin is concave medially, the lamella antevaginalis is narrower and straight, and the ductus bursae is mostly sclerotized.
