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.

Biological notes. The larva of P. hyalinata was described by Sevastopulo (1946, as aerata ) and Singh (1957). Hypericum sp. ( Hypericaceae ) was recorded as a host-plant in India by Sevastopulo (1946).
