Diagnosis. This new species can be distinguished from its allies by the forewing having a large rusty brown basal patch and a broad rusty brown median fascia. It is similar to P. ruficolor Meyrick, 1919  superficially, but can be distinguished by the absence of the lamella postvaginalis and the signum with denticles; in the latter species, the lamella postvaginalis is present and the signum bears large spines.

Description. Adult ( Fig. 5 View Figure ) wingspan 8.5−9.0 mm. Head with vertex blackish brown, frons silvery gray. Labial palpus black except white before apex of second segment and on dorsal surface of third segment. Antenna black, flagellum annulated with yellowish white on dorsal surface. Thorax and tegula light blackish brown. Forewing orange yellow, with a rusty brown basal patch and a broad median fascia: basal patch from between base and basal 1/4 of dorsum reaching below vein Sc, its outer margin triangularly protruded medially and edged with a white line; median fascia wide, from between basal 2/5 and middle of costal margin uniformly oblique outward to before tornus; apical spot cream white; cilia orange yellow. Hindwing and cilia grayish brown. Fore- and midlegs with ventral side white, dorsal side black, fore tibia with two white dots, mid tibia with an oblique cream white line at middle, tarsi white at apices of first and second tarsomeres; hindleg whitish yellow on ventral side, grayish brown on dorsal side except tarsus whitish yellow at apex of each tarsomere.

Male genitalia ( Fig. 13 View Figure ): Uncus wide at base, narrowed to basal 2/5, uniformly slender from basal 2/5 to before sharply acute apex. Gnathos slightly shorter than uncus, elongate narrow, with dense granules distally. Tegumen divided from posterior 1/5, widened medially, narrowed anteriorly, sclerotized along edges. Valva elongate, subparallel from base to about basal 2/3, then slightly narrowed to apex; costa slightly concave at base; ventral area setose from end of sacculus to apex, produced to a spine hooked dorsad and exceeding apex of valva. Sacculus wide at base, slightly exceeding middle of ventral margin of valva. Saccus shorter than uncus, triangular, rounded at apex. Juxta lobes symmetrical, narrowed distally, pointed at apex. Aedeagus longer than valva, strong; cornutus slender, extending from basal 1/7 to before apex or to distal 1/7 of aedeagus, curved at distal 1/6, pointed at apex, with a long strong spine and one or two short spines arising from its basal 2/5 or from before middle.

Female genitalia ( Fig. 17 View Figure ): Apophyses posteriores approximately 2.5 times as long as apophyses anteriores. Sternum with fine setae on posterior margin; tergum large, shallowly concave at middle on posterior margin. Ostium bursae wide. Antrum narrower than ductus bursae, deep concave in V shape posteriorly, with a longitudinal narrow crack along mid line. Ductus bursae membranous, basal half thickened except thinner basally, with sporadical denticles, distal half uniformly thinner. Corpus bursae rounded, finely spinous; signum being a sclerotized plate with denticles, placed posteriorly.

Distribution. Cambodia (Kampot, Kohkong, Pursat).

Etymology. The specific epithet is derived from the Latin granulosus, referring to the gnathos with dense granules distally.
