( Figs 6 View FIGURES 1–8 , 40 View FIGURES 35–40 )

Description. Imago ( Fig. 6 View FIGURES 1–8 ) with wingspan 12.0 mm. Head dark yellow, vertex mixed with white laterally, frons yellow. Labial palpus with basal and second segments yellow; third segment dark ochreous brown except white at apex, shorter than second. Antenna with scape white; flagellum white and dark brown on dorsal surface, dark brown on ventral surface. Thorax, tegula and forewing dark yellow. Forewing with costal margin black along basal 1/4, with a triangular white spot at basal 2/3, extending posteriorly to midwing, its inside with a few darkbrown scales on costa, outside with dense dark-brown scales that form a weakly-defined dark-brown spot anteriorly; three white streaks arising from dorsal margin, edged with dark-brown scales: first one from basal 1/5 to above base of fold, second one from basal 2/5 to basal 1/3 of upper margin of cell, slightly arched, third one from 3/ 4 to near lower angle of cell; tornus with a triangular dark-brown spot, extending to lower angle of cell; small white elliptic spot at apex and at middle of termen respectively, margined with dense dark-brown scales; cilia yellow, dark gray along distal part of dorsum, tinged with white at tornus. Hindwing and cilia dark gray. Foreleg dark brown, tibia with white spot at base and middle on dorsal surface, with a tuft of short white scales at apex, tarsus with white spots on dorsal surface; midleg yellow, tibia and tarsus dark brown on dorsal surface, tibia with a white dot at base, with some white scales at middle, with a tuft of long white scales at apex on dorsal surface, tarsus with white spots on dorsal surface; hindleg pale yellow on ventral surface, yellow on dorsal surface, tarsus brown with white spots on dorsal surface.

Male genitalia ( Fig. 40 View FIGURES 35–40 ). Uncus broad at base, slightly narrowed to 3/5; distal 2/5 slender, tapered to bluntlypointed apex, narrowly folded inward laterally. Gnathos narrow and sclerotized, scobinate, slightly shorter than uncus, basal 2/3 parallel laterally, distal 1/3 roundly dilated slightly, rounded at apex; lateral arms narrow band shaped, about 1/3 length of gnathos. Tegumen branched from posterior 3/5, narrowly blunt anteriorly. Valva symmetrical, parallel dorso-ventrally; costa straight; apex deeply concave at middle, forming two processes: dorsal process short and narrow, thumb-like, setae sparse, with a small, semi-circularly lamellar process at apex; ventral process long and broad, about twice length and 1.8 x width of dorsal one, setose, rounded at apex. Sacculus broad at base, gradually narrowed to apex. Saccus about 3/4 length of uncus, broad at base, narrowed to rounded apex. Juxta narrow at base, with a slender basal handle reaching middle of saccus, concave near base laterally, broadest at 3/10, then gradually narrowed to bluntly-pointed apex, reaching posterior 1/3 of tegumen. Aedeagus thin and straight, almost same length as valva, with a small hill-like process near apex on dorsal side; cornutus absent.

Female unknown.

Diagnosis. This species is similar to P. dierli Lvovsky, 2000 . It can be separated by the forewing having a small elliptic white spot at middle of termen; the uncus without a process at basal 2/3, and the symmetrical valva in the male genitalia. In P. dierli , the forewing has no white spot on termen, the uncus has a triangular process at basal 2/3 on ventral surface and the valva is asymmetrical in the male genitalia.

Distribution. Burma (Bernardmyo).

Etymology. The specific name is derived from the Latin prefix exil - (= small) and Latin processus (= processa), referring to the small dorsal process near apex of the aedeagus.
