Description. Male ( Figs 6–7 View Figures 1–9 ). Flagellum covered with speckled brown and dark brown scales. Head, thorax and abdomen dark brown. Forewing. Forewing length: 24–26 mm. Long, semilanceolate with bunt apex. Background color dark brown. Pattern consists of diagonal contrasting lines. Fringe dark brown. Hindwing. Somewhat tapezoid with concave outer margin. Background color and fringe dark brown. Genitalia ( Figs 14 View Figures 10–14 , 17 View Figures 15–17 ). Vinculum a narrow band slightly widening medially. Socii papilla-shaped, sclerotized and covered with setae. Cucullus elongated, finger-shaped with blunt apex, covered with setae. Sacculus elongated, slightly longer than cucullus, c-shaped, densely covered with setae, apically bears small dents. Juxta nearly reduced, medioventrally fused with aedeagus. Aedeagus c-shaped with large ventroapical spur. Vesica large, trapezoid, dorsally has two short extensions. Vinculum ventrally elongated, bears cubile. Cubile clearly divided medially into a pair of somewhat triangle processes with mediodistal spur. Female remains unknown.
Diagnosis. Adult males of P. arienne sp. n. are very dark brown with concave external margin of hindwings ( Figs 6–7 View Figures 1–9 ), have large vesica, large ventroapical spur in aedeagus, and fully split lobes of cubile ( Figs 14 View Figures 10–14 , 17 View Figures 15–17 ), while adult males of P. subfascia are brown with convex dentated external margin of hindwings ( Fig. 1 View Figures 1–9 ), have small vesica, brely pronounced spur in aedeagus, and fused lobes of cubile ( Fig. 10 View Figures 10–14 ).
Adult males of P. arienne sp. n. are very dark brown with concave external margin of hindwings ( Figs 6–7 View Figures 1–9 ), have large vesica, large ventroapical spur in aedeagus, and fully split lobes of cubile ( Figs 14 View Figures 10–14 , 17 View Figures 15–17 ), while adult males of P. bogema are brown with convex external margin of hindwings ( Fig. 2 View Figures 1–9 ), have small vesica, small ventroapical spur in aedeagus, and half-fused lobes of cubile ( Fig. 12 View Figures 10–14 ).
Adult males of P. arienne sp. n. are very dark brown with concave external margin of hindwings ( Figs 6–7 View Figures 1–9 ), have large vesica, large ventroapical spur in aedeagus, and fully split lobes of cubile ( Figs 14 View Figures 10–14 , 17 View Figures 15–17 ), while adult males of P. ckabik are brown with convex dentated external margin of hindwings ( Fig. 3 View Figures 1–9 ), have small vesica, small ventroapical spur in aedeagus, and fused lobes of cubile ( Figs 15–16 View Figures 15–17 ).
