(Figs 5−6)

Holotype. Male, with labels: “Tenimber / Sunda Ins.”, “Stauding. u. Bang-Haas / Dresden, Ankauf 1961”, “Dresden / Coss 2”, “HOLOTYPUS / Panau tanimbari / Yakovlev & Hulsbosch, 2023 / Yakovlev & Hulsbosch des., 2022” (SNSD).

Paratype. 1 male, with same locality and date as for holotype (SNSD).

Description. Male. Length of forewing: 24 mm in holotype, 23 mm in paratype. Antenna short, about one-third of forewing in length; basal half of antenna bipectinate, with long setae (2.5−3.0 times as long as diameter of antenna stem); distal half of antenna unipectinate, with very short setae. Tegulae and patagia densely covered with light grey scales. Abdomen basally light grey, in other parts light brown, with light grey spots on dorsal surface. Forewing grey-brown; long light brown stroke from wing base to postdiscal area between veins of cubital stem; light brown stroke in medial area postdiscally; thin undulated longitudinal lines between veins of medial and cubital stems postdiscally; poorly expressed grey reticulated pattern submarginally; fringe dark at veins, light between veins. Hind wing grey-brown, without pattern; fringe dark at veins, light between veins.

Male genitalia. Uncus long, with acute beak-like apex, apical third noticeably thickened and deep longitudinal notch on lower surface. Gnathos arms thin, long, belt-like, not fused. Valve long, leaf-like, slightly curved along length, slightly narrowing to apex; outer margin semicircular; costal margin slightly curved; abdominal margin with small notch in proximal third. Juxta saddle-like, robust, with a pair of long leaf-like lateral processes. Saccus small, conical, apically acute. Phallus thick, with longitudinal folding on all surface; lateral surface of vesica with large finger-shaped cornutus almost equal to phallus in length.

Female unknown.

Comparison. Externally, P. tanimbari sp. nov. is close to P. variegatum, from which it differs in the less expressed light brown pattern on the forewing, thick distal third of the uncus, and less expressed notch on the abdominal margin of the valve in the proximal third.

Etymology. The new species is named after the region where it was collected, the Tanimbar Island.

Distribution. Indonesia: Tanimbar Island.
