Panau variegatum ( Roepke, 1957)

( Figs 1–2 )

Xyleutes variegata Roepke, 1957: 28–29 , pl. 2, fig. 3, pl. 8, figs 4–4a (“ Xyleutes variegata spec. nov. ”).

Panau variegata: Schoorl, 1990: 166 ; Yakovlev, 2011: 72.

Type locality. “Tonsea Lama, North Celebes” [ Indonesia, North Sulawesi, Minahasa Regency , 1°19′26.2″N 124°57′17.8″E] .

Type material examined. Holotype. Male, with labels: “N. Celebes. / M. Tonsea Lama / 18 Maart 1920 / Mus. Leiden.”, “Typus / Holo / Roepke”, “Museum Leiden / verzameling / W K J Roepke”, “ Panau variegata ” (NBCL) .

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

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

Remarks. Female is unknown. One of the paratypes, kept in NHMUK, was collected in New Guinea without indicating the exact location on the label ( Roepke, 1957: 29). Its species affiliation will be checked later.

Distribution. Indonesia (Sulawesi Island),? New Guinea.

Flight period. The type series was collected from March to July.
