Diagnosis.

This species shows a strong sexual dimorphism. In males, median and postmedian markings are white, and postmedian area is broadly suffused with white. In females, basal patch, median discoidal stigma and postmedian patch are reddish orange, and subterminal area is orange. Male hindwing displays an androconial organ on the dorsum. In male genitalia, gnathos projection is slender, ca. 1/3 of the uncus length, and juxta displays two conspicuous lateral projections at base, and a deeply indented apex. In female genitalia, the four loops formed by the ductus bursae is unique to this species.

Description.

Head. Antennae dorsally brown. Proboscis brown. Maxillary palpi brown, base and inner side pale yellow. Labial palpi brown, ventral base and inner side pale yellow.

Thorax (Figs 2 View Figures 1–3 , 43 View Figures 34–45 , 44 View Figures 34–45 ). Collar brown. Forewing length: 9-10 mm (♂ & ♀); forewing ♂ ground colour brown; basal narrow white streak, distally marked with yellow and orange; median discoidal stigma white, filled with few red and yellow scales, together with cubital and dorsal patch forming a white Y; postmedian patch brown speckled with red, more or less marked, distally with costal white streak; postmedian line marked on costal half; postmedian area with broad white suffusion; subterminal line conspicuously incurved inward at CuA2, white; fringe chequered brown and pale yellow; forewing ♀ (Fig. 44 View Figures 34–45 ) ground colour brown; yellow basal patch crossed by orange streak; median trapezoid white patch, filled to a various extend with yellow and red scales, together with cubital and dorsal white patches forming a Y; postmedian patch roughly oval, reddish orange, basally edged with yellow, distally with costal white streak; postmedian line marked on costal half; postmedian area faintly speckled with white between postmedian patch and subterminal line; subterminal line white, incurved inwards at CuA2; subterminal field marked with reddish orange and yellow; fringe brown with pale yellow dots. Hindwing pale yellow; in males, presence of an androconial organ on the dorsum of the hindwing. Forelegs bronze. Midlegs with femur brown; tibia brown, distally pale yellow; tarsi bronze. Hindlegs with femur brown; tibia pale yellow, speckled with brown; tarsi bronze.

Abdomen. Male tergite I, II partially sclerotised; tergite III sclerotised, with two shallow depressions on each side of middle, bearing patches of modified scales. Sternum A8 posterior margin straight.

Male genitalia (N = 3) (Fig. 82 View Figures 82–86 ). Uncus long and slender, basally narrow, medially slightly widened, narrowed at apical 1/4, apex spatula-shaped, ventrally with eight small ridges. Gnathos projection slender, ca. 1/3 of the uncus length. Valva gently bending dorsad from distal 1/3, dorsal margin slightly convex, apex roughly truncate, forming a furrow ring. Juxta mushroom-shaped, with base roughly rounded, slightly concave on its middle, with two conspicuous lateral extensions pointing outward, conspicuously narrowed at basal 1/4, apex bilobed. Saccus broad, triangular, pointing dorsad.

Female genitalia (N = 3) (Fig. 122 View Figures 119–122 ). Anterior apophyses with dorsal bump at posterior 1/3. Antrum sclerotisation short. Ductus bursae very long, forming four conspicuous loops bent before corpus opening. Corpus bursae small, globular, reticulated, medially with light broad sclerotised patch, with weak rounded sclerotisation at corpus opening. Thorn gently curved, with small dents pointing toward thorn base, basally with small outwardly projected extension.

Distribution.

Known from Wau and from Mount Susu in the Morobe Province (Papua New Guinea), at altitudes between 950 m and 1,200 m.

Phylogenetic relationships.

Etymology.

From the Latin jubatus, having a mane, referring to the dense hair covering on the inner side of the valva in male genitalia.
