Diagnosis. This new species has a similar forewing pattern as I. obliquella , but can be distinguished by the fol-

Description. Male (Fig. 7E). Wingspan 16 – 17 mm. Head: yellowish white to pale yellow in frons and dorsal surface. Antenna with basal segment elongate, yellowish white ventrally and dorsally, with dark-brown bands at lateral sides; flagellum yellowish white throughout. Labial palpus with thickened 2 nd segment, yellowish white, speck- ling with brownish scales in basal 1/3 on outer surface, yellowish white on inner surface; 3 rd segment shorter than 2 nd segment, dark brown dorsally, yellowish white ventrally. Thorax: yellowish white dorsally with two longitudinal blackish bands; tegula dark brown, with creamy-white scales along posterior margin. Hind tibia with long, rough scales beyond median spurs. Forewing slightly dilated distally; ground color creamy white to yellowish white, with pale yellow scales densely covered in upper 1/3; antemedian band broad, dark brown, slightly convex medially; postmedian fascia dark brown, broadly developed, followed by a large, dark-brown, overlapping triangular outer fascia, bordered by a yellowish-white line; subterminal fascia dark brown, as wide as antemedian band, reaching apex; costa slightly arched around basal 1/3 and oblique beyond 3/4; apex obtuse; termen slightly concave before middle, with narrow dark-brown band along margin; fringe grayish white, except some dark-brown scales at apex. Hindwing broader than forewing, with weak, narrow, dark-brown postmedian band and dark- brown line along termen, more distinct in apical half; apex acute; termen oblique, slightly concave medially; fringe grayish white, with narrow, weak brownish basal line.

Male genitalia (Figs. 9A, B): Uncus more or less broad with rounded apex. Gnathos narrower toward apex, strongly bent beyond 2/3, with sharply pointed apex. Tegumen broad, weakly sclerotized. Valva broad, nearly parallel-sided, with a small spine at apex; costal margin gently oblique near base, then concave medially; ventral margin nearly straight. Juxta shield-shape, concave medially on caudal margin. Aedeagus more or less slender, slightly longer than valva, bent medially; cornutus absent. Abdomen with spinous zones on tergites, segment VIII without specially modified sclerite (Fig. 9C).
