( Figs. 15 , 36 , 56, 56 a–b, 65)

Holotype: ♂, VIETNAM, Bac Khan Prov., Ba Be Nat. Park, 26–28 vii 2006 (Park, Chae, & Cuong), gen. slide no. CIS-6408. Paratypes: 8 ♂, 1♀, same data as the holotype, gen. slide no. CIS-6409 & -6410 (♂), -6450 (♀).

Diagnosis. This species can be distinguished from its allies by the head densely covered with dark fuscous scales, the second segment of labial palpus ( Fig. 36 ) trapezoidal, and the underside of fore and hindwing dark fuscous above the lower margin of discal cell to 2/3 the length of wings. The male genitalia are characterized by having a tapered process arising from beyond 2/3 of the ventral margin.

Description. Adult: Male ( Figs. 15 , 36 ). Wingspan, 11.5–12.0 mm. Head dark fuscous dorsally. Antenna about 3/4 the length of forewing; scape elongate, grayish white speckling with dark fuscous scales; flagellum grayish white, with pale brown annulations. Second segment of labial palpus in male ( Fig. 36 ) quadrate, with broadly truncated apex; densely covered with dark fuscous scales on outer surface throughout; in female, third segment slender, dark fuscous in basal 2/3, grayish in distal 1/3. Tegula dark fuscous dorsally and also dark brown on anterior margin. Thorax grayish white speckled with dark fuscous scales. Fore and mid-tibia covered with dark fuscous scales ventrally; hind tibia yellowish brown on outer surface, without long hairs dorsally. Forewing elongate; ground color grayish white to pale orange gray, brownish scales scattered irregularly, more dense in distal 1/3; costa with a blackish short streak near base; slightly curved near 1/4, nearly straight medially, abruptly oblique beyond 3/4; costal patch more or less narrow, crescent, preceded and followed by two dark fuscous, small dots; apex more or less obtuse, blackish scales along margin before and beyond apex; termen strongly oblique, with dark fuscous scales along margin inwardly; fringe orange white in basal 1/3, grayish beyond, speckled with dark brown scales; underside dark fuscous to 2/3, above the lower margin of discal cell, without a long hair pencil on the underside. Hindwing grayish; anterior expansion abruptly truncate beyond middle; underside costal half dark fuscous in basal 2/3; apex acute.

Male genitalia ( Figs. 56, 56 a–b). Abdominal sternite VII with hat-shaped membranous flap ( Fig. 50 b). Uncus short, less than 1/2 the length of socius; socius ovate, large, width as wide as distal end of tegumen; Tegumen narrowed towards apex, slightly expanded at middle. Left valva large, elongate, acute apically, with a long, Sshaped, tapered process, arising from beyond 2/3 of ventral margin, extended to base of valve and with a large membranous pouch before middle; patch of long-stalked palmately modified scales occupying beyond the process. Right valva narrow in basal 1/4, then broadened and gradually narrowing towards apex, with a small triangular process near 1/3 and a large triangular process near 2/3; patch of scales similar to left valva. Saccus short, slender. Phallus taenioid, curved medially, broadened beyond 3/4.

Female genitalia ( Fig. 65 ). Abdominal tergite VII with a small crescent membranous flap medially, connected with weakly sclerotized rings curved to antero-lateral corners. Apophyses anteriores short, about 1/2 length of apophyses posteriores. Ostium bursae deeply concave on caudal margin, funnel-shaped. Ductus bursae narrow, more than two times of corpus bursae in length. Corpus bursae oblong, weakly speculate on internal surface; signum long, transverse, sclerotized ridge with weakly sclerotized triangular plate beneath.

Distribution. Vietnam (Bac Khan Prov.).

Etymology. The species name is derived from the Greek, melano (= black), with a Greek suffix, odes, denoting resemblance.
