5. Anarsia deuterodes Park , sp. nov.

( Figs. 5 , 26 , 45 , 41 a–b)

Holotype: ♂, VIETNAM, Tam Dao Nat. Park, 910 m, 13 viii 2006 (KT Park, MY Kim, & MY Chae), gen. slide no. CIS-6442.

Diagnosis. This new species is superficially similar to A. isogona and the preceding species, A. incerta Ueda , but it can be distinguished from them by the much smaller size, with the wingspan less than 10 mm, while 17–18 mm in A. spatulatana , and the male genitalia with the tegumen having large, unique spatulate lobes laterally. The male genitalia are similar to those of A. spatulatana Park & Ponomarenko which was reported from Thailand, but the lobes are longer than those of A. spatulatana , and slightly narrowed toward apex, while A. spatulatana having enlarged apices, and the phallus is about 2/3 the length of the left valva with broadly expanded apex, whereas the length of phallus of the latter is about as long as the left valva.

Description. Adult: Male ( Figs. 5 , 26 ). Wingspan, 9.0 mm. Head creamy to pale grayish white. Flagellum of antenna with brownish annulations. Second segment of labial palpus in male ( Fig. 26 ) nearly quadrate, with a scale tuft anteriorly, densely covered with dark fuscous scales, creamy white along upper margin on outer surface, creamy white on inner surface, brownish antero-ventrally. Thorax same color with dorsal surface of head. Hind tibia slender, shiny whitish on outer surface, with long hair-like scales dorsally. Forewing elongate; ground color grayish white, brownish scales scattered irregularly, more dense in distal 1/3; costa slightly convex near 1/4 and abruptly oblique beyond middle, nearly straight medially; costal patch large, trapezoidal, dark brown near middle, occupying about 1/3 of costa and reaching 3/5 the distance across wing; apex more or less obtuse; termen oblique; fringe same with ground color of wing. No long hairpencil on the underside of forewing. Hindwing grayish white, hyaline, with brownish along veins; costa oblique beyond half, with anterior expansion. Female unknown.

Male genitalia ( Figs. 45, 45 a–b): Caudal margin of abdominal sternite VIII emarginated medially. Uncus slender, hook-like process, much exceeding the apices of socius. Width of socius much narrower than distal part of tegumen, with slightly curved beyond middle. Tegumen evenly narrowed distally, with long spatulate lobes in basal 1/3 of lateral margin, slightly narrowed toward apex; apex rounded. Valvae asymmetrical; left valva oval, inflated medially, with slender, heavily sclerotized, long process, about 3/5 the length of left valva, arising from near basal 1/3 and gently curved from basal 1/4; left valve with serrated costal margin, ventral margin nearly straight, apex rounded. Phallus curved, strongly ankylosed with juxta and vinculum, with a sclerotized longitudinal rod, as long as 3/5 of left valva, broadly expanded in distal 1/3.

Distribution. Vietnam (Vinh Phuc Prov.).

Etymology. The species name is derived from the Greek, deutero, meaning the second, with the Greek suffix, odes.
