( Figs 7 View FIGURES 1–8 , 36 View FIGURES 35–40 )

Type material. Holotype ♂, VIETNAM: Ninh Binh Prov.: Cuc Phuong Nat. Park , 450 m, 14 vi 2004, leg. KT Park & N Cuong, gen. slide no.CIS-6680, in NIBR.

Description. Adult ( Fig. 7 View FIGURES 1–8 ). Wingspan 11.0 mm. Head dark brown dorsally; frons orange gray. Ocellus absent. Antenna with scape deep brown on dorsal surface, pale yellow on ventral surface; flagellum yellowish brown with dark-brown annulations dorsally, yellowish brown ventrally, with fine cilia. Second segment of labial palpus dark brown on outer surface, grayish yellow on inner surface, with grayish white-tipped triangular scale tuft dorsally; 3rd segment smoothly clothed, shorter than second, pale yellow except dark brown on ventral surface. Thorax and tegula dark brown; mesothoracic anepisternum without hair-pencils in male. Hind tibia dark brown on outer surface, grayish white on inner surface, tarsomeres grayish white apically on outer surface. Forewing elongated; ground color dark brown; a small, pale-yellow costal streak at distal 1/4 of costa; a pair of discal black spots, larger one placed at basal 2/3 of cell and smaller one at end of cell; plical spot similar to discal spot at basal 2/3 of fold; apex more or less obtuse; termen oblique, nearly straight, with black line along margin; fringe concolorous with ground color, with narrow yellowish-white basal line. Hind wing brownish gray; fringe conclorous with ground color.

Male genitalia ( Fig. 36 View FIGURES 35–40 ): Uncus broadened with posterior margin bluntly rounded, sparsely setose. Gnathos heavily sclerotized, C-shaped, acute apically. Valva much longer than tegumen plus uncus, rounded apically; valvella about 1/6 the length of valva, gradually narrowed to sharp apex, setose. Vinculum about 3/5 the length of tegumen plus uncus; lateral lobes arising from distal 5/7 of vinculum, about 2/3 length, triangularly extended to sharp apex, setose apically. Saccal region broad, slightly concave on anterior margin medially. Sicae slender, paired lobes, fused basally, nearly symmetrical. Aedeagus shuttle-shaped; basal zone triangular, truncate at apex; two sclerotized, asymmetrical processes arising from left side of zone, sharply pointed apically, longer one about 3/5 the length of aedeagus and shorter one about 2/5 length.

Female unknown.

Distribution. Vietnam (Ninh Binh).

Diagnosis. The new species resembles Dichomeris parallelosa Park & Ponomarenko, 1998 , but it differs from the latter by the aedeagus with two sclerotized lobes from the zone and a hook-shaped lobe absent. In D. parallelosa , the aedeagus has three sclerotized lobes from the zone, and one of them is hook-shaped.

Etymology. The specific name is derived from the Latin, -flav (= yellow) and maculatus (= spotted), referring to the yellow spot at costal 3/ 4 in the forewing.
