Fujimacia dayaoensis sp. nov.

( Figs 3 , 11 )

Type material. China, Guangxi Zhuang Autonomous Region: Holotype: ³, Yinshan Park (24.15°N, 110.21°E), Dayaoshan Nature Reserve , Jinxiu County, 1364 m, 19-VII-2015, leg. Mujie Qi, Shengnan Zhao, genitalia slide No. QMJ15294.

Diagnosis. This species is similar to F. bicoloralis superficially, but it can be distinguished from the latter by the basal and terminal areas of both fore- and hindwings fuscous, the median area of the hindwing grayish-brown; and by the valva without apical process, and the distal 2/5 of the valva paralleled on dorsal and ventral margin in the male genitalia. In F. bicoloralis , the basal and terminal areas of the forewing and the entire hindwing are reddish brown mixed with fuscous scales ( Fig. 1 ); and the apical process of valva is thorn-shaped, and the distal part of the valva is gradually narrowed to apex in the male genitalia, ( Fig. 9 ). Fujimacia dayaoensis sp. nov. mostly resembles F. gracilenta sp. nov. superficially, and the differences between them are stated under F. gracilenta sp. nov.

Description. Adult ( Fig. 3 ). Wingspan 20.0 mm. Frons and vertex covered with pale yellowish-brown scales. Labial palpus of male yellowish-brown on outer side, slightly mixed with fuscous scales on second and third segments, first segment equal to third, about 1/3 length of second. Maxillary palpus pale yellowish-brown, about 1/4 length of second segment of labial palpus.Antenna of male with scape dilated slightly, flagellum with cilia ventrally. Patagium and tegula grayish-brown. Forewing yellowish-brown; basal area grayish-brown except fuscous along costa and inner side of antemedial line; median area with seldom fuscous scales, terminal area fuscous except grayish-brown apex below costa; antemedial line pale yellowish-brown, from basal 2/5 costa arched outward to basal 1/3 of dorsum, edged with indistinct fuscous line on outer side; postmedial line same color as median area, edged with fuscous line on inner side, from distal 2/5 of costa to distal 1/4 of dorsum sinuously; distal discoidal stigma fuscous; cilia fuscous except brown at base. Hindwing fuscous except grayish-brown at median area; ante- and postmedial lines grayish-brown, sinuous, inner side of postmedial line and outer side of antemedial line edged with bold fuscous lines, respectively; cilia same as that in forewing. Foreleg fuscous, mixed with yellowish-brown scales slightly, each apex of tarsomere brown; midleg fuscous, tibia with yellow scales from 1/2 to distal 4/5, tarsus fuscous mixed with brown scales; hindleg yellowish-brown, mixed with fuscous scales slightly.

Male genitalia ( Fig. 11 ). Uncus conical at distal half, rounded at apex, with sparsely setae at dorsal and ventral sides, basal half of uncus semi-circular, basolateral process rectangular, slightly curved at dorsal margin. Gnathos lateral arms slim, medial lobe trapezoidal, distal process sub-oval, about 1/3 length of uncus. Valva with basal 3/5 rectangular, distal 2/5 cylindrical, about 1/2 width of basal half, pointed at apex; setose at ventral margin of distal 2/5 of valva; sacculus broad at base, gradually narrowed towards apex, about 3/5 length of valva; apical process absent. Juxta sub-oval, concave in U shape posteriorly. Saccus conical, same length as juxta. Phallus with basal bulb 2/3 as long as distal part, distal sclerite weakly sclerotized, curved ventrally, cornutus about 2/3 length of phallus.

Female genitalia. Unknown.

Distribution. China (Guangxi).

Etymology. The specific name is derived from the type locality, Dayao Mountains in Jinxiu County, Guangxi Zhuang Autonomous Region.
