( Figs 1, 2 View Figures 1–8 , 9, 10 View Figures 9–11 )

Paratypes. TAIWAN: 3 males, the same data as in the holotype ( MWM / ZSM) ; 1 male, Prov. Nan-Tou, 15 km N of Puli , 500m, 04.III.1996, Gy. Fábián & L. Németh leg., gen. prep. No.: ZSM Arct. 2021-285 (prepared by Volynkin) ( MWM / ZSM).

Diagnosis. The new species ( Figs 1, 2 View Figures 1–8 ) is externally well different from other congeners and is most reminiscent of the type species of the genus Disasuridia Fang, 1991 , D. rubida Fang, 1991 ( Figs 6 View Figures 1–8 , 13 View Figures 12–14 , 15 View Figures 15–16 ), from which, however, distinguished by the somewhat smaller size, the less elongate forewing, the thinner pattern elements of the forewing, the medially trapezoidal curved postmedial line (it is medially dentate in D. rubida ), and the narrower terminal black band of the hindwing, which is interrupted subapically and medially. The male genital capsule of A. wushipheri sp. n. ( Figs 9, 10 View Figures 9–11 ) is most similar to the recently described and externally dissimilar A. huaphanha Bucsek, 2020 ( Fig. 11 View Figures 9–11 ) and A. nigrubra Huang, Volynkin & Wang, 2020 ( Fig. 12 View Figures 12–14 ) but differs from the former species in the distally broader uncus, the posteriorly narrower arms of the tegumen, the broader, elliptical valva with the narrower and more distally positioned medial costal process, the lack of the distal costal process, and the shorter distal membranous lobe of the valva. The vesica of the new species bears only one cluster of more robust cornuti whereas A. huaphanha has two clusters of cornuti. Compared to A. nigrubra , the male genital capsule of A. wushipheri sp. n. has a proximally narrower uncus, a posteriorly somewhat narrower arms of the tegumen, a markedly broader, elliptical valva, a basally broader and less distally curved medial costal process, and a broader but shorter distal membranous lobe of the valva. The vesica of A. wushipheri sp. n. differs from A. nigrubra in the lack of the curved utriculous diverticulum, the fewer and basally narrower cornuti of the broad cluster, and the lack of the second, smaller cluster of the cornuti.

Description. External morphology of male ( Figs 1, 2 View Figures 1–8 ). Forewing length 7–8 mm. Head brick red, antenna pale brick red, weakly ciliate. Thorax brick red. Forewing broad, triangular, with rounded apex, smooth tornus and convex anal margin. Forewing ground colour brick red, pattern elements black. Subbasal spot dash-like, short. Antemedial area with four longitudinal dash-like spots. Antemedial line angled on vein R. Medial line slightly wavy medially. Discal spot small, almost circular. Postmedial line medially protruding outwards, trapezoidal curved in front of cell. Postmedial area with series of dashes of various lengths on veins. Cilia black. Hindwing pale scarlet, with broad black diffuse terminal band interrupted subapically, medially and at anal margin. Discal spot small, triangular, black. Cilia black. Abdomen pale scarlet. Male genitalia ( Figs 9, 10 View Figures 9–11 ). Uncus swollen, triangular in cross section, dilated medially and tapered apically, and with tiny thorn-like tip. Tegumen weakly sclerotised with posteriorly dilated arms. Tuba analis broad. Vinculum shorter than tegumen, heavily sclerotised, more or less U-shaped. Valva broad, elliptical. Costa strongly dilated medially, with basally broad, triangular medial costal process directed ventrally and somewhat curved inwards subapically. Distal membranous lobe of valva broad but very short. Sacculus narrow, setose, tapered distally, without distal process. Phallus narrow, cylindrical, somewhat dilated distally and with slightly dilated and rounded coecum. Vesica sack-like with distal-dorsal cluster of broad but short, flattened triangular cornuti, and medial-lateral semiglobular diverticulum bearing fine scobination. Vesica ejaculatorius originates subbasally on ventral side.

Female unknown.

Distribution. The new species is currently known from two localities in southern and central Taiwan Island (Pingtung and Nantou Counties).

Etymology. The new species is named after Dr Shipher Wu (Taipei, Taiwan), renowned expert in the Lepidoptera fauna of Taiwan Island.
