Diagnosis. This species is similar to A. inouei sp. nov., their differences being compared in the diagnosis part of the two preceding species.

Description. Adult (Figs 7,8). Wingspan 25–26 in males (n= 5); 26 in females (n= 1). Antenna ciliate, male with a pair of long bristles on each segment, bristles as long as the diameter of shaft in median region. Head, thorax rosy-red, abdomen pinkish-ochreous. Forewing apex pointed; outer margin smoothly excurved; ground coloration rosy-red, costal margin black; transversal lines prominent, dark grey, antemedial line double peaked, medial line stout, nearly straight, postmedial line curved outward from costal margin to CuA1, then becoming straight towards tornus; submarginal striae long, prominent; marginal scales dark grey. Hindwing reddish ochreous; medial line light grey, wide, indistinct; marginal scales dark ochreous. Male genitalia (Figs 13,14). Uncus sclerotized, slightly curved downward at medial part, apex tapering; tegumen long and narrow; vinculum short; saccus U-shaped; juxta sclerotized, plate-like; valva sclerotized, costal margin protruded at medial part, distal part round, one ventral process arising from ¾ part of costal margin from base, apex round with dense spinose tufts; sacculus stout, one ventral process arising from ⅓ part from base with dense, stout spinose tufts at apex, distal part of sacculus process hook-like and strongly sclerotized. Aedeagus stout, spinose patches arising from two lateral sides of manica; dorsal part of vesica scobinate, basal part expanded, gradually tapering distally, two moderate spinose patches and a weak sclerotized plate arising from dorsal part of vesica. Female genitalia ( Fig. 16 ). Ovipositor lobes membranous with short hair-like setae; apophyses elongated, length of anterior and posterior ones equal. Ostium bursae sclerotized, stout, ventral part strongly and widely incised (V-shaped); ductus bursae very short, sclerotized; corpus bursae sac-like, posterior ⅓ part covered densely with short spinules and scobination, this covering extends toward fundus bursae at left side; ductus seminalis arising from medial part of corpus bursae.

Etymology. Dedicated to Yasunori Kishida, an expert on Asiatic arctiine moths.

Notes. This species is endemic to Taiwan, and occurs in mid-elevations in broad-leaved forests in central Taiwan. It is probably univoltine, the adults are on the wing in June and July. The immature stages remain unknown.
