Diagnosis. This species is similar to A. nemoralis (Scopoli, 1763) in the male genitalia by the costa of the valva produced to an elongate process distally, but it can be separated by the ventral part of the valva with a long apical spine, the triangular uncus, and the phallus with one curved needle-like cornutus. In A. nemoralis, the ventral part of the valva is produced to a long process distally, the uncus is papillary, and the phallus has a crescent cornutus (Li et al. 2012: 565, fig. 369).
Description. Adult (Fig. 3) wingspan 16.0–20.0 mm. Head with vertex orange, frons fuscous. Antenna yellow- ish brown, with black ring dorsally, cilia in male approximately as long as diameter of flagellomere. Labial palpus blackish brown mixed with yellowish white scales. Maxillary palpus yellowish white, fuscous distally. Scales at base of proboscis black mixed with yellowish white. Patagium, tegula, and thorax yellowish white with orange dots. Forewing sub-triangular; basal 1/3 yellowish white mixed with orange, terminally edged by antemedial line, distal 2/3 purplish grey; costal margin yellow, with a black spot near base; antemedial line black and orange, from basal 1/3 of costal margin oblique outward to near basal 1/3 of dorsum; discoidal stigma oval, orange intermixed with black scales; postmedial line black, darker on costa, from distal 1/4 of costal margin sinuate to basal 1/3 of CuA 1, thereafter recurved inward to middle of CuA 2, finally extending to distal 1/3 of dorsum; terminal margin black; cilia blackish brown except yellowish white below apex and above ventral corner of termen. Hindwing fan-shaped; basal 1/3 yellowish white mixed with a few orange scales, distal 2/3 purplish grey except yellowish white along costal margin and dorsum; posterior angle of cell with a black spot; between near base of CuA 2 and middle of 1A with diffused black and orange scales; postmedial line blackish brown, weakly extending from distal 1/3 of costal margin to near middle of CuA 1, then recurved inward to near basal 1/3 of CuA 2; longitudinal black and orange streak above 3A; terminal margin black; cilia blackish brown, yellowish white mixed with blackish brown at tornus. Legs yellowish white, mixed with blackish brown on fore coxa ventrally, as well as on inner side of fore femur and tibia, black on 4 th and 5 th tarsomeres and at apices of 1 st and 3 rd tarsomeres.
Male genitalia (Fig. 7). Uncus triangular, shorter than basal width, rounded and with a few setae apically. Transtilla arising from basal 1/3 of costa, narrowed medially, conjunct. Valva narrow at base, widened to about middle; distal half divided: costal part suddenly produced from middle to a pointed apex, forming an elongate narrow process bearing a tuft of setae at base; ventral part much shorter than costal part, obtuse ventrally, with a long apical spine; costa band-like, terminating in middle of costal margin; clasper slender, slightly curved, arising from below base of costa. Saccus sub-rectangular, obtusely rounded anteriorly. Juxta shield-shaped, distal half bifid. Phallus slightly shorter than valva, with a small, needle-like cornutus, with two oval sclerites before apex.
Female genitalia (Fig. 9). Apophyses anteriores approximately 1.5 times length of apophyses posteriores. Antrum tube-shaped, furcate, narrowed and divergent posteriorly. Ductus bursae about 1/3 length of corpus bursae. Ductus seminalis originating from posterior end of corpus bursae. Corpus bursae oblong, with spinules on anterior 1/4 laterally; signum absent.
Distribution. China (Hainan).
Etymology. The specific name is derived from the Latin aculeatus, referring to the long apical spine of the ventral part of the valva.
