Diagnosis. Notarcha aurolinealis can be diagnosed by the whitish forewing with the ochreous undulating medial lines, the three small black dots on the costa, one large black discal dot, and the whitish hindwing with ochreous medial lines. Notarcha aurolinealis is externally similar to N. quaternalis (Zeller, 1852) in wing color and wing pattern elements, but can be distinguished by the large black discal dot on the forewing.

Description. Wingspan 16–18mm. Antennae filiform; frons broad, yellowish white; maxillary palpi minute, tip white; labial palpi moderate in length, about twice to eye diameter, yellowish white. Body white. Forewing white in ground color; basal part costally with a black minute dot, basal line ochreous, undulating, slanted, costally with a black dot; antemedial line ochreous, slanted, weakly undulating; postmedial line ochreous, medially projected, strongly incurved, costally with a black dot; central fascia broad, tapered from middle to dorsum, a large black discal dot; subtermen with an ochreous rounded line; fringe ochreous. Hindwing white in ground color; basal and antemedial lines ochreous, slanted, relatively thick; postmedial line ochreous, strongly undulating; subtermen ochreous band, costally tinged with light brown scales. Male genitalia. Uncus long, triangular, basally thicker, distally tapered, apex obtuse; gnathos simple; saccus basally expanded, medially projected. Valva broad; costa basally expanded, medially tapered; fibula long spinular process with weakly curled tip; sacculus relatively thicker. Aedeagus cylindrical, about 3–4 long spinular cornuti. Female genitalia. Papillae anales small; posterior apophyses thin, slightly longer than 8 th segment; anterior apophyses basally thicker, gradually tapered distally, long as 1.5 times as 8 th segment; ostium bursae long, funnel-shaped, sclerotized, anteriorly narrowed; ductus bursae short, medially sclerotized with bristles along the bursae, with a pouch-shaped sclerotized appendage; corpus bursae long, elliptical, posteriorly with ductus seminalis, signum absent.

Distribution. South Korea, China ( Hong Kong), Philippine, Thailand, India, Indonesia, Singapore, Myanmar, New Guinea, and Australia.

DNA barcoding. One specimen from South Korea ( OK501206 ) was sequenced, and the genetic difference between N. aurolinealis and its relative, N. quaternalis (Zeller) was 6.4%.

Remarks. The genus Notarcha comprises 18 species worldwide, showing high diversity in the Oriental region ( Nuss et al., 2003 –2021). N. quaternalis feeds on Sida rhombifolia (Malvaceae) in Japan.
