( Figures 1E, F , 2C , and 4A–C)

Diagnosis

This species is similar to Promalactis suzukiella (Matsumura) in the wing pattern, but can be distinguished by the rough surface of seventh sternite and a ring-shaped signum in the female genitalia.

Adult ( Figure 1E, F ). Head ( Figure 2C ): Frons greyish-brown; vertex dark brown. Antenna with scape white entirely; flagellum white dorsally. Labial palpus dark brown, except second segment, which is yellowish-brown ventrally; third segment same length as second segment. Thorax: Thorax and tegula yellowish-brown dorsally. Wing expanse 7.5–8.0 mm. Forewing ground colour yellowish-brown. White markings surrounded by fuscous scales, except apical margin; two oblique bands, one at near base, the other from one-third costal margin transverse to posterior margin, another white costal patch at two-thirds of forewing; two fuscous patches, one under costal patch mixed with pale grey, the other at subapical margin of forewing; fringes yellow from apex to tornus, followed by the outer margin, tinged with dark-brown scales near tornus. Hindwing more or less lanceolate; fringes greyish-brown. Legs: hind leg dark brown ventrally, except apical and basal parts of fifth, basal part of fourth and first segment of tarsus white.

Male genitalia. Unknown.

Female genitalia. (Figure 4A–C). Apophysis posterioris more than 2.5 times length of apophysis anterioris. Lamella postvaginalis incised medially on caudal margin with setose. Lamella antevaginalis incised medially on saw-like caudal margin. Surface of seventh sternite not smooth (Figure 4B). Antrum funnel-shaped, almost same length as papilla anales. Ductus bursae twisted once at two-thirds width. Corpus bursae with a doughnut-like signum.

Holotype
