( Figures 1C, D , 2B , and 3E, F )

Diagnosis

This species is superficially similar to Promalactis jezonica (Matsumura) in the wing pattern, but can be distinguished by the irregularly shaped white markings and fuscous scales crossing the apical spot of the forewing.

Description

Adult ( Figure 1C, D ). Head ( Figure 2B ): Frons white; vertex dark brown. Antenna with white scape entirely, as long as diameter of eye; flagellum white and dark brown alternately. Labial palpus dark brown, except white apical and basal part of third segment; second segment 1.5 times longer than third segment. Thorax: Thorax and tegula dark brown dorsally. Wing expanse 7.0– 7.5 mm. Forewing ground colour dark brown; two white bands oblique surrounded by fuscous scales: one near to wing base, the other at one-sixth of costal margin, not reaching to posterior margin; one white costal patch at two-thirds, somewhat triangular-shaped, surrounded by fuscous scales; another white apical patch surrounded and crossed by fuscous scales, except outer margin above apex; two white short streaks rarely surrounded by fuscous scales under medial vein: one between second band and costal patch, the other one under costal patch; fringes yellowishbrown, tinged with greyish-brown from apex to half of outer margin. Hindwing more or less lanceolate; fringes greyish-brown. Legs: hind leg pale yellowishbrown, except apical parts of fifth and third segments and basal parts of first and second segment of tarsus.

Male genitalia ( Figure 3E, F ). Uncus bell-like, wide at base, gradually narrowed to apex; caudal margin of apex sclerotized. Gnathos thumb-like, wide at base, shorter than uncus. Valva symmetric; cucullus clavate with sclerotized, setose, flattened apex; processes of sacculus wide to apex, caudal margin of apex incised medially and setose. Aedeagus cylindrical, wide, shorter than sacculus; cornutus about half length of aedeagus.

Female genitalia. Unknown.

Holotype

One male, Cuc Phuong Nat. Park, Vietnam, 200 m, 1–2 July 2008, JB Heppner, slide gen. no. SNU-9334/ S Kim. Paratype. One male, same locality, 1–2 July 2008, JB Heppner, slide gen. no. SNU-9052/ S Kim.

Etymology

The specific name is derived from the Latin, alb - (= white) plus inpar (= irregular or uneven), referring to white irregular-shaped markings of the forewing.
