description: Promalactis diorbis Kim and Park, sp. nov.   
(Figures 1E,F; 2C; 4 D–F)  
 Diagnosis   
 This species is similar to the Chinese species Promalactis punctuata Wang, in wing pattern of forewing, but it can be easily distinguished by the female genitalia, the sclerotized lamella antevaginalis and the corpus bursae with a pair of circular signa bearing tiny spines.   
 Description   
 Adult female (Figures 1E,F; 2C). Head: frons and vertex dark brown, tinged with deep grey, occiput with greyish-dark brown. Antenna with scape white dorsally, dark brown basally and ventrally, shorter than diameter of eye; flagellum white, alternated with dark brown. Second segment of labial palpus pale brown with dark brown distally; third segment dark brown except whitish apex, shorter than the former. Thorax and tegula dark brown near head, pale brown near abdomen dorsally. Wing expanse 8.0– 8.5 mm. Forewing ground colour brownish yellow, tinged with dark-brown scales near base, at two-thirds length of costal and posterior margins; costal patch oblique, white at two-thirds of costa; nine or ten white spots edged by fuscous scales on lower half of wing and near apex; two near wing base, one under costal patch, five or six under cell before tornus, one after tornus, and one near apex; fringes golden yellow after two-thirds of forewing outer margin. Hindwing lanceolate; fringes greyish brown throughout. Leg dark brown ventrally; hind tarsi with white at entire of first, apical part of second and third segments, basal and apical parts of fourth and fifth segments; hind tibia pale brown with two pairs of pale-brown spurs at sub-apex and base.   
 Male. Unknown.   
 Female genitalia (Figure 4 D–F). Apophysis posterioris two times longer than apophysis anterioris. Lamella postvaginalis characteristically shaped, caudal margin incised at middle, lateral margin folded, rarely setose at apex. Lamella antevaginalis sclerotized, well-developed as shown in Figure 4. Ductus bursae broad, gradually narrowing, with many spines on left side caudally, twisted once at three-quarters of length. Corpus bursae small, with a pair of circular signa.   
 Holotype. Female, Tam Dao Nat. Park, Vietnam, 450 m, 30 July 2006, Park, Chae and Cuong.   
 Paratypes. One female, Tam Dao Nat. Park, Vietnam, 100 m, 22 August 2002, KT Park, slide gen. no. SNU-9043; one female, same locality, 950 m, 14 August 2005, KT Park, gen. slide. no. SNU-9001.   
 Distribution   
Vietnam (North).  
 Etymology   
 The specific name of the new species is derived from the Greek di (= two) plus orbis (= circle), referring to a pair of circle-shaped signa.
