Promalactis curtifasciata Kim and Park, sp. nov. (Figures 1K, L, 2F, and 4H, I) Diagnosis This species is externally close to Promalactis odaiensis Park in the wing pattern, but it can be easily differentiated by the dark brown ground colour, from wing base to three-fifths of length, and tinged with yellow to apex in forewing and the absence of signum in the female genitalia. Description Adult (Figure 1K, L). Head (Figure 2F): Frons and vertex dark brown. Scape of antenna entirely white, except dark brown laterally, as long as diameter of eye; flagellum white and dark brown alternately. Labial palpus dark brown entirely, except white at basal and apical parts of third segment; second segment 1.5 times longer than third segment. Thorax: Thorax and tegula brown dorsally. Wing expanse 9.0– 9.5 mm. Forewing ground colour dark brown from wing base to three-fifths of length, tinged with yellow to apex; white markings: three short streaks from posterior margin and surrounded by fuscous scales: first at near base, second at one-sixth, third at two-sixths; one costal patch at middle; one apical spot after dense fuscous scales; fringes yellow beyond costal patch to apex followed by outer margin, dense and greyish-brown at half of posterior margin. Hindwing lanceolate; fringes greyishbrown. Legs: hind tibia pale yellowish-brown; tarsus pale yellowish-brown, but white at basal and apical parts of fifth, basal part of fourth and third segments. Male genitalia. Unknown. Female genitalia (Figure 4H, I). Apophysis posterioris twice as long as the apophysis anterioris. Lamella postvaginalis largely developed, incised at middle and setose. Lamella antevaginalis deeply incised, “U”-shaped. Antrum same length as papillae analis. Ductus bursae coiled, spinous anteriorly, vertical lined from two-thirds to corpus bursae. Corpus bursae pear-shaped, without signum. Holotype One female, Ba Be, Vietnam, 1080 m, 19–20 July 2010, JB Heppner, slide gen. no. SNU-9338/ S Kim. Etymology The specific name of the new species is derived from the Latin, curti (= short) plus fascia (= band), referring to three short band-like markings on the forewing. Distribution Oriental: Vietnam (North).
