( Figs. 2 E–F, 3I)

Diagnosis. This new species can be distinguished from other members of Tineovertex with white vertex and pronotum by the following characters: termen creamy-white, vesica with cornuti indistinct, corpus bursae small without signum.

Description. Forewing length 8.5–9.0 mm in male, 12.5–14.5 mm in female; antenna length about 9.5 mm in male, about 14.0 mm in female ( Figs. 2 E–F).

Male. Head. Vertex and frons entirely white. Thorax. Dorsum and tegula entirely white. Forewing slender and long, about 5.0–5.2 × as long as wide including fringe (about 4.8–5.0 × as long as wide excluding fringe); costa with a broad irregular black streak from base to near apex, dilated in middle reaching about 3/7 across wing; subapical costa with two distinct white costal strigulae and two distinct dark black spots; apex with a dark black circular spot irrorated with white scales; a black streak along dorsum from basal 1/6 to tornus, an indistinct curved black streak present from tornus to apex. Hindwing relatively brown, 2.8–3.0 × as long as wide including fringe (4.5–4.7 × as long as wide excluding fringe). Abdomen. Male genitalia ( Fig. 3 I: left) with uncus lobes narrowly separated, basally enlarged and apical part triangular with apex hooked, about 0.5 × length of valva. Saccus rod-shaped, entirely slender, about 1.4 × length of valva. Valva rectangular, slightly constricted at middle, curved dorsally. Phallus slender and tapered; apical 1/4 part connate, vesica with cornuti indistinct.

Female. Very similar to male. Female genitalia ( Fig. 3 I: right) with corpus bursae small, lacking signum. Entire corpus bursae about 1/4 × length of apophysis anterioris.

Type material. Holotype, male, MALAYSIA: Pahang, 11–29.XI.1981, leg. K.R. Tuck, BM. 1981-549, with the genitalia slide No. 32141 in BMNH. Paratypes, 1 male, MALAYSIA: Perak, Gunong Hijan, 1891, leg.

Barlow, BM. 1986-312, with genitalia slide no. 32143 in BMNH; 1 female, BRUNEI: Upper Temburong, 21.VI.1981, leg. T.W. Harman, BM. 1989-124, with genitalia slide no. 32144 in BMNH. All types deposited in BMNH.

Bionomics. Seasonal occurrence: February to November; the host is unknown.

Distribution. Malaysia, Brunei.
