( Figs. 1 H, 3D)

Diagnosis. This new species can be distinguished from other members of Tineovertex by the following characters: costa with a streak dilated in middle reaching nearly 1/6 across forewing, termen creamy white and apex gold yellow.

Description. Forewing length 6.0– 6.5 mm, antenna length 6.5–7.0 mm in female ( Fig. 1 H).

Male. Unknown.

Female. Head. Vertex and frons white. Thorax. Dorsum and tegula entirely white. Forewing creamy-white with apex gold-yellow around perimeter, about 4.2–4.4 × as long as wide including fringe (about 4.0–4.2 × as long as wide excluding fringe); costa with a broad irregular black streak from base to basal 2/3, dilated at middle and reaching 1/6 across wing; a distinct large gold-yellow digitiform stripe with black thin streak around from dorsum basal 3/8 to apex. Hindwing brownish gray, 2.3–2.5 × as long as wide including fringe (4.4–4.6 × as long as wide excluding fringe). Abdomen. Female genitalia ( Fig. 3 D). with eighth abdominal tergum flattened anteriorly with a distinct median keel, narrowed and rounded posteriorly with mass of long spines; eighth abdominal sternum semicircular in ventral view, ostium with two triangular projections and short bristles around. Ovipositor well sclerotized, corethrogyne scaling absent. Apophysis posterioris long and thick, about 1.5 × length of apophysis anterioris. Papilla analis strongly sclerotized, pointed, forming piercing apex with minute serration laterally. Corpus bursae large with a pair of long sword-shaped signa. Entire corpus bursae nearly equal in length to apophysis anterioris.

Material examined. Holotype, female, THAILAND: Chiang Mai, 7.V.1994, leg. I.J. Kitching et al., BM. 1994-97, with the genitalia slide No. 32139 in BMNH, deposited in BMNH. Paratypes, 2 females, THAILAND: Chiang Mai, Doi Pui, 1300 m altitude, 26–27.X.1985, leg. S. Moriuti, T. Saito & Y. Arita. Paratypes deposited in OPU.

Bionomics. Seasonal occurrence: May to October; the host is unknown.

Distribution. Thailand.

Etymology of specific epithet. From the type locality of Chiang Mai, Thailand.

Remarks. The new species is described from three female specimens. Although the females of five named Tineovertex species are still unknown, this species is distinct based on the diagnostic characters of the adults provided above.
