Huang, Guo-Hua, Hirowatari, Toshiya & Wang, Min, 2011, A revision of the genus Tineovertex Moriuti (Insecta: Lepidoptera: Tineidae), with descriptions of five new species, Zootaxa 2991, pp. 1-12 : 10

Tineovertex fibriformis , sp. nov.

( Figs. 2 C–D, 3H)

Diagnosis. This new species can be distinguished from other members of Tineovertex that have a white vertex and pronotum by the following characters: uncus lobes narrowly separated, short, and hooked with apical 1/3 filamentshaped; valva spatulate with apical 2/3 gradually becoming broad; and phallus with a forked apex.

Description. Forewing length about 6.8 mm in male, about 7.7 mm in female; antenna length about 7.0 mm in male, about 8.0 mm in female ( Fig. 2 C–D).

Male. Head. Vertex and frons white. Thorax. Dorsum and tegula white. Forewing creamy-white with apex black, about 5.5–5.6 × as long as wide including fringe (about 5.2–5.3 × as long as wide excluding fringe); costa with a broad irregular black streak from base to basal 2/3, dilated in middle reaching 1/3 across wing; a narrow and nearly straight black streak along dorsum and termen from dorsum base to apex, irrorated gold-yellow scales. Hindwing brownish gray, 2.3–2.4 × as long as wide including fringe (4.1–4.2 × as long as wide excluding fringe). Abdomen. Male genitalia ( Fig. 3 H: left) with uncus lobes narrowly separated, short and hooked, about 0.4 × length of valva, curved ventrally, apical 1/3 filament-shaped. Saccus entirely rod-shaped, slightly longer than valva in length. Valva spatulate, basal 1/3 narrow, apical 2/3 gradually broadened, apex rounded. Phallus nearly straight, basal part swelling, apex forked, about 1.1 × length of valva; vesica with cornuti consisting of mass of minute spines.

Female. Very similar to male. Female genitalia ( Fig. 3 H: right) with corpus bursae small, spherical, bering a pair of large wedge-shaped signa. Entire corpus bursae very long, about 1.8 × length of apophysis anterioris.

Type material. Holotype, male, MALAYSIA: Cameron Highlands, 15–23.VIII.1986, leg. G.S. Robinson, BM. 1986-299, with genitalia slide no. 32136 in BMNH. Paratype, 1 female, same data to holotype, except genitalia slide no. 32137 in BMNH. All types deposited in BMNH.

Bionomics. Seasonal occurrence: August, with host unknown.

Distribution. Malaysia.

Etymology of specific epithet. From the Latin fibriformis (=like a filament), referring to the uncus with apical 1/3 filamentose.

Remarks. The new species is known only from Malaysia.
