Tineovertex elongata Huang, Hirowatari & Wang, 2011, sp. nov.

Tineovertex elongata, sp. nov.

(Figs. 2 I, 3K)

Diagnosis. This new species is very similar to T. antidroma (Meyrick, 1931), but the two can be distinguished by the slender ventral process of the uncus — very long in T. elongata, very short in T. antidroma.

Description. Male. Forewing length 6.3–7.2 mm, antenna length 5.5–6.5 mm (Fig. 2 I; also see Huang et al., 2007: fig. 2C).

Male. Head. Vertex pale white. Frons pale brown. Thorax. Dorsum smooth white, tegula white except anterior black margin. Forewing elongate with apex rounded, about 2.4–2.8 × as long as wide including fringe (about 3.3– 3.4 × as long as wide excluding fringe); costa with a faint irregular black streak from base to near apex, dilated at middle where it reaches 1/3 across wing; a narrow and indistinct black streak along termen from dorsum beyond middle to apex. Hindwing brownish gray. 1.8–1.9 × as long as wide including fringe (3.3–3.6 × as long as wide excluding fringe). Abdomen. Male genitalia (Fig. 3 K; also see Huang et al. 2007: fig. 6) with uncus elongate triangular, lobes narrowly separated, vertically-curved ventrally at middle with apex narrow and pointed. Saccus elongate, rod-shaped, about 1.4 × length of valva. Valva rectangular, gradually broader apically. Phallus nearly straight, about 1.8 × length of valva; apex with a pointed process slightly curved ventrally; vesica with cornuti consisting of mass of thick spines.

Female. Unknown.

Paratypes. 1 male, THAILAND: Loei, Phu Rua, 800 m altitude, 15–19.VIII.1987, light trapping, leg. S. Moriuti, T. Saito, Y. Arita & Y. Yoshiyasu; 1 male, THAILAND: Chiang Mai, Doi Inthanon, 1300 m altitude, 1–3.XI.1985, light trapping, leg. S. Moriuti, T. Saito & Y. Arita. Paratypes deposited in OPU.

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

Distribution. China (Hainan), Thailand.

Etymology of specific epithet. From the Latin elongata (= long), referring to the very long the bilobed narrowly long separated uncus being vertically-curved ventrally at middle of the male genitalia.

Remarks. This new species was previously misidentified as T. antidroma (Meyrick, 1931) by Huang et al. (2007) owing to their similar appearance. Examination of the type material revealed that genitalia of these two species are quite different.
