Tineovertex gladiata Huang, Hirowatari & Wang 2007: 40 (type locality: China (Guangdong)).

Diagnosis. This species is similar to T. melanochrysa , but it can be distinguished by the following characters: in T. gladiata the mesonotum and tegula are entirely black; the phallus is cylindrical and stout; and the corpus bursae has a pair of large sword-shaped signa. In T. melanochrysa the posterior region of the mesonotum and the tegula are pale yellow; the phallus is stout basally and tapered apically; and there are two thorn-shaped signa the corpus bursae.

Description. Forewing length 5.5–6.0 mm in male, 6.5–7.0 mm in female; antenna length about 6.0 mm in male, about 7.0 mm in female ( Figs. 1 D–E; also see Huang et al., 2007: fig. 1A–B).

Male. Head. Vertex and frons black. Thorax. Dorsum and tegula entirely blackish. Forewing with apex and termen gold-yellow, about 3.6–4.0 × as long as wide including fringe (about 3.4–3.8 × as long as wide excluding fringe); costa with a broad irregular black streak from base to basal 4/5, dilated in middle reaching almost 1/2 across wing; subapical with a distinct gold-yellowish strigula; a narrow and nearly straight black streak from dorsum beyond middle to apex, separating creamy-white and gold-yellow areas. Hindwing brownish gray, 1.8–2.0 × as long as wide including fringe (3.1–3.3 × as long as wide excluding fringe). Abdomen. Male genitalia ( Fig. 3 B: left; also see Huang et al. 2007: fig. 4) with uncus lobes widely separated, elongate triangular, about 0.8 × length of valva, apex narrow and pointed, gradually curved ventrally. Saccus elongate, slightly longer than length of valva, widened and flattened posteriorly. Valva simple, elongate-spatulate, narrow throughout, with apex rounded. Phallus nearly straight, cylindrical, stout, about 1.2 × length of valva; apex slightly curved ventrally; vesica with cornuti consisting of a mass of minute spines.

Female. Very similar to male. Female genitalia ( Fig. 3 B: right; also see Huang et al. 2007: fig. 5) with corpus bursae large, bearing a pair of large sword-shaped signa. The entire corpus bursae almost equal in length to apophysis anterioris.

Type material. Holotype (in SCAU), male, CHINA: Guangdong, Shaoguan, Nanling National Nature Reserve, Xiaohuangshan, 1300 m altitude, 11.VI.2005, light trapping, leg. G.H. Huang, L.S. Chen and M. Wang. Paratypes (in OPU and BMNH), 2 males, same data as holotype; 1 male, 2 females, Xiangsikeng, 1360 m altitude, 12.VI.2005, other data same as holotype; 2 males, Nanling National Nature Reserve, 31.V.–6.VI.2006, light trapping, leg. L.S. Chen.

Other material examined (in HUNAU). 4 males, CHINA: Guangdong, Shaoguan, Nanling National Nature Reserve, Xiaohuangshan, 1300 m altitude, 22.VI.2008, light trapping, leg. G.H. Huang.

Bionomics. Seasonal occurrence: May to June, with host unknown.

Distribution. China. Known only from the type locality in southern China.

Remarks. Most Tineovertex species are day-fliers, but we obtained this species only by light trapping. More surveys are necessary to understand the behavioral ecology of this species.
