Tinea melanochrysa Meyrick 1911: 120 (type locality: Khasi Hills, NE India).

Tineovertex melanochryseus: Moriuti 1982: 167 ; Davis 1992: 63.

Tineovertex melanochrysa: Robinson & Tuck 1996: 10 ; Wang et al. 2000: 34; Huang et al. 2007: 39 ; Huang et al. 2008: 261.

Diagnosis. This species can be distinguished from other Tineovertex by the following characters: uncus slender, long; saccus elongate-triangular; and valva elongate-spatulate, slightly curved dorsally.

Description. Forewing length 5.5–6.0 mm in male, 6.0– 6.5 mm in female; antenna length 6.0– 6.5 mm in male, 6.5–7.0 mm in female ( Figs. 1 A–C).

Male. Head. Vertex and frons black. Thorax. Dorsum and tegula black with posterior portions yellowish white. Forewing with apex and termen black, about 2.5–2.9 × as long as wide including fringe (about 3.3–3.4 × 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; apex with one distinct yellowish white costal strigula. Hindwing pale brown, 1.9–2.0 × as long as wide including fringe (3.4–3.7 × as long as wide excluding fringe). Abdomen. Male genitalia ( Fig. 3 A) with uncus lobes widely separated, slender, about 0.5 × length of valva, with apex narrow and pointed, gradually curved ventrally. Saccus elongate triangular, about 0.8 × length of valva. Valva elongate-spatulate, narrow throughout, with apex rounded, slightly curved dorsally. Phallus basally stout with digitate apex, slightly curved ventrally, about 1.1 × length of valva; vesica with cornuti consisting of a mass of minute spines.

Female. Very similar to male. Female genitalia (see Moriuti, 1982: plate 248-6) with corpus bursae bearing a pair of thorn-shaped signa.

Bionomics. Seasonal occurrence: May to December. The female inserts eggs into the living tissue of the fern Blechnum nipponicum (Kunze) Makino (Blechnaceae) , and the larvae feed on dead plant material on the ground after making a portable case (Huang et al. 2008).

Distribution. Japan, China ( Taiwan), India.

Remarks. Huang et al. (2008) described the biology, including oviposition behavior and feeding habits of the early stages based on material from Japan.
