The genus is very special in its external characters. It can be easily distinguished from other genera of the subfamily by having a much brighter and conspicuous wing pattern. The valva usually has spines or sclerotized plate medially located in the male genitalia and the oval or rounded corpus bursae have the rounded signa in the female genitalia, which are same as in the genus Stericta. But it differs from the latter by the shapes of valva and juxta. In general, the wings have an orange to yellow postmedial fascia with dark brown edges. In the male genitalia, the uncus usually has long or short spines laterally located, the sacculus always has two sclerotized processes medially located, and the valva usually has a variously-shaped sclerotized plate in the central area distal to the saccular processes.

Head covered with dense scales; labial and maxillary palpi upturned; antennae filiform, male with a scape extension covered with dense scales. Both wings with similar patterns, fasciae indistinct except postmedial fascia, postmedial fasciae conspicuous, and smooth at border.

Uncus broad, gnathos various. Valva broad, and outer margin usually truncated; costa sclerotized; sacculus well developed, often with hook-like or spine-like processes, usually extending backward to base of valva. Phallus slender, slightly curved.

Ovipositor covered with dense setae. Sterigma associated with the ostium bursae appears to be sclerotized. The papillae analis are not extruded and are located within the 8^th segment; the sterigma is lightly sclerotized and the lamella postvaginalis is variously sclerotized. Apophysis anterior nearly same length or longer than apophysis posterior. Ductus bursae slender, usually membranous. Corpus bursae elliptic or rounded, usually with two rounded or oval-shaped signa consisting of many minute spines.

The new species is very similar to L. haraldusalis in wing pattern, but the wing color of the new species is darker than the latter. In the male genitalia, it can be distinguished from the latter by the narrower valva, having two lateral spines in the gnathos, and lacking spines in the uncus.

The specific name is derived from Latin angustus (= narrow) in accordance with its narrow valva.

The species is different from congeners by paler scales on the forewing, the tip of the gnathos without denticulation, and the juxta swollen, the apex bifurcated with two pointed processes.

Yamanaka (2000) reported this species in Nepal. However, according to the related literature, the genitalia are quite different from those of L. ficki (Christoph, 1881) provided by Janse (1931). Meanwhile, their structure of the male genitalia matches the figure of L. haraldusalis (Walker, 1859) provided by Marumo (1942). Therefore, his reported species actually is L. haraldusalis (Walker, 1859) rather than L. ficki (Christoph, 1881).

The new species is similar to L. longifundamena sp. n. Both species are different from other congeners by the straight postmedial fascia on the forewing; however, L. longifundamena sp. n. has the valva slightly constricted from the middle to the apex, the sacculus with the inner processes at middle more slender, and the apex of the juxta bifurcated with two strongly sclerotized slender arms.

Adult. Forewing length 9.5–10.5mm (n = 4). Head yellow; labial palpus upturned, mixed with yellow and black scales; maxillary palpus pale yellow; antenna pale brown, scape extension black, mixed with golden scales in male. Thorax mixed with blackish-brown and a small number of yellow scales. Forewing covered with brown, yellow, black and pink scales; postmedial fascia straight, pale yellow with brown edges, outer area covered with fuscous and dark pink scales; cilia brown. Hindwing with similar pattern to forewing, but more brown scales than forewing in central area, and outer area covered with pink scales.

Male genitalia (Fig. 15). Uncus broad, densely covered with setae, two spine-like processes at base laterally. Gnathos narrower and more sclerotized than uncus. Valva slightly broader from base to apex, apex rounded; costa slightly sclerotized, apex swollen; sacculus with two processes in middle, the inner one spine-like, the outer one thorn-like, a thin sclerotized plate from sacculus to center of valva. Juxta peltate and bifurcated, apex pointed. Phallus curving slightly, with a crescent-shaped cornutus at apex.

Female genitalia (Fig. 25). Ovipositor slightly narrow, suffused with setae. Apophysis anterioris longer than apophysis posterioris. Ductus bursae slender, membranous. Corpus bursae round, with two signa, nearly oval.

The specific name is derived from Latin gilvas (= pale yellow), in accordance with the yellow postmedial fascia of the new species.

The species can be distinguished from other species of the genus by its specific gnathos. In this species, the gnathos is broader and more sclerotized than that in other species and it has a serrated apex that is located medially.

Li and Ren (2008) reported this species in Henan; however, the genitalia are quite different from those of L. haraldusalis (Walker, 1859) provided by Marumo (1942). Meanwhile, their figure of the adult matches the original figure of L. insulsalis (Lederer, 1863). Thus, their description actually refers to L. insulsalis (Lederer, 1863) rather than L. haraldusalis (Walker, 1859). In addition, the species was wrongly recognized as L. ficki by Yamanaka (2000). We correct their identification here.

The species differs from other species by rustier colored scales on the wings, the uncus with two extremely elongated arms laterally located, and the slender processes of the sacculus about twice as long as in other species.

The species was wrongly recognized as L. haraldusalis (Walker, 1859) by Li and Ren (2008). We correct their identification here.

The name is derived from Latin longus (= long) and fundamen (= base), in accordance with the juxta and two long spines at base.

This new species is very similar to L. haraldusalis, but the basal area on the forewing is slightly paler than the latter. In the male genitalia, the gnathos has three spines at the apex in the new species while the gnathos has a serrated apex in L. haraldusalis. Furthermore, the sclerotized plate on the valva strongly extends toward the outer margin in the new species.

China (Gansu, Jiangxi, Fujian, Taiwan, Guangdong, Hainan, Sichuan, Yunnan), Philippines.

The species is reported in China for the first time.

This species is hard to distinguish by its external characters. It differs from other species by the sacculus with a single process in the middle, while the sacculus usually has two processes in other species. Furthermore, the sclerotized plate on the valva is twice or three times as broad as others.

Adults. Forewing length 11.0–12.5mm (n = 6). Head blackish-brown; labial palpus upturned, mixed with fuscous and black scales, stronger in male; maxillary palpus pale yellow; antenna brown, scape extension black, mixed with fuscous scales in male. Thorax mixed with brown and fuscous scales. Forewing covered with brown, black and pink scales; base mixed with yellow and black scales; costal margin yellow; postmedial fascia orange with brown edges, outer area covered with pink and fuscous scales; cilia grey. Hindwing with same pattern as forewing.

Male genitalia (Fig. 21). Uncus broad, suffused with dense setae. Gnathos broad, base extended to two strongly sclerotized spine-like processes laterally located, apex with three spines. Valva nearly the same width from base to apex; costa extruded the apex of valva; sacculus with a single spine-like process in middle; a well-developed sclerotized broad plate from sacculus to centre of valva. Juxta bifurcated with two pointed plates at apex. Phallus slender, slightly curved.

Female genitalia (Fig. 31). Ovipositor broad, densely suffused with setae. Apophysis anterioris longer than apophysis posterioris. Ductus bursae slender, membranous. Corpus bursae round, with two rounded signa, slightly sclerotized.
