Lasiochira camaropa Meyrick, 1931, by monotypy.

Holotype : ♂; China: Hainan province, Wuzhishan City, Wuzhishan National Nature Reserve; alt. 650 m; 18°54'36"N, 109°40'48"E; 10 May 2018; Zhengyong Wang leg.; YC00025. Paratypes: 1 ♂, 3 ♀♀; same locality as holotype; alt. 650 m; 18°54'36"N, 109°40'48"E; 10–15 May 2018; Zhengyong Wang leg.; YC00026 ♂, YC00022 ♀, YC00023 ♀, YAH19072 ♀.

Lasiochira wuzhishanensis Yin, sp. nov. can be distinguished from its congeners by the following two character states: forewing ocherous brown in ground color (Fig. 1); phallus with seven cornuti (Fig. 4, arrows).

Figures 1–3. 

Adults of Lasiochira species 1 L. wuzhishanensis Yin, sp. nov., paratype, female, gen. slide no. YAH19072 2 L. jianfengensis Yin, Wang and Park, female, gen. slide no. YC00028 3 L. pallidiptera Yin, Wang and Park, male, gen. slide no. YAH18154. Scale bars: 2.00 mm.

Head: Vertex and front white, tinged with pale ocherous yellow on cervical area; labial palpi white, first segment with dark brown scales dorsally, second segment somewhat tinged with pale ocherous brown, denser ventrally, third segment with broad pale ocherous brown ring at distal 1/4; antenna with scape white, covered with pale ocherous yellow scales on dorsal surface, pecten pale yellow, flagellum pale ocherous yellow, ringed with white; proboscis white.

Thorax: Tegula and mesonotum white, with three transverse pale ocherous brown bands; legs pale yellowish white, tibiae and tarsi pale ocherous brown on outer surface and pale ocherous brown and pale yellowish white on inner surface. Forewing (Fig. 1): length 5.5–7.0 mm (N = 5), about 3.3 × as long as wide, ocherous brown, slightly paler between CuP and dorsum; an N-shaped pinkish pattern running from basal 2/5 of costa diagonally outward to posterior angle of cell, obliquely to subapical part of costa, enlarged on costal margin, and diagonally narrowed to ventroapical part of termen; innermost stripe edged with two erect scale tufts, tufts black or ocherous brown on inner margin, angle between innermost and middle stripes diffused with blackish brown scales, and anteriorly with an erect pale yellowish white scale tuft, middle and outmost stripes both edged with erect scale tufts, tufts black or ocherous brown on outer margins; CuP with an erect scale tuft near distal 1/3; cilia with basal 3/5 pale ocherous brown, distal 2/5 pinkish white, edged with dark brown; ventral surface grayish brown. Hindwing (Fig. 1): dark gray; cilia yellowish gray.

Male genitalia (Fig. 4): Uncus broad at base, gradually narrowed to about 1/2, apical half parallel bilaterally, apex rounded; gnathos obtriangular, with minute granules on apical half; tegumen with nearly trapezoid posterior margins fused with uncus, anterior margin deeply emarginate; valva short and broad, sub-rectangular, heavily setose on triangular area apically; costa nearly straight; ventral margin triangularly concave inward beyond end of sacculus; sacculus narrow, slightly arched ventrally, distally with a triangular process directing downward; vinculum narrowly banded; saccus short, triangular, apex bluntly rounded; juxta obtrapezoidal, posterior margin straight, anterior margin concave mesially, lateral margins deeply emarginate at middle, forming two opposable triangular arms; phallus stout, distal 1/4 protuberant, extending to a sharp point; vesica with six irregularly-shaped, plate-like cornuti, and one small cornutus (Fig. 4, arrows).

Female genitalia (Fig. 6a): Papillae anales setose, broadly rounded posteriorly; apophyses posteriores about 2.5 times length of apophyses anteriores; eighth sternite with posterior margin straight, setose on posterior half, darkly pigmented mesolaterally, paler mesolongitudinally; antrum wide, membranous; ductus bursae narrow and sclerotized posteriorly, elongate, with undulating internal sclerotization anteriorly, bearing inception of ductus seminalis on anterior part; ductus bursae subspherical, with a spiculate inner wall; signum a transverse, dentate band, with a posteriorly projecting semicircular lobe.

Lasiochira wuzhishanensis Yin, sp. nov. is very similar in wing pattern to L. jianfengensis Yin, Wang and Park (Figs 1, 2), but differs by having juxta with posterior margin straight (Fig. 4); phallus with seven cornuti (Fig. 4, arrows); and corpus bursae small, nearly spherical in shape (Fig. 6a). Lasiochira jianfengensis has juxta with posterior margin emarginate mesially (Fig. 5); phallus with six cornuti (Fig. 5, arrows); and corpus bursae ovate in shape and larger (Fig. 7a).
