( Figs. 1, 4 )

Diagnosis. This species is similar to H. aritai (Kawabe) in appearance, but can be separated by forewing with basal patch, a small triangular brown patch and inverse triangular ocelloid patch; uncus nearly trapeziform. While in H. aritai all patches are inconspicuous except rectangular ocelloid patch and uncus is mound-like.

Description. Adult ( Fig. 1 ). Head: Vertex with brown scales, frons with white scales. Antenna brown. Labial palpus brown, inner side white, second segment dilated towards apex, third segment grey, porrect. Thorax: Thorax and tegula with basal half brown, apical half grey. Forewing length 8.0 mm. Forewing with ground color leaden grey; basal patch occupying basal 1/3 of forewing, indicated by several grey streaks, originating from costal 1/4, extending outwardly near the middle of wing, then turning inwardly to 1/3 of dorsum, transverse dark grey streak on the middle of wing, dorsum with a small triangular brown patch before ocelloid patch, ocelloid patch inverse triangular, grey, with five parallel short brown streaks near outer edge; costa brown, with five pairs of white strigulae from apex to costal half; cilia light brown. Hindwing and cilia grey. Abdomen: Male genitalia ( Fig. 4 ). Tegumen broad; uncus broad, nearly trapeziform, less hairy; socius hairy, relatively long, drooping, apically round; gnathos weakly sclerotized; valva with neck distinct; basal opening relatively small; sacculus slightly dilated towards its end, setose around basal opening, with a very weak lobe on ventral edge of basal opening, sacculus angle nearly right-angled; cucullus somewhat boot-shaped, setose, with marginal spines; phallus relatively long, cone-shaped; vesica with a bunch of cornuti.

Male scent organs. Forewing with a brown narrow costal fold reaching before half of costa, with relatively long scales apically; circular pocket at base of 1A+2A vein in forewing absent. Hindwing with a tuft of hair-like scales at the base of cell on the upper surface.

Holotype. ♂, CHINA: Guangxi Zhuang Autonomous Region, Jinxiu County, Silver Fir Protection Station , alt. 700 m, 27 April 2008, coll. H. Zhen & L. Zhang, genitalia slide no. ZAH16036.

Distribution. China (Guangxi).

Etymology. The specific name is derived from the Latin trapezius = trapeziform, indicating the shape of uncus.
