(Figs. 2, 5)
Diagnosis. This species is close to H. simplex Zhang & Li in appearance, but can be distinguished by the following characters: male forewing without a circular pocket at base of 1A+2A vein, mound-like uncus and oblong cucullus, length beyond three times of width. In H. simplex male forewing bears a circular pocket at base of 1A+2A vein, uncus is produced into two weak processes apically and cucullus is irregularly oblong, length shorter than three times of width.
This species is also similar to H. axiotima (Meyrick) on characters of male genitalia but can be discriminated by forewing without distinct patches except ocelloid patch, male forewing without a circular pocket at base of 1A+2A vein, tegumen without a pair of lobes dorsolaterally and sacculus without lobe on the ventral edge of basal opening in the male genitalia. While in H. axiotima, forewing bears a wide sinuate cream-white streak touching costal triangular cream-white patch apically, male forewing bears a circular pocket at base of 1A+2A vein, a pair of large ear-like lobes are on tegumen dorsolaterally and sacculus has a mound-like lobe on the ventral edge of basal opening in the male genitalia.
Description. Adult (Fig. 2). Head: Vertex and frons fulvous. Antenna dark brown. Labial palpus fulvous, second segment slightly dilated towards apex, third segment minute, porrect. Thorax: Thorax and tegula leaden grey. Forewing length 6.0 mm. Forewing with ground color leaden grey, darker along costa, with a thin sinuate white streak along termen, ocelloid patch nearly rectangular, light grey, with black dots along inner and outer side; costa with five pairs of silvery strigulae from apex to 1/3 of costa, confluent downward and extending to termen; cilia fulvous on termen and grey on tornus. Hindwing grey, cilia fulvous on termen and grey on tornus. Foreleg and midleg brown, hindleg grey, tarsus with brown rings. Abdomen: Male genitalia (Fig. 5). Tegumen broad. Uncus moundlike, hairless; socius oblong, drooping, hairy, with round end; gnathos weakly sclerotized; valva deeply constricted, with distinct neck; sacculus broad, with some setae on the posterior edge of basal opening, sacculus angle round; cucullus oblong, outer margin concave, length beyond three times of width, setose, with marginal spines, rounded dorsally and ventrally; phallus thick and short, tubular; cornuti numerous, spiculate.
Male scent organs. Forewing with a dark brown costal fold reaching 1/3 of costa; 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 side.
Holotype. ♂, CHINA: Yunnan Province, Pu’er City, Taiyanghe Natural Forest Park, Yuyingtang, alt. 1,450 m, 7 April 2015, coll. K. Teng, genitalia slide no. ZAH16047.
Etymology. The specific name is derived from the Latin simil - (= similar) and simplex (= simple), indicating this species is similar to H. simplex.
