Hiroshia albinigra László, Ronkay & Ronkay, 2001 , Acta Zoologica Academiae Scientiarum Hungaricae 47(1): 60, figs 21–22, 63, 71; László, Ronkay & Ronkay 2007, Esperiana 13: 216, pl. 24, figs 4–6, 168.

Material. 1 male, China, Yunnan, Tiger Leaping Gorge, 2050 m, 04. July. 2013, leg. WANG Min, ZHANG Hailing, WANG Yu.

Diagnosis. Hiroshia albinigra differs from the externally very similar relative, H. nanlingana sp. n, by its more clear wing pattern and finer black crosslines with small curve. The male genitalia are conspicuously different from those of the new species by the broader tegumen and the valval transtillae with considerably smaller and weaker sclerotized spine.

Description. Male ( Fig. 2 A) and Female: Wingspan 46–51 mm, length of forewing 22–25mm, rather large species with strong body and broader forewings having pointed apex. Eyes large and naked, palpi porrect, third joint stretch out the head. Antenna lamellate, laterally flattened, brown or dark brown, frons broad with large tufts. Collar distinct and well-developed, metathorax with big tufts and long hairs. Abdomen rather thick with blackish tufts. Forewing broad, ground color usually dark brown with rather clearly black and white pattern. Postmedial area, white apical macula with broader extension, postmedial and subterminal lines rather distinct, anal macula black. Medial area with dark red pattern, more sinuous crosslines, reniform macula large and unclear while orbicular macula small and clear. Antemedial area with rather obvious, large white pattern, the basal area with projecting white tufts. Hindwing dark brown with an inconspicuous gray zone. The external appearance of female similar to male.

Male genitalia ( Fig. 2 B): Uncus long with blunt end, socii short with smoothly, broader basal plate. Tegumen short and broad, fultura superior reversed T-shaped. Broad quadrangular valva sclerotized, with almost parallel costal and ventral margins, sclerotized appendices of transtilla with two upheavals, which have individual differences, subcostal process long acute, long spine situated in the middle area of valva, sacculus inflated, sclerotized, with short spinous extension. Fultura inferior triangular, with sclerotized extension area. Vinculum broadly U-shaped. Aedeagus medium-long, thick, vesica armed with a field of strong cornuti, cornuti with thick spines and denticles, hook-shaped process of carina.

Female genitalia: Papillae anales light sclerotized, apophyses posteriores long, 8th segment rather broad, Ushaped, heavily sclerotized, infundibulate ostium bursae rather large, sclerotized. Ductus bursae membranous, short. Corpus bursae with short, acute signum.

Distribution. Vietnam (Fan-si-pan Mts); China (Yunnan).
