Mujie Qi & Xiaofei Yang, slide No. YS19323. Diagnosis. This species is similar to H. stenopteryx Wu, 2005 in the male genitalia by sharing a valva that is narrowed distally and rounded apically, but it can be distinguished from the latter by the nearly straight costal bar and the sub-crescent cornuti of the aedeagus in the male genitalia; whereas in H. stenopteryx , the costal bar is angled and the cornuti are sagittate ( Wu 2005: 270 , Fig. 3 ).

H. miscogana , slide No. YS19159; 20. H . rotundisigna sp. nov. , paratype, slide No. YS19404. Scales=0.5 mm Description. Adult ( Figs. 4 , 8 ) wingspan 13.5‒16.5 mm. Head dark brown. Antenna pale orange. Labial palpus pale orange except dark brown ventrally on third segment; second segment thickened; third segment slender, as long as second segment. Thorax and tegula dark brown. Forewing with costal margin slightly arched, apex obtuse, termen shallowly concave; dark brown, mixed with brownish yellow; fringe dark brown; basal line orange white; all veins free except R 4 and R 5 stalked for about 3/5 length. Hindwing pale brownish yellow, with a bundle of long, fluffy hairs at base; fringe yellowish brown; basal line orange white; vein M 3 stalked with CuA 1 for about 1/5 length. Fore- and midlegs orange white, mixed with dark brown scales on ventral surface; hindleg pale orange on inner surface, mixed with dark brown scales on outer surface, tibia roughly scaled. Male genitalia ( Fig. 12 ). Uncus lobe transversely elliptical, with a small notch at middle on posterior margin, setose posteriorly, with a narrow V-shaped sclerite anteriorly. Gnathos with lateral arms fused medially and trian- gularly produced posteriorly; median process broad at base, tapered to apex, curved ventrad at distal 1/4. Costal bar nearly straight, narrow basally, widened to cucullus. Valva broad basally, slightly narrowed to cucullus; cucullus slightly narrowed to rounded apex, setose on ventral 2/3, with a densely setose, sub-triangular process at ventrobasal corner and a row of short, strong setae from basal 1/3 to apex above ventral margin; sacculus narrowly banded, reaching cucullus, with a cluster of long setae medially. Juxta sub-quadrate; posterior margin concave at middle, with a large sub-rectangular process posterolaterally, with erect, sub-triangular sclerite along each side of concavity; anterior margin triangularly produced medially. Vinculum roundly produced anteriorly. Aedeagus nearly as long as valva, slightly curved, basal 2/5 narrow, dilated medially, slightly narrowed to apex; cornuti consisting of three subcrescent, dorsally serrate sclerites, located in distal 2/3 of aedeagus. Seventh sternite ( Fig. 16 ). Seventh sternite transversely banded, wider than long, anterior margin slightly convex; anterolateral and posterolateral ribs represented by short, sub-triangular processes. Female genitalia ( Fig. 20 ). Eighth sternite shallowly concave at middle on posterior margin. Apophyses posteriores about twice length of apophyses anteriores. Antrum funnel-shaped, its ventral surface with a spinulate semicircular sclerite. Ductus bursae nearly as long as corpus bursae, wrinkled, anterior half dilated; ductus seminalis anterior to middle of ductus bursae, as broad as corpus bursae. Corpus bursae elliptical; signum rounded, located medially, with a horizontal ridge at middle. Distribution. China ( Xizang [ Tibet ]). Etymology. The specific epithet is derived from the Latin rotund- and signum , referring to the round signum of the corpus bursae in the female genitalia.
