Diagnosis. Hiroshiinoueana inequivalva differs from the two previously described species by the narrow and elongate dorso-basal spiny lobe of valva in the male genitalia, which is broad and rounded in the other two species. The new species also can be separated easily from H. gangweonensis by the bristle clusters of the valvae of different size and the cucullus with a rounded dorsal margin; in H. gangweonensis the bristle clusters of the valvae are identical on the right and left sides, and the cucullus is half-moon shaped and its dorsal margin is almost straight. Two additional characters of the male genitalia can be used to distinguish this new species from H. stellifera : the median portion of the gnathos is bilobed in H. inequivalva , whereas the gnathos is a transverse band with a pending process in H. stellifera ; and the cucullus is rounded in this new species, whereas it is triangular in H. stellifera . Differences between this new species and H. wuzhishanica are provided above.

Description. Adult ( Fig. 3 ). Head: Vertex rough scaled, pale brown. Antenna pale brown, dusted with black scales. Labial palpus porrect, pale yellowish brown; median segment expanded ventrally, terminal segment pointed.

Thorax: Yellowish brown with pale metallic spots. Hind tibia in male not enlarged. Forewing length 7.0– 7.5 mm; long triangular, costa slightly arched apically, apex blunt; costa with distal 1/4 white; costal strigulae dingy white to pale brown; upperside ground color pale brown with light-blue metallic spots throughout, markings dark brown suffused with pale ochreous, with edges ill-defined; basal and subbasal fascia occupying basal 1/4 of wing; median fascia broad and oblique, proximal edge extending from 2/5 length of costa to mid-dorsum, distal edge reaching tornus; postmedian fascia connected with preterminal and terminal fascia, somewhat crescent shaped, lower part reaching termen between M2 and CuA1; termen white between apex and M2; white scales scattered over area between median fascia and postmedian fascia, forming several small pale dots inside tornus, indistinct in some specimens; fringe dark brown; underside pale brown. Hindwing pale brown except costa white, fringe pale brown, anal fold absent; underside pale brown.

Abdomen: Male genitalia ( Fig. 5 ) with tegumen strongly sclerotized. Uncus and socius weakly sclerotized; uncus reduced; socius drooping, finger-like, with basal part broad, sparsely spined. Gnathos strongly sclerotized, with lateral part very narrow, median portion protruding to two large rounded petal-shaped lobes, naked. Valvae with basal parts strongly sclerotized and distal parts weakly sclerotized; asymmetrical, left valva larger; basal excavation distinct; cucullus with basal part expanding inward to a large rounded lobe bearing rows of spines, most spines directed towards phallus, diminishing in size backward; sacculi asymmetrical; left sacculus larger, with basal part expanded and densely spined, apical part forming a rounded prominence and bearing a thick cluster of long bristles, length of bristles about equal to sacculus; right sacculus smaller, basal part same as left sacculus, distal part small and not expanded, apical bristle cluster adjacent to spined basal part, slender, length about 3/5 times that of left sheaf; cucullus weakly sclerotized, broad, folded longitudinally, with sparse spines, rounded distally. Anellus well sclerotized, broadly surrounding phallus; phallus simple, narrow, without cornuti. Vinculum simple, narrow.

Female genitalia ( Fig. 6 ) with papillae anales elongate. Anterior and posterior apophyses slender, about equal in length. Sterigma ( Fig. 7 ) strongly sclerotized, smooth, deeply invaginated to form a thick tube and expanded medially. Ductus bursae with posterior 1/3 surrounded by sterigma, posterior half sclerotized, and anterior portion membranous; slender, except expanded at middle. Corpus bursae ovoid, granulated; signum ( Fig. 8 ) a large, rounded, scobinate patch with seven elongate teeth radiating from a small central circle and pointing outward.

Molecular characterization. Partial mitochondrial COI gene sequence with GenBank accession number MG983837 for one female paratype, MG983838 for one male paratype.

Etymology. The specific name is derived from the Latin prefix in -, equi - (= equal) and valva, referring to the asymmetrical valvae in the male genitalia.
