Type specimen. Holotype: ♂, THAILAND. Nakhon Nayok Prov., Khao Yai N.P., 14 o 23ʹ56ʺN, 101 o 22ʹ16ʺE, alt. 786 m; 10 Sep 2010; Pinkaew et al. leg.; np4798 (genitalia slide NP1514); KKIC.

Paratype: 1♂, THAILAND. Nakhon Ratchasima Prov., Khao Yai N.P., 14 o 25ʹ55ʺN, 101 o 26ʹ37ʺE, alt. 791 m, 11 Nov 2009; Pinkaew et al. leg.; np3190 (♂, genitalia slide NP1258); KKIC .

Diagnosis. Hiroshiinoueana partita sp. nov. is similar to H. wuzhishanica . It can be distinguished from the latter species by upperside of hind wing is light brown, and dark greyish brown hair pencil on the inner side of hind tibia, whereas H. wuzhishanica has pale greyish brown on the upperside of hindwing, and black hair pencils on the inner side of hind tibia. In male genitalia, H. partita sp. nov. have subtriangular pointing downward uncus, spines on the large lobe of sacculus are separated into two groups, neck is distinct, and smaller size of a tuft of long bristles is located ventromedially of sacculus, whereas H. wuzhishanica has small semicircular pointing upward uncus, spines on the large lobe of sacculus are not separated, neck is indistinct in left valva, and larger size of a tuft of long bristles is located beyond ventromedially of sacculus.

Description. Head ( Fig. 6 ): Lower frons light brown, upper frons and vertex brown mixed with light brown; labial palpi porrect, first segment light brown, second segment long, dilated to apex, basal 2/3 brown, apical 1/3 light brown, third segment light brown; antenna light brown, reaching middle of forewing. Pronotal collar and tegulae brown with some metallic silvery scales when angled to light; mesonotum light brown mixed with brown, posterior crest mostly loss; hind tibia light brown, basal half of inner side with a tuft of brown hair pencils, originated beyond base of tibia ( Fig. 8 ). Forewing broad rectangular, wingsapn 12.7–13.3 mm in male ( Fig. 5 ) (n = 2); costal margin evenly curve; termen rather round; costal strigulae indistinct, ground color brown with diffuse metallic silvery spots throughout; underside light greyish brown. Hindwing light brown, anal margin with long marginal fold ( Fig. 7 ); underside light greyish brown with thickened, folded anal margin.

Abdomen: Tergum II with two small pits on anterolateral corners ( Fig. 20 ), tergum VIII with enlarged posterior margin, slightly concaved medially ( Fig. 21 ). Male genitalia ( Figs. 15–17 ). Tegumen widened basal half, narrower rounded dome-shaped apical half, dorsolateral corners folded, densely setose sockets; uncus small, subtriangular hairy lobe pointing ventrally ( Fig. 16 ); socii moderately long plate-like, densely setose; gnathos moderately sclerotized, narrowed band, arising from midlength of tegumen, extending inwardly then abruptly bent upward; vinculum moderately wide; juxta subtrapezoid; caulis long, apical 2/3 enlarged; anellus wide, sclerotized, surrounding phallus, dorsal reach to apical 3/4 of phallus length; phallus rather short, slightly curve horn-shaped, pointed apex, cornuti absent; valvae symmetry, longitudinal folded, basal excavation with moderately dense, short setae on margin reaching sacculus basally; sacculus with a tuft of long bristles ventromedially, with a large oblique spiny lobe medially, suboval-shaped, protruding inwardly narrowed to phallus, dorsal margin folded, slightly widened to base of lobe and adjacent to base of cucullus, margined with row of dense, short and strong spines pointing oblique ventrally, inner margin combined with basal excavation edge, concaved apicomedially, outer margin round, pendant over ventromedially of sacculus, with aciculate patch along margin lateromedially, with large concave beneath lobe, wrinkled surface, lobe mostly covered with a large, oval-shaped patch of short and strong spines, distinctly split apically from row of spines on dorsal edge, pointing obliquely upward to phallus ( Fig. 17 ); neck distinct, moderately dense setae ventrally; cucullus smaller than sacculus, widened crescent-shaped, densely setose ventral half to apex.

Distribution. Thailand

Etymology. The specific epithet ( partita = separate) refers to separated group of spines on basal large lobe of valvae.

Remarks. Wing pattern of Hiroshiinoueana partita sp. nov. in both type specimens are rather rubbed especially ground color and fascia but mottle metallic blue spots throughout the forewing are remained.
