03AB87ECA052B51039FE139E65A4FB8A.taxon	diagnosis	Diagnosis. Species of the genus can be recognized by the following external characters: (1) the ground color of forewing is creamy white or sordid white, with dark brown or pale brown markings or a large ochreous patch, and two dark discoidal spots or streaks; (2) the hindwing is pale gray, except for some Australian species having distinct, dark terminal band. In the male genitalia (for the Oriental species), the valva is very diverse, and the aedeagus is slender, strongly curved, with a vesica bearing irregular cornuti. In the female genitalia, the corpus bursae bears a signum in most species (Černý & Pinratana 2009; Bucsek 2012, 2014; Bayarsaikhan et al. 2021).	en	Bayarsaikhan, Ulziijargal, Bucsek, Karol, Cha, Yeong-Bin, Le, Xuanvi, Kwon, Hyung Wook, Bae, Yang-Seop (2022): A new Halone Walker (Lepidoptera, Erebidae, Arctiinae, Lithosiini) from Vietnam with establishing of a new combination.

03AB87ECA052B51239FE16AF64C1FF21.taxon	diagnosis	Diagnosis. Halone arcuata sp. nov. differs from other congeners by its dark brown longitudinal streak (the antemedial and the disco-cellular spots are almost connected) in the discal area of the forewing. The male genitalia of the new species is similar to those of Halone victorai Bucsek, 2014, H. solitus Bucsek, 2014 and H. hollowayi Bayarsaikhan & Bae, 2019 due to the irregularly projected tegumen, the well-developed saccular process as length as elongated, membranous cucculus. However, H. arcuata sp. nov. differs from the allied species in having a roundly arch-shaped projection of the tegumen and a dentate, strongly arcuate and sclerotized saccular process, with an acuminate apex, while in H. viktorai (illustrated by Bucsek 2014: gen. MalS 25; present paper fig. 6), the subapical projection of the tegumen is slender, almost straight and spine-shaped, and the saccular process is slender, weakly tapering, entire, with a rounded apex. In H. solitus (illustrated by Bucsek 2014: gen. MalS 26; present paper fig. 7), the apical projection of the tegumen is broad and rectangular, and the slender saccular process is entire, slender and apically rounded. In H. hollowayi (illustrated by Bae & Bayarsaikhan 2019: fig. 5; present paper fig. 8), the apical projection of the tegumen is strongly tapering, curved, the saccular process is more stout than in H. arcuata sp. nov., entire and has an irregularly rectangular apex. In the female genitalia, the following features clearly separate the new species from all the other known females of genus Halone: (1) the postvaginalis plate is sclerotized, “ bow tie ” - shaped and densely serrulate; (2) the anterior section of the antrum is broadly rounded, sclerotized, with weakly waved edge; (3) the lamella antevaginalis is horizontally elongate, arch-shaped and sclerotized.	en	Bayarsaikhan, Ulziijargal, Bucsek, Karol, Cha, Yeong-Bin, Le, Xuanvi, Kwon, Hyung Wook, Bae, Yang-Seop (2022): A new Halone Walker (Lepidoptera, Erebidae, Arctiinae, Lithosiini) from Vietnam with establishing of a new combination.

03AB87ECA050B51539FE14FE6431FC11.taxon	discussion	Remarks. This species was described from Thailand as a member of the genus Eugoa by Černý (2009), without illustration and description of its genitalia. The examination of the genitalia structures of this species by the second author led to the conclusion that it belongs to the genus Halone Walker, 1854, and is closely similar to Halone solitus Bucsek, 2014 (illustrated by Bucsek 2014: gen. fig. MalS 26 )). Thus, here we establish a new combination: Halone bucseki (Černý, 2009), comb. nov. Original description of adult by Černý (2009). (Figs. 11 a, 11 b). Wingspan 11 ˗ 13 mm in males, 13 ˗ 15 mm in females. Head and antenna pale brown. Thorax and legs grayish pale brown. Forewing pale brown, covered with dark scales; dark antemedial line angled in cell; a dark disco cellular spot rounded; dark postmedial line indistinct; terminal series of spots dark; and lines of forewing particularly reduced sometimes. Hindwing suffused with gray. Abdomen grayish pale brown.	en	Bayarsaikhan, Ulziijargal, Bucsek, Karol, Cha, Yeong-Bin, Le, Xuanvi, Kwon, Hyung Wook, Bae, Yang-Seop (2022): A new Halone Walker (Lepidoptera, Erebidae, Arctiinae, Lithosiini) from Vietnam with establishing of a new combination.

03AB87ECA050B51539FE14FE6431FC11.taxon	description	Description of genitalia. Male genitalia (Fig. 12). Uncus stout, with angular apex. Tegumen sclerotized, roundly shouldered posteriorly, with two strongly sclerotized medial spurs. Valva wide basally, slightly taperered to 3 / 4 and somewhat dilated in distal quarter. Apical process flat with blunt hips, saccular weakly covered with setae, distal plain. Distal costal lobe of valva pronounced. The basal costal process creates a small triangular ˗ shaped vertex. Juxta weakly sclerotized, arch ˗ shaped. Vinculum broadly “ U ” ˗ shaped. Aedeagus stout, distal half strongly sclerotized and curved, with two apical processes, and vesica with a large (almost half size of aedeagus), tapering cornutus and scobinated. Female genitalia (Fig. 13). Papillae anales weakly covered with setae. Apophysis posterioris and anterioris slender, same sized. Ostium sclerotized, arched. Ductus bursae tubular, membranous. Corpus bursae globular, membranous, with a weakly waved, sclerotized short band covered by the short, stout spines.	en	Bayarsaikhan, Ulziijargal, Bucsek, Karol, Cha, Yeong-Bin, Le, Xuanvi, Kwon, Hyung Wook, Bae, Yang-Seop (2022): A new Halone Walker (Lepidoptera, Erebidae, Arctiinae, Lithosiini) from Vietnam with establishing of a new combination.
