Eugoa bucseki Černý in Černý & Pinratana, 2009, Moths of Thailand, vol. 6: 27, pl. 4: 53. TL: SW Thailand (Nakhon Si Thammarat, Kao Luang NP).
Holotype. 1 ♀, SW Thailand, Nakhon Si Thammarat, Khao Luang NP, Nopphitam env. 70m, 8˚44,043′N, 99˚41,450′E, 6.XII.2007 (leg. K. Černý).
Material examined (Paratypes). 1 ♂, SW Thailand, Nakhon Si Thammarat, Khao Luang region, Nopphitam env., 276m, 8˚47,447′N, 99˚43,514′E, 7.˗9.XII.2007 (leg. K. Černý), 1 ♀, SW Thailand, Ranong-prov., Ranong, 380m, 10˚01′32″N, 98˚40′13″E, 3.˗4.XII.2005 (leg. K. Černý).
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. MalS26)). Thus, here we establish a new combination: Halone bucseki (Černý, 2009), comb. nov.
Original description of adult by Černý (2009). (Figs. 11a, 11b). 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.
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.
Distribution. Thailand (Černý & Pinratana, 2009).
