Superficially, the new species is very similar to O. captiosana (Falkovitsh, 1960) and O. subtilana (Falkovitsh, 1959). It can be distinguished from the latters by the curved angle of the preterminal fascia in the forewing that is situated near the tornus, whereas in the other two related species the preterminal fascia in forewing is situated near the termen. If compare the male genitalia of the new species with O. captiosana, the uncus of the new species is setose, bifurcated, and narrower. The new species possess a small spinous patch present at the middle of the sacculus. Also, the phallus of the new species is longer, than that of O. captiosana; cornutus is absent in the new species. Description. Male (Figs 1a, 1b). Head: Frons ivory; vertex ivory mixed with dark gray scales. Antenna filiform, covered with dark brown scales. Ocellus present. Labial palpus slightly upcurved and covered by ivory scales with a dark brown line on the outer surface, segment 2 with a dark brown mark, segment 3 exposed at the tip, erect, mixed with dark gray scales. Thorax: Patagium and tegula with yellowish-orange scales. Forewing length 15–18 mm, forewing elongatesubtriangular, broad; costa slightly curved outwards; apex pointed; termen convexly rounded; ground color orangeyellow, costal strigulae weak; basal area with three metallic silver, longitudinal streaks, second streak joined at a nearly right angle from the costal streak, costal streak oblique, extending slightly inward; subbasal fascia with a slightly curved metallic silver cross line, nearer to the median fascia, reticulated; median reticulated fascia with four metallic silver markings in the center of dark ovoid patch consisting of irregular dots and lines; preterminal fascia curved inward, near tornus; terminal fascia less curved than preterminal fascia, metallic silver; cilia ivory and pale dark gray. Hindwing elongate-ovate, pale dark brown, with a darker apical area; apex rather acute; cilia ivory, subbasal line dark brown. Abdomen: ivory and dark brown. Male genitalia (Figs. 4). Uncus narrow, apex bifurcate and with spines on top, setaceous. Socius drooped and setaceous. Gnathos sclerotized partly. Tuba analis shorter than uncus and membranous. Tegumen long-trapezoidal. Valva flattened, broad, not folded at middle. Cucullus narrower than sacculus, apex rounded and setaceous, spined, along ventral margin, in a row on basal costa. Sacculus with a patch of short, small spines on middle of sacculus; short and stout spines grouped on angular part. Phallus about as long as cucullus, split apically into a pair of mittensshaped processes. Female. Unknown. Distribution. Korea (GG, GW, JN). Host plant. Unknown Remarks. This species is very similar to O. captiosana (Falkovitsh, 1960) and O. subtilana (Falkovitsh, 1959), and the three forms a tight species group. Etymology. This specific name is derived from the Latin, “oculatus” meaning “eye-shaped”, referring to ocellus markings on the forewing., Published as part of Kim, Jeong-Nam, Bayarsaikhan, Ulziijargal, Lee, Tak-Gi, Cha, Yeong-Bin, Kim, Hanul, Byun, Bong-Kyu & Bae, Yang-Seop, 2022, A new species of Olethreutes Hübner, 1822 (Lepidoptera, Tortricidae, Olethreutinae) from Korea, pp. 486-492 in Zootaxa 5219 (5) on pages 487-489, DOI: 10.11646/zootaxa.5219.5.6, http://zenodo.org/record/7431406, {"references":["Falkovitsh, M.

Stictane trigonica Bayarsaikhan & Černý, sp. n. (Figs 11, 19, 24) Type materials. HOLOTYPE: 1 ♂, SW Thailand, Chumphon-prov., Pa Toh distr., Ban Lang Tang, 162m, 7.XII.2005 (N9˚46′5″, E98˚46′59″) (leg. K. Černý), Gen. Slide No. INU˗10363 Thailand. PARATYPES (2 ♂, 1 ♀) SW Thailand: 1 ♂, same data as for the holotype; 1 ♂, 1 ♀, Ranong, 543m (N10˚02′1″, E98˚40′17.66″), 7.IV.2013 (leg. K. Černý), Gen. Slide No. INU˗10353 Thailand (Coll. CKC). Diagnosis. The new species has no remarkable external differences from other members of the genus in the antemedial series of three large dark spots (fourth small dark spot presented near tornus in S. trigonica sp. n.), more or less curved dark medial band, 1–3 discoidal dark spots (two dark spots in S. trigonica sp. n., figs 7a, b), and a curved postdiscal series of dark small spots of whitish forewing. According the subapical spine on outer margin of cucullus in male genitalia, the present new species is similar to S. fractilinea (Snellen, 1880), S. muara Holloway, 2001, S. heppneri Bayarsaikhan & Bae, 2019, and S. bayarsaikhanae Bucsek, 2020. But the new species can be distinguished from those similar species by the short (shorter than apex of uncus), roundly stout valva with a short subapical spine on outer margin of cucullus medially, it is above the tip of saccular spine, and aedeagus vesica has an area of thin, diverse sized spines and one large-wrinkled spine. In S. fractilinea, slender valva is longer than apex of uncus, with a short (almost same size to S. trigonica sp. n.) subapical spine on outer margin of cucullus, it is arising immediately near the tip of saccular spine, and aedeagus vesica has a bundle of thin spines and a straight larger one (Kirti et al. 2013: 4, figs 4–7). In S. muara, stout valva is shorter than apex of uncus, with a long (almost four times longer than S. trigonica sp. n.) subapical spine on outer margin of cucullus, it is arising immediately near the tip of saccular spine, and aedeagus vesica with numerous cornuti (Holloway 2001: 418, figs 8d-e). In S. heppneri, stout valva is shorter than apex of uncus, with a long (almost two times longer than S. trigonica sp. n.) subapical spine on outer margin of cucullus, it is above the tip of saccular spine, and aedeagus vesica has two bundles of thin, short spines and a long, slender, strongly waved one (Bayarsaikhan et al. 2019: 260, fig 24a-b). In S. bayarsaikhanae, slender valva is shorter than apex of uncus, with a short (almost same size to S. trigonica sp. n.) subapical spine on outer margin of cucullus, it is arising immediately near the tip of saccular spine, and aedeagus vesica has a bundle of thin, same sized spines and a weakly waved, larger one (Bucsek 2020: 44, figs 89–92, Bayarsaikhan et al. 2021: 142, figs 14a-b). The female genitalia structure of the present new species is similar to S. munda (De Joannis, 1928) (Bayarsaikhan & Bae 2021: 91, fig. 4B), and S. imorod Chen, Hsu, Chen & Buchsbaum, 2018 (Chen et al. 2018: 41, fig. 4). But the new species can be distinguished from two other species by the globular corpus bursae membranous and bent appendix bursae strongly sclerotized whole of length. In S. munda, corpus bursae is irregularly ovoid and strongly sclerotized, except membranous medial area, and membranous appendix bursae with strongly sclerotized plate in cervix area. In S. imorod, globular, membranous corpus bursae has strongly sclerotized plate, its covered spines and appendix bursae is weakly sclerotized along whole length. Description. Adult (Figs 11a, b). Male and female are superficially similar. Length of forewing 6 mm in male (Fig 11a) and female (Fig 11b). Head and frons pale gray; labial palpus dark, slender, upturned. Patagium, tegula and thorax pale gray. Ground color of forewing pale gray; basal and costal area tinged with fuscous; antemedian series of three large, dark spots distinct and last smaller one indistinct near tornus; dark brown medial band distinctly convex, interrupted or clouded in cell; a pair distinct discoidal dark spots of discal area different sized, which lower one two times bigger than upper; postdiscal series of dark spots curved outward; before apex with one fuscous patch; terminal series of small spots dark. Hindwing fuscous gray; costal and terminal area narrowly fuscous. Male genitalia (Fig 19). Uncus slender, hook˗shaped, with a small spine at tip, same length with tegumen. Tegumen weakly sclerotized. Valva symmetrical, weakly sclerotized whole of length, basal half of valva broader than rounded apical half, its heavily covered with setose; costa with an angled swollen projection medially; slender, curved cucullus with a subapical spine, which almost six times shorter than saccular spine. Sacculus stout, and blunt apical saccular process with a slender, sickle˗shaped spine, that not extend into small spine on outer margin of cucullus. Juxta arched and apical lobe of juxta heart˗shaped. Aedeagus stout and vesica with a large, wrinkled, tapering spine and an area of thin, diverse sized spines, and finely scobinate. Female genitalia (Fig 24). Papillae anales triangular, weakly sclerotized. Apophyses posteriores about three times as long as apophyses anteriores, both apophyses slender. Ostium broadly waved, weakly sclerotized. Ductus bursae broad funnel-shaped, weakly sclerotized, two times shorter than corpus bursae. Corpus bursae globular, membranous, with a broad area of strongly sclerotized spines in cervix. Bent appendix bursae strongly sclerotized whole of length. Distribution. SW Thailand (Chumphon and Ranon provinces). Etymology. The specific name is derived from the Latin “ trigonicus ” meaning “triangles”, refers to the shape of dark brown medial band of forewing., Published as part of Bayarsaikhan, Ulziijargal, Cha, Yeong-Bin, Černý, Karel, Kwon, Hyung-Wook & Bae, Yang-Seop, 2022, Review of the genus Stictane Hampson (Lepidoptera, Erebidae, Arctiinae) in Thailand with description of a new species, pp. 481-491 in Zootaxa 5138 (4) on pages 489-490, DOI: 10.11646/zootaxa.5138.4.8, http://zenodo.org/record/6571781, {"references":["Snellen, P.

Halone arcuata Bayarsaikhan & Bae, sp. nov. (Figs. 1, 5, 9) Type materials. Holotype: ♂, Vietnam, Prov. Ninhbinh, NP. Cucphuong, 1.V.2005 (YS Bae & JM Kim), Gen. Slide No. INU˗10303 V, deposited in PPRI. Paratypes (1 ♂, 2 ♀) VIETNAM: 1 ♂, 2 ♀, same data as for the holotype, Gen. Slide No. INU˗10156 V (female), 10429 V (female), 10431 V (male), deposited in INU. 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. MalS25; 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. MalS26; 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. Description Adult (Figs. 1a, 1b). Length of forewing 6˗7 mm in males (n=2), 7˗7.5 mm in females (n=2). Head, patagium, tegula and thorax sordid white, mixed with brown scales. Forewing ground color sordid white, with pale brown sprinkles; medial discal area with a short, longitudinal dark brown streak (antemedial and discocellular patches almost connected); cilia sordid white. Hindwing pale brown; cilia gray. Abdomen fuscous in both sexes, tinged with pale yellow in females. Male genitalia (Figs. 5a, 5b). Uncus stout, acuminate, with a stout and apically rounded ventral process. Tegumen weakly sclerotized, strongly shouldered, with roundly arch-shaped apical projection. Anal tube membranous, scaphium weakly trapezoid, with weakly sclerotized edge. Distal section of valva membranous, sparsely setose, narrow, apically rounded, almost equal in length to tegumen. Saccular process strongly arcuate, sclerotized, with dentate proximal half and with acuminate apex, almost equal in length to valva. Saccus broadly “U”˗shaped. Aedeagus stout, weakly sclerotized; vesical scobinated, with seven slender spines and elongate, sclerotized tube. Female genitalia (Fig. 9). Papillae anales weakly covered with setose. Postvaginal plate sclerotized, “bow tie”˗shaped, densely serrulate.Antrum sclerotized, broadly rounded, with slightly waved posterior margin with a shallow incision medially. Apophysis posterioris slender, about 2 times longer than thiker apophysis anterioris. Lamella antevaginalis strongly sclerotized, horizontally elongated, arch-shaped. Right section of ductus bursae heavily sclerotized and tubular, while left section broad, membranous, with rectangular sclerotized plate. Corpus bursae globular, membranous, with a strongly dentate signum medially. Distribution. Vietnam (Ninhbinh Prov.). Etymology. The specific epithet is derived from the Latin “ arcuatus ” meaning “arched”, refers to the arched saccular process and arch˗shaped projection of tegumen in the male genitalia.

This species was described from Thailand as a member of the genus Eugoa by Čern�� (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 (Čern��, 2009), comb. nov. Original description of adult by Čern�� (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.

IX. 2018 (Bae Y.S., Na S.M., Lee D.J., Ko J.H., Lee T.G., Cha Y.B., Jang C.M.), genitalia slide No. INU-9467 (INU). Diagnosis. Meganola canaliculata sp. n. is confusingly similar to all other species of the M. strigivena speciesgroup, the reliable identification requires the examination of the copulatory organ. Based on the configuration of the male genitalia, the new species is a sister species of M. zirkalmashka László, Ronkay & Ronkay, 2014 known from East Nepal and India-Sikkim. The two species have a nearly identical configuration of the clasping apparatus, but M. canaliculata sp. n. has a somewhat shorter basal lobe of valva and noticeably longer and thinner, evenly curved, and more pointed harpe, which is upcurved basally and straight or even slightly S-curved distally in M. zirkalmashka. The configuration of the aedeagus of the two species is nearly identical, the only noticeable difference is the slightly longer cornutus of the vesica in the new species compared to its congener. The female is unknown. Description. Adult (Figures 3, 4). Length of forewing 7–9 mm in males. Male antenna bipectinate. Frons and vertex irrorated with fuscous green scales. Patagium and tegula (Figures 3b, 4b) with a fuscous green circular patch. Labial palpi porrect. Ground color of forewing bright gray; antemedial line curved; medial line semi-circular in costal, strongly zig-zagged in the dorsal area; postmedial line broadly curved in costal half, following the arch of medial line, pointed inwards medially, arched in dorsal third; subterminal line wavy, interrupted; terminal line fine, continuous; cilia gray, chequered with black. Ground color of hindwing pale brownish-gray, with dark discal spot and fine terminal line. Male genitalia (Figures 8a, 9a). Uncus medium long, tapering, apically pointed; subscaphial process short and narrow, with small, densely setose rounded tip. Tegumen simple, narrow. Costal margin of valva sclerotized, slightly concave, somewhat bulged subbasal; apical section of valva moderately dilated, apex rounded; basal lobe present, short and broad; harpe conspicuously long, thin, evenly curved, pointing posteriorly, very finely dentate subapically, pointed apically. Juxta narrow, somewhat V-shaped, antero-laterally pointed, strongly sclerotized. Sacculus slender, width approximately same as subbasal area of valva costal margin. Saccus long, elongate Vshaped.Aedeagus tubular, relatively long, slender, carina process pointed, spine-like; vesica with one robust, basally broad, apically pointed, slightly curved spine-like cornutus. Eighth tergite (Figures 8b, 9b) with triangular medial plate with concave margins, anteriorly with two short, curved, apically pointed processes; 8 th sternite (Figures 8b, 9b) with two weakly sclerotized triangular posterior plates. Female unknown. Distribution. Laos (Xiengkhouang Province). Remark. The fuscous green circular mark on the patagium and tegula tells apart Meganola canaliculata sp. n. from the sympatrically occurring Meganola phuana sp. n. However, this character is only recognizable in freshly hatched, intact specimens. In all other cases, reliable identification requires the dissection of the genitalia. This species was collected from the lowland to the mid montane zone (Figure 11). Etymology. The new species is named based on the botanic Latin word, canaliculatus. It means long and concave, to resemble a gutter or channel. This species is characteristic of long and concave harpe., Published as part of Cha, Yeong-Bin, László, Gyula M., Bayarsaikhan, Ulziijargal, Ko, Jae-Ho, Lee, Tak-Gi, Jang, Chang-Moon, Kim, Hanul, Kim, Jeong-Nam & Bae, Yang-Seop, 2021, Two new species and a new record of the genus Meganola Dyar, 1898 (Lepidoptera, Nolidae, Nolinae) from Laos, pp. 423-430 in Zootaxa 5032 (3) on pages 425-426, DOI: 10.11646/zootaxa.5032.3.7, http://zenodo.org/record/5497025, {"references":["Laszlo, G.

Meganola phuana Cha & Bae, sp. n. (Figures 1, 2, 6, 7) Type material. Holotype: ♂, Laos, Xiengkhouang Province, Ban Tha (N19°43'28.92'', E103°35'26.02'', Alt.: 1,245m), 01. IX. 2018 (Bae Y.S., Na S.M., Lee D.J., Ko J.H., Lee T.G., Cha Y.B., Jang C.M.), genitalia slide No. INU-9479 (INU). Paratype. 1♂, with the same data as in the holotype, genitalia slide No. INU-9478 (INU). Diagnosis. Though belongs to the M. flexuosa species group, Meganola phuana sp. n. is very similar externally to the members of the M. strigivena species group but can be distinguished by the more broadly arched costal and straight dorsal section of the postmedial line. Based on the configuration of the male genitalia, namely the robust, finger-like, distally serrate harpe and the narrow, triangular basal lobe of the valva, the new species’ closest kin is M. nanlinga Hu, László, Ronkay & Wang, 2013 described from the Nanling Mountains in Guangdong Province, China. However, the two species are easily distinguishable by the following characters: Meganola phuana sp. n. has somewhat narrower, apically slightly more pointed and noticeably darker forewing and considerably less excessively zigzagged dorsal section of the medial line compared to those of M. nanlinga. In the male genitalia, the new species compared to M. nanlinga has slightly shorter and narrower uncus, somewhat thicker subscaphium arms, markedly narrower valva without dilated apical part, slightly shorter harpe, narrower basal lobe of valva, and broader saccus; in addition, the ventral margin of the sacculus is obtuse-angled in Meganola phuana sp. n., while it is rounded right-angled in its congener. The aedeagus of the new species is noticeably slimmer than that of the allied species, with its vesica bearing somewhat smaller spine-like cornutus, situated more distally than in M. nanlinga. The female is unknown. Description. Adult (Figures 1, 2). Length of forewing 8–9 mm in males. Antenna bipectinate in male. Frons and vertex pale gray, mixed with brownish-gray scales. Patagium (Figures 1b, 2b) with a black line basally. Ground color of forewing pale brownish gray; basal area dark grayish brown, the upper side of cell brownish-green until medial line; antemedial line angled medially; costal half of medial line diffuse, dorsal half sharply defined, zigzagged; postmedial line curved in costal half, almost straight in dorsal half; postmedial area with indistinct grayishbrown fascia gradually widening in the medial part of terminal area until the outer forewing margin; subterminal line interrupted; terminal line continuous, pale ivory. Ground color of hindwing pale grayish brown, with a dark discal spot. Male genitalia (Figures 6a, 7a). Uncus short, tapered, apically rounded, subscaphium process relatively thick, apically rounded, densely setose. Tegumen relatively short and narrow. Valva narrow, apically rounded, costal margin sclerotized, dilated basally, slightly concave; ventral half of valva membranous, ventral margin almost straight, very slightly concave in basal third; basal lobe short, narrow, triangular; harpe stout, finger-like, posterior margin serrate, basally bifurcate, postero-medial branch expanding to costal margin of valva, lateral one connected to sacculus. Juxta V-shaped, antero-laterally pointed. Sacculus sclerotized, ventral margin obtuse-angled. Saccus robust, elongate V-shaped. Aedeagus constricted medially, main tube thinner than coecum penis, vesica armed with a small, acute, spine-like cornutus. Eighth tergite (Figures 6b, 7b) with quadrangular medial plate with gently arched margins, anteriorly with two very short, straight, apically rounded processes, erecting near the corners of the medial plate; 8 th sternite (Figures 6b, 7b) with a wide trapezoidal medial plate. Female unknown. Distribution. Laos (Xiengkhouang Province). Remark. This species was collected in the upper montane zone, up to 1,200m a.s.l. (Figure 11). Etymology. The new species is named after the Phuan people inhabiting the Xiengkhouang Plateau, where the new species was collected.

Diagnosis. By the wing pattern of this species, it is hardly distinguishable from many others of the genus Diduga. However, in male genitalia, broadly rounded, membranous apex of weakly tapering valvae with a short apical spine in right valva, but that apical spine absent in left valva; aedeagus vesica with a large stout, and 3–4 (four in holotype) stout, almost same sized, short (nearly 1/3 length of large one), and one slender (almost half size of large one), spine˗shaped cornuti separates this species well from all the other known Diduga. Description. Adult (Figs 2a, 2b). Length of forewing 6–7.5 mm in male. Head, patagium and tegula deep yellow. Dark brown thorax edged by deep yellow, slender band apically and laterally. Forewing ground color dark brown, with broad, deep yellow costal margin, which hind border broadly waved, and with row of small, dark brown dots in costal and terminal area; apex of forewing strongly angled; cilia deep yellow. Hindwing ground color pale brown; cilia pale brown. Abdomen brown, with deep yellow anal tuft in male. Male genitalia (Figs 10a, 10b). Uncus stout, tapering, apical area weakly bent, basal area broadened, with a bundle of spines ventrally, almost same length with tegumen. Tegumen triangular, weakly sclerotized. Valvae weakly sclerotized, slightly tapering, broadly rounded apical area edged by membranous narrowly, with apical short spine in right valva, it is absent in left; costal margin more sclerotized than harpe area of valva, with a broadly rounded spur in subapical area and a large rounded spur in basal area of costal margin; in right valva, apical area rounded, narrowly edged by membranous, apical short spine absent. Juxta broadly truncate. Saccus roundly U˗shaped. Aedeagus stout, short (2/3 length of valva), and vesica with totally six diverse sized spine˗shaped cornuti, which a large (almost half length of aedeagus) stout one, and 3–4 (four in holotype) stout, almost same sized (nearly 1/3 length of large one), and slender (almost half size of large one) one, and finely covered with scobination. Female genitalia. Unknown in Laos. Distribution. Laos (Xiengkhouang Province). Etymology. The species name is derived from the Latin mucronatus (= pointed), referring to the rounded apex of right valva with a hard short spine in male genitalia.

The new species has no remarkable external differences from a number of other members of the genus. The genitalia structure of the new species is similar with Diduga bayartogtokhi (Bayarsaikhan & Bae, 2019: 368, figs. 11, 17), but can be distinguished from the latter by the rod˗shaped largest one of three irregular apical projection of left valva acuminate, dentate margin; right valva with three stout, acuminate, stout rod–shaped projections; arched juxta with truncated apex and strongly sclerotized, curved apical spine in male genitalia; in female genitalia, ostial plate rounded, not divided to parts; distal half of corpus bursae covered with dense spinulose scobination. In D. bayartogtokhi, largest apical projection of left valva truncated, with asymmetrically bifurcated apex; one large, triangular process of right valva with dentated edge; reverse V–shaped juxta with rounded apex and without apical spine in male genitalia; in female genitalia, ostial plate consisting three spurs, with strongly dentated edge; corpus bursae covered with dense spinulose scobination wholly. Description. Adult (Figs 1a, 1b). Length of forewing 5.5–6 mm in both sexes. Head and patagium deep yellow. Proximal end of tegula deep yellow, distal end dark brown. Thorax dark brown, with slender deep yellow apical band. Forewing ground color dark brown, with broad, deep yellow costal margin, which hind border broadly waved; with two dark distinct dots in antemedial and postmedial line, and small, dark brown dots in costal and terminal border; cilia deep yellow. Hindwing ground color dark brown; cilia dark brown. Abdomen brown, with deep yellow anal tuft in male. Male genitalia (Figs 11). Uncus stout, apex angular, heavily covered with setae. Tegumen triangular, weakly sclerotized. Valvae asymmetric: in left valva, narrower than right, apex rounded, membranous, with rod˗shaped spur in harpe and two costal margin’s processes, which stout upper one with diverse sized small apical spines and slender, spine˗shaped lower one broadened to basally (process of harpe almost two times longer than same sized processes of costal margin); basal area of costal margin with strongly sclerotized, weakly dentate, small arch˗shaped spur; in right valva, apex of valva with three large, stout apical processes; cucullus large, membranous, rounded apex. Juxta arched, tip strongly rectangular, with a strongly sclerotized, curved apical spine. Saccus broadly “U”˗shaped. Aedeagus stout, short, with sclerotized spine in distal half and vesica membranous, without cornutus. Female genitalia (Fig 19). Papillae anales weakly covered with setae. Lamella postvaginalis weakly sclerotized, broadly arch˗shaped; lamella antevaginalis strongly sclerotized, consisting two lateral spurs, heavily covered with short spines. Ostium bursae membranous, wrinkled. Ductus bursae membranous, with partly wrinkled, sclerotized band. Corpus bursae ovoid, weakly wrinkled, with dense spinulose scobination in basal half. Distribution. Laos (Bolikhamsai Province). Etymology. The species name is derived from the Latin hastatus (= halbert–headed, like the head of a halbert), referring to three large projections of right valva in male genitalia.
