Limbobotys digitatus Ko & Bayarsaikhan & Kim & Bae 2025, sp. nov.

Limbobotys digitatus Ko & Bae, sp. nov. (Figs. 3, 8, 14, 18) LSID: urn:lsid:zoobank.org:act: 8DDEC3B6-A377-4B5D-9F6A-F74E638ED12B Type material. Holotype. [LAOS] ♂, PKK National Park (N18˚27′10.99″, E103˚03′41.06″ Alt. 451 m), 4.VIII.2016 (Bae Y.S., Park B.S., Na S.M., Lee D.J., Ko J.H.), genitalia slide no. INU-7160 (type deposited in the NIBR). Paratype. [LAOS] 1 ♀, PKK National Park (N18˚25′11.75″, E103˚05′12.59″ Alt. 290 m), 29.VIII.2018 (Bae Y.S., Na S.M., Lee D.J., Ko J.H., Lee T.G., Jang C.M.), genitalia slide no. INU-7163. Diagnosis. The length of the forewing is 9–10 mm in both sexes. This species is similar to L. acanthi Zhang & Li in wing patterns, but it can be distinguished by the following characteristics: the postmedial line of the forewing is not zigzag, and a brown subterminal band is present. In the male genitalia, the valva is wider than that of L. acanthi; the sella is bilobed (irregularly oviform and digitate) and lacks setae; the phallus lacks a cornutus. In the female genitalia, the antrum is strongly sclerotized; the ductus bursae is wider than that of L. acanthi; the corpus bursae is kidney-shaped, with small sclerites near the cervix of the bursae. Description. Adult (Figs. 3, 8). Length of forewing 10–11 mm in both sexes. Vertex covered with reddish-yellow scales; frons covered with reddish-yellow scales and white scaled on both sides; antenna filiform, reddish-yellow, mixed with white scales at base; ocellus well-developed; labial palpus porrect, reddish-yellow on the upper half, and white scales on lower half; proboscis well-developed, covered with white scales at base. Patagium and tegula reddish-yellow. Ground color of forewing reddish-yellow; basal area with a deep yellow basal line and irregular patch near dorsum; discal spot deep yellow; discal cell on upper side with two small glandular foveae in male, and absent in female; discal cell on underside with two scale tufts in male, and absent in female; median fascia deep yellow, lightning-shaped; postmedial band brown; terminal area with black dots at ends of veins; fringe reddish-yellow, except for brown near apex. Ground color of hindwing reddish-yellow, except for light yellow from costal margin to M 1 and from dorsum to CuA 2; median area with a deep yellow, V-shaped pattern; marginal shade and fringe brown, except for reddish-yellow from dorsum to CuA 2. Abdomen reddish-yellow, with a white line posterior part of each segment. Male genitalia (Fig. 14). Uncus finger-shaped, with densely setae at apex; valva nearly rectangular, with densely setae on ventral side; sella bilobed, strongly sclerotized, with dorsal lobe irregularly oviform, pointed at distal end, and ventral lobe digitate at proximal part; juxta and saccus U-shaped; phallus cylindrical, weakly bent, obliquely truncate at both ends, approximately half sclerotized, without cornutus. Female genitalia (Fig. 18). Papillae anales ovate; posterior apophyses almost same length as anterior apophyses; antrum strongly scelrotzied; antrum funnel-shaped, strongly sclerotized; ductus seminalis originated near posterior end of antrum; ductus bursae membranous, about twice the length of corpus bursae; corpus bursae kidney-shaped, with a sclerite near cervix bursae and a rhomboidal signum; appendix bursae present. Distribution. Laos. Etymology. The specific name is derived from the Latin word digitatus, which refers to the digitated lower lobe of the sella.
