Limbobotys acutangulalis Ko & Bayarsaikhan & Kim & Bae 2025, comb. nov.

Limbobotys acutangulalis (Swinhoe, 1894) comb. nov. (Figs. 5, 10, 15) Circobotys acutangulalis Swinhoe, 1894: 143–144. TL: Cherrapunji, Meghalaya, India. Diagnosis. This species is similar to L. digitatus sp. nov. in wing patterns, but it can be distinguished by the following characteristics: the apex of the narrow forewing is pointed (wide forewing with apex rounded in L. digitatus sp. nov.); the termen is strongly oblique and straight (relatively rounded in L. digitatus sp. nov.); the abdomen is narrower and longer than that of L. digitatus sp. nov. In the male genitalia, the sella is bilobed, with the dorsal and ventral lobes being arciform (irregularly oviform and digitate in L. digitatus sp. nov.); the phallus is shorter than that of L. digitatus sp. nov., with a long, spiny, stem-shaped bundle of cornuti (lacking cornutus in L. digitatus sp. nov.). Material examined. (4 ♂): LAOS: 2 ♂, 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-7046, 7047; 1 ♂, PKK National Park (N18˚27′9.78″, E103˚03′42.62″ Alt. 445 m), 6.VIII.2016 (Bae Y.S., Park B.S., Na S.M., Lee D.J., Ko J.H.), missing abdomen; 1 ♂, PKK National Park (N18˚27′23.76″, E103˚03′05.15″ Alt. 470 m), 27.VII.2018 (Bae Y.S., Lee D.J., Ko J.H., Lee T.G., Jang C.M., U. Bayarsaikhan), genitalia slide no. INU-7178. Distribution. Laos (new record), India. Remarks. This species is newly recorded from Laos in this study. It lacks the characteristic scale tufts on the ventral side of the male forewing, and its forewing shape differs slightly from those of other species in the genus. Nevertheless, it shares several key characteristics with Limbobotys, including similar wing patterns, the presence of two foveae on the dorsal surface of the forewing, and a bilobed sella and phallus shape in the male genitalia. Based on these external features, we propose its new combination within the genus Limbobotys. However, it also exhibits distinct traits (such as the shapes of the abdomen, forewing, and phallus) that set it apart from other congeners. These differences suggest that it may belong to a separate, possibly new genus, potentially allied with other similar species, and that further taxonomic research is needed.
