Limbobotys Munroe & Mutuura, 1970: 294–295 View in CoL . TS: Asopia limbolalis Moore, 1877 , by original designation.

Diagnosis. Limbobotys Munroe & Mutuura, 1970 ( Figs. 1–18 View FIGURES 1–5 View FIGURES 6–10 View FIGURES 11–13 View FIGURES 14–15 View FIGURES 16–17 View FIGURE 18 in the present study), is very similar to the genus Torulisquama Zhang & Li, 2010 ( Zhang & Li 2010, p. 319–323, Figs. 1–9 View FIGURES 1–5 View FIGURES 6–10 ), but it can be distinguished by the following characters: In males, the forewing has two foveae in the basal and median areas (whereas Torulisquama has a semi-transparent area at the base of the forewing), and the ventral side of the forewing bears two scale tufts (whereas Torulisquama has a large cluster of scales). In the male genitalia, the sella is strongly bilobed and exhibits varied morphological forms (whereas Torulisquama has a nearly rectangular, non-bilobed sella); the editum is simple or absent (whereas Torulisquama has sparse, specialized setae). In the female genitalia, the corpus bursae typically bears sclerites near the cervix of the bursae (whereas Torulisquama usually lacks them).

Distribution. Laos (new record), Myanmar, Vietnam, Indonesia, India, Bhutan, China.

Remarks. The genus is newly recorded from Laos in the present study. The discovery of a new species within this genus reaffirms that the foveae on the dorsal side of the forewing and the scale tufts on the ventral side are distinctive morphological features ( Figs. 1–10 View FIGURES 1–5 View FIGURES 6–10 ). Additionally, the varied, bilobed, or modified forms of the sella and the obliquely truncated distal end of the phallus in the male genitalia ( Figs. 11–15 View FIGURES 11–13 View FIGURES 14–15 ), along with the presence of sclerites near the cervix of the bursae in the female genitalia, are consistent across all species ( Figs. 16–18 View FIGURES 16–17 View FIGURE 18 ). These traits are regarded as the most distinctive and defining characteristics of the genus.
