Diagnosis. Neadeloides acridentata sp. nov. is very similar morphologically to N. cinerealis (Moore) and N. glaucoptera (Hampson) , but can be distinguished by the following characters: sacculus with small triangular process and sharply spine–shaped process; phallus with minute circular cornuti in male genitalia ( Figs. 3 View FIGURE 3 , 5 View FIGURE 5 ). As for N. cinerealis , sacculus gradually narrow, with a hook–shaped saccular process; phallus with short, blunt cornutus in male genitalia ( Singh et al., 2019: 288–289, figs. 1–4, 8). As for N. glaucoptera , sacculus angled at distal 1/3, with a hook–shaped saccular process; phallus with a bundle of long, spine–shaped cornuti in male genitalia ( Singh et al., 2019: 286, 288, figs. 5, 9).

Description. Adult ( Figs. 1–4 View FIGURES 1–2 View FIGURE 3 View FIGURE 4 ). Length of forewing 20–21 mm in male. Vertex covered with blond scales; frons flat, blond and white at central and lateral; antenna filiform, longer than forewing (30–31 mm in male) and blond, mixed with white scales at base; ocellus well–developed; chaetosema absent; labial palpus porrect, blond, mixed with white scales; proboscis well–developed, blond, mixed with white scales. Patagium and tegula gray. Ground color of forewing gray, nearly diamond–shaped, with acuminate apex; termen nearly straight; dorsum slightly rounded; fringe gray. Ground color of hindwing gray, whitish from costal margin to M 1 and from dorsum to CuA 2, fan–shaped, with slightly rounded at apex and termen; dorsum nearly straight; fringe whitish, except gray from M 1 to CuA 2 ( Figs. 1–3 View FIGURES 1–2 View FIGURE 3 ). Venation of forewing with 12 veins: Sc free; R 1 free; R 2, R 3 and R 4 common origin; R 2 shortly stalked; R 3 and R 4 fused half length; R 5 and M 1 free, both from upper angle of discal cell; M 2 and M 3 free, both from lower angle of discal cell; CuA 1 and CuA 2 free; 1A free; 2A nearly indistinct; discal cell about 1/2 length of forewing ( Fig. 4 View FIGURE 4 ). Venation of hindwing with 10 veins: Sc+R 1 and Rs free, stalked for most of length; M 1 free, from upper angle of discal cell; M 2 and M 3 free, from lower angle of discal cell; CuA 1 free, near lower angle of discal cell; CuA 2 free, from 2/3 length of discal cell; 1A, 2A and 3A free; discal cell about 1/5 length of hindwing ( Fig. 4 View FIGURE 4 ). Abdomen slender and with gray scales. Male genitalia ( Fig. 5 View FIGURE 5 ). Uncus oblong, rounded, setose at tip; valva spatulate, setose overall, except at basal area; costal margin sclerotized; basal area of valva membranous; 2/3 of dorsum convex prominent; sacculus strongly sclerotized, with two saccular process, upper process sharply caniniform and lower process triangular; juxta heart–shaped; saccus U–shaped; phallus cylindrical, almost same length of valva, cornuti a long, stout spine and sparse, minute–circles.
