Diagnosis. This species is most similar to Apsidophora chandrapatyae. The crescent mark on forewing of A. bala is wider than in A. chandrapatyae. Costal margin on hindwing slightly curves in A. bala but it is convex in A. chandrapatyae. Sex scales on male abdominal segment and modified scales between M 3 and CuA 2 are absent while they are present in A. chandrapatyae. Cucullus of A. bala is slightly narrow to apex and less curve but it is more parallel and evenly curve in A. chandrapatyae.
Description. Head (Figs. 5–6): Lower frons brownish white, upper frons light brown; vertex light brown mixed with brown; labial palpus porrect, first segment brownish white mixed with light brown, second segment enlarged, margin parallel, yellowish brown, with brown spot dorsobasally, apical 1/4 with transverse brown line, apical segment small, yellowish brown. Antenna light brown.
Thorax: Pronotal collar brown, slightly paler posteriorly; tegulae light brown, darker anteriorly, each scale yellowish brown at tip; mesonotum without posterior crest, light brown, each scale with yellowish brown at tip, anterior 1/5 with transverse brown band. Hind tibia with tuft of long, whitish hair pencils extend from base to near apex, above with tuft of shorter, greyish brown hair pencils extending from base to apical 3/5 (Fig. 17). Forewing rectangular, length 7.1–7.7 mm in males (n = 7) (Figs. 2, 14), 6.8–8.4 mm in females (n = 3) (Fig. 3), basal half of costa slightly curve, apical half more curve, costa with well developed strigulae, especially apical 2/3, yellowish white separated by dark brown, termen rather round, rounded apex, ground color yellowish brown mixed with diffuse, small, brown and dark brown spots, wing base with small subtriangular patch, dark brown, basal 1/3 with irregular dark brown patch extending from costa to between Sc and R 1, dorsum patch large, dark brown, extending from middle of dorsum and strongly curved outwardly to termen, upper edged by yellowish white narrow line, upper margin extending gently curved from basal 1/3 of dorsum to termen between M 1 and M 2, lower margin extending from apical 1/3 of dorsum to M 3, then extending downward to termen at CuA 2, tornus with a large oval dark grey patch, slightly paler to termen, with small irregular transverse strip medially, extending from M 3 to tornus, light brown mixed with brown, nearly half of costa with slightly sinuate strip, gradually widened, extending obliquely to near termen between R 5 and M 1, above with light brown narrow strip extending parallel to near termen between R 4 and R 5, in near termen with a transverse dark brown strip extending from wing apex to between M 1 and M 2, beyond with a narrow, transverse white strip on termen extending from below apex to between M 1 and M 2, fringe scales light brown from wing apex to between M 1 and M 2, then dark brown mixed with brown extending to tornus; underside brown except 1/3 above dorsum greyish white, termen with yellowish white between wing apex and M 1 and M 2. Hindwing (Figs. 8, 14) subtriangular, brown, costal margin slightly curve, with modified thickened and rolled anal margin in male, forming long and slender rigid projecting lobe, with group of dense, yellowish white hair pencils originating from between near wing base and basal 1/3, then inserted to the groove beyond middle of lobe (Fig. 9) long as length of projecting lobe (Fig. 14), fringe scales brown except from CuP to projecting lobe in male, brown in females, slightly paler on anal margin; underside of hindwing light brown, slightly darker to costa.
Abdomen: Male genitalia (Fig. 19) with tegumen high, moderately widened, with dense scale sockets laterally; uncus long about 1/3 of tegumen length, truncated apex, posterior surface with dense setae, more dense near apex, posterobasal half without setae; socii moderately large, subtriangular lobe, densely setose; gnathos arising from basal 1/3 of tegumen length, forming moderately large membranous band, sclerotized at base; vinculum moderately sclerotized; juxta subpentagonal; caulis shot; anellus surrounding at basal 1/4 of phallus; phallus rather shot, slightly curve, wide at base and tapered to apex; cornuti absent; valva long and slender, sinuate, margins slightly narrow to rounded apex; sacculus with a small group of moderately dense setae basally, ventromedially with a moderately large group of dense setae, slightly narrow to ventrobasally of cucullus, with a small group of shot setae on basal opening margin medially; cucullus longer than sacculus, densely setose, ventral half with strongly spines except apical 1/4 of cucullus, with group of dense, moderately long spines dorsobasally.
Female genitalia (Figs. 22–23) with papillae anales densely setose; tergum VIII smooth, with dense scale sock-ets on subtriangular extension; sternum VII weakly sclerotized, with dense scale sockets, more dense along excavat-ed posterior margin; sterigma forming moderately large, reticulated subquadrate plate, with vertical split-like ostium between two subtriangular, aciculate lobes, pointing outwardly (Fig. 23); colliculum moderately sclerotized, long about 1/4 of ductus bursae length; ductus bursae rather narrow, margins parallel to ostium bursae; ductus seminalis arising from posterior 1/3 of ductus bursae; corpus bursae ovate, granulate throughout, signa unequal, large signum funnel-shaped, rounded apex, apex rather narrow, with widened hollow base, small signum subtriangular, rounded apex, subelliptical hollow base.
Etymology. The specific epithet bala refers to Bala Wildlife Research Station (Hala-Bala Wildlife Sanctuary), the location of holotype.
scales in square mark 16. Sex scales on hindwing. (A = row of leaf-liked scales on M 3, B = large patch of appressed rounded scales between CuA 1 and CuA 2), scale bar = 2 mm.
