Diagnosis. This new species is similar to B. abdita in male genitalia. In B. tinsukiaensis the uncus abruptly bent medially, socii not prominent, tegumen broader at base and apex narrower, juxta large and apically broader. In contrast, in B. abdita uncus is bent basally, socii is prominent with bristles, tegumen is broad and juxta is relatively smaller.
Description. Head: Clothed with mustard yellow scales in male and light yellow scales in female. Ocellus well developed. Vertex and apical part of frons clothed with anterior and forward projected cream yellowish scales, base of frons with small appressed upwardly projected light amber colored scales. Labial palpi three segmented, first segment short and broad with brownish orange scales, second segment long and curved, cream interspersed with dark brown scales along dorsal margin from base to near apex, small third segment pale brown. Antenna filiform, covered with brownish orange scales with intersegmental short cilia. Chaetosema present.
Thorax: Pronotal collar, tegulae, mesonotum, and posterior crest cream, mixed with dark brown, interspersed with dark gray and flax yellow scales; mid-legs with pair of tibial spurs; hindtibia covered with dense, brownish orange scales in male, inner margin with a tuft of long, brownish orange long hair pencil, originating from base (Fig. 9). Forewing subrectangular, broad; wing span 18 mm in male, 16 mm in female; costal margin curved, convex medially; ground color brownish orange, interspersed with dark grey scales; basal half of wing with several irregular dark grey patches; along costal margin 6–7 dark grey, narrow, sinuate, transverse striae with subrectangular large median patch; dorsum with large, semicircular tornal patch, brown, mixed with dark brown, apically with irregular striae, apex with small dark brown spot; costal strigulae well developed, cream, each separated by a dark brown streak; termen slightly curved from apex to CuA 1, then strongly curved to tornus; underside of forewing brown, with pale brown marks along costa. Hindwing subtriangular, dark brown, anal margin in male with modified, long, sclerotized, shallow groove without scales (Fig. 7), absent in female; female forewing subrectangular, smaller than in male, pale creamy yellow background and dark grey scales; cilia concolorous with ground color. Male with single stout frenular bristle and female with 3 thin frenular bristles.
Abdomen: Abdomen covered with dark brownish orange scales dorsally, creamy yellow ventrally, abdominal tuft in male also cream-yellow. Female with broad abdomen, dark greyish brown scales dorsally, yellowish brown ventrally. Male genitalia (Figs. 11–13): Tegumen subtriangular, dorsolaterally with small angled shoulders; socius small; uncus long, sclerotized, curved medially, apex spatulate; gnathos weakly sclerotized bands, arising near middle of tegumen, slightly widened towards middle, medially concave and connected to membranous anellus, gnathal hook absent; valva membranous, long and slender, symmetrical; vinculum moderately sclerotized; juxta large, subtriangular, apex broader; anellus wide, cup-shaped; transtilla weakly sclerotized, transtilla process well developed; caulis moderately large; sacculus basely broad and narrow apically, with moderately dense sockets basally, continued as row of short setae reaching base of cucullus, medially with patch of dense setae from margin of basal opening to base of cucullus, dorsal margin with a large hump bearing a conspicuous tuft of long bristles; cucullus long, dorsal margin slightly curved, apical margin sinuate, narrow at apex, with rounded elbow at base, covered with mixture of dense, short setae and long spiniform setae except for dorsal and dorsoapical margins, with large, strong spine at ventroapical margin, remainder with bifid and flattened bristles mixed with setae. Aedeagus short, broader at base and narrow towards the apex. Female genitalia (Figs. 18–19): Sternum 7 sclerotized, posterior margin concave and ovate, surrounding ostium and sterigma; tergum 8 sclerotized with moderately dense scale sockets on lateral triangular extensions; papillae anales narrow with dense setae; apophyses posteriores longer than apophyses anteriores; sterigma inverted heart shaped with lamella antevaginalis reduced, lamella postvaginalis with dense microtrichia, heavily sclerotized in posterior half, with sclerotization extending anteriorly as narrow medial band to ostium bursae; ductus bursae long, weakly sclerotized; antrum ovate, connected to moderately sclerotized colliculum, conical; ductus seminalis arising at posterior 1/3 of ductus bursae, corpus bursae large, ovoid, without signum.
