Diagnosis. This new species is similar to B. trachymelas in male genitalia. In B. chettalliensis the uncus long, broad abruptly bent medially, valva relatively smaller and more convex medially than later species, socii not prominent, tegumen subtriangular broader at base and apex narrower, juxta large. In contrast, in B. trachymelas uncus is small, bent basally, valva broader and weakly convex medially, socii is prominent with bristles, tegumen is broad, subrecatnagular, juxta is relatively smaller. B. chettalliensis also close resemblance of B. tinsukiaensis but uncus is short, obliqually bent and broad medially in later species whereas uncus is long, uniform width thought the length in B. chettalliensis . Juxta larger, anellus narrow cup-shaped in B. chettalliensis whereas juxta relatively smaller, anellus wide and cup-shaped in B. tinsukiaensis . Gnathos membranous in B. tinsukiaensis whereas moderately sclerotized in B. chettalliensis .

Description. Head: Ocellus well developed. Vertex clothed with anterior and forward projected grey scales. Frons with small appressed upwardly projected light grey scales. Labial palpi three segmented, first segment short and broad, grey, tinged with brown, second segment long and curved, cream, interspersed with light grey along dorsal margin from base to near apex, small third segment grey. Antenna filiform, covered with grey scales with intersegmental short cilia. Chaetosema present.

Thorax: Pronotal collar, tegulae, mesonotum, and posterior crest creamy, mixed with dark greyish brown scales; mid- legs with a pair of tibial spurs; hindtibia covered with dense, pearl white scales interspersed with light grey scales, inner margin with tuft of long snow-white scales in male hair pencil, originating from base of hindtibia ( Fig. 10 ). Wings: Forewing subrectangular, broad, wing span 18 mm in male. Male forewing weakly sinuate and slightly convex in outer half, with cream-orange scales as background interspersed with dark grey; costal margin with 7–8 dark grey, narrow, striae alternating with patches of mustard-yellow, with median inverted subtriangular grey spot, suffused with pale cream. Hindwing subtriangular, dark brown, anal margin in male with a modified, long, sclerotized, elongated lobe without scales ( Fig. 8 ).

Abdomen: Covered with brownish grey scales dorsally, mustard yellow ventrally and abdominal tuft in male also mustard yellow. Male genitalia ( Fig. 14–17 ): Tegumen subtriangular, dorsolaterally with rounded shoulders, inner margin strongly sclerotized; uncus moderately long, sclerotized, abruptly bent and broad medially and narrow towards apex; socius atrophied; gnathos moderately sclerotized, medially concave and connected to membranous anellus, gnathal hooks absent; vinculum moderately sclerotized; valva symmetrical, long and slender, membranous, costa medially bulged out and covered with cluster of bristles and a prominent strongly sclerotized spine; juxta large, subtriangular, with broader apex; anellus cup-shaped and narrow; transtilla sclerotized, transtilla process well developed; caulis moderately large; sacculus basally and medially broad, 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 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 a large, strong spine at ventroapical margin. Aedeagus short and broad, without any cornuti.

Female unknown.
