Female. Unknown.

Etymology. The specific name refers to B (B.) diospyri Drew, 1989 , to which the new species is similar.

Material examined. Holotype 3( IZCAS), China: Yunnan: Nujiang Lushui, Pianma 1695m, 98º58’00’’, 26 º11’00’’, 30 July 2009, Wang Shaojun and Zhao Kanglin, attracted to Cue lure; Paratype 3 ( IZCAS), the same data with Holotype.

Distribution. China, Yunnan (Nujiang)

Attractant. Cue lure.

Host. Unknown.

Remarks. This species is similar to B (B.) diospyri Drew from Australia and B (B.) passiflorae (Froggatt) from Fiji, Tonga and Niue in scutum and abdomen completely black, but differs from B (B.) diospyri in face lacking a large black subquadrate facial spot and the wing with costal band widening slightly beyond tip of R2+3. And differs from B (B.) passiflorae in the wing with costal band widening slightly beyond tip of R2+3 and the fore and mid femora black, apical 3/4 of hind femora shining black, fore and hind tibiae dark fuscous, mid tibiae black and tarsi fuscous. This species also similar to B (B.) nigrofemoralis White & Tsuruta from Karnataka in scutum, fore and mid femora black, and similar wing pattern, but differs from B(B.) nigrofemoralis in scutum completely black and lacking two yellow narrow lateral postsutural vittae, abdomen completely black and lacking red brown bands and areas, also in 3/4 hind femora black and remainder fulvous.
