Diagnosis. Externally, B. vinhphucensis is similar to the nominate subspecies of B. sieglindae Černý, 2016 described from central Laos ( Černý 2016). However, it can be distinguished from the latter by its slightly larger size (in B. vinhphucensis the forewing length is 13–15 mm, while in B. sieglindae sieglindae that is 12 mm), reddish area on hindwing upperside not reaching the dorsum (in B. sieglindae sieglindae the red area always reaches the dorsum). Compared to B. sieglindae sieglindae , the ♂ genitalia of B. vinhphucensis are characterized by the valva being stouter and broader (longer and narrower in B. sieglindae sieglindae ), shorter sacculus, costa with an additional spiny basal process (such a process is absent in B. sieglindae sieglindae , only a medial costal process is present), and aedeagus vesica bearing smaller cornuti.

Distribution. China * (N Guangxi Zhuang Autonomous Region) and N Vietnam ( Spitsyn et al. 2018).
