This species is easily recognizable by the orange elytra without maculation. The only species similar to B. bipartita is B. westwoodii, but B. westwoodii is much larger and has the pronotum almost entirely orange with only a basal black macula (Nestor-Arriola and Toledo-Hernández 2016). The material was identified following the description of Mulsant (1850) and considering the information of Booth and Pope (1989).
