Blue Vanga is split into two species, based on differences in plumage in both sexes (del Hoyo and Collar 2016). The polytypic group Blue Vanga (Comoro) Cyanolanius madagascarinus comorensis/bensoni becomes Comoros Blue Vanga Cyanolanius comorensis, with subspecies comorensis and bensoni; and the monotypic group Blue Vanga (Madagascar) Cyanolanius madagascarinus madagascarinus becomes Madagascar Blue Vanga Cyanolanius madagascarinus.
