The Dorippus tiger (''Danaus dorippus'') is a butterfly belonging to the danaine group of the Brush-footed butterflies family. ==Systematics and taxonomy== ''Danaus dorippus'' was formerly regarded as a subspecies of ''Danaus chrysippus'', the ''plain tiger'' or ''African monarch''. It is now regarded as a distinct species. It appears (from analysis of mtDNA sequences, which are only inherited from the mother) that the dorippus tiger is the product of an ancient lineage of ''Danaus'' hybridizing with plain tiger females.〔Smith et al. (2005)〕 As the plain tiger is known to be parasitized at least occasionally by ''Spiroplasma'' bacteria which selectively kill off male hosts,〔Jiggins et al. (2000)〕 a subsequent scarcity of plain tiger males might have led to this hybridization and the evolution of the dorippus tiger. From the color pattern of this species, it can be assumed that the ancient lineage had no black apex on the forewings, as this character is still absent in ''D. dorippus''.
