A floristic survey of the Papilionoideae in the Serra do Cabral is presented. The region is part of a mountain range belonging to the Cadeia do Espinhaço, located between latitudes 17º18'-18º06'S and longitudes 44º43'-44º10'W, with altitudes from 515 to 1,400 m, where the predominant formations are Cerrado and Campos Rupestres. The subfamily is represented in the area by 12 tribes, 34 genera and 62 species. Twenty five species occur only in Brazil, six are endemic to Minas Gerais State and 17 are restricted to Cerrado. The restricted distribution of most species found suggests that the taxa grows only on specific phytophysiognomies and are dependent of the preservation of these habitats for survival. A list of genera and species, with their respective identification keys, data on the geographical distribution and the phytogeographic domains where species occur are presented.
