Brazil and Guiana = north-eastern Brazil.
Mentioned by Marcgraf in 1648, its true existence was questioned for a long time until its rediscovery in 1951. All members of genus have been placed, together with the members of Pauxi, and less often Nothocrax, in Crax. In the past present species often considered conspecific with M. tuberosum, and three of 20 captives sampled genetically showed evidence of being hybrids with that species#R, but other molecular data suggest that present species is most closely related to M. tomentosum#R and have also confirmed its validity#R. Moreover, plumage characters suggest its distinctness at species level. Monotypic.
NE Brazilian coast, in recent decades only in Alagoas; formerly also in E Pernambuco; report of occurrence in N Bahia seems to be unreliable. Probably now extinct, or virtually so, in the wild#R.
