n. sp. and coinfection in (Aves: Cariamiformes): first mitochondrial genome analysis and morphological description of a leucocytozoid in Brazil.

The distribution of avian haemosporidians of the genus in the Neotropics remains poorly understood. Recent studies confirmed their presence in the region using molecular techniques alone, but evidence for gametocytes and data on putative competent hosts for are still lacking outside highland areas. We combined morphological and molecular data to characterize a new species infecting a non-migratory red-legged seriema (), the first report of a competent host for in Brazil.
