Abstract:
Microcambeva watu, new species, is described from the Rio Doce basin in the Atlantic Forest of southeastern Brazil. It is distinguished from all congeners by the presence of a heart-shaped blotch on top of head. It differs from M. ribeirae, M. filamentosa, and M. bendego by presenting an ossification in the anterior cartilage of autopalatine. It is distinguished from M. barbata by the anterior rudimentary ossification of autopalatine and from M. mucuriensis and M. draco by a bifid ventral tip of opercle. Finally, it also differs from M. jucuensis by having an ellipsoid metapterygoid lacking a ventral process. This is the eighth described species of Microcambeva, most of them in the last ten years. Comments on the systematics, biogeography, and conservation of the new species are provided.
