Pectoral Fin Rays

Rineloricaria daraha, new species, is described from the rio Daraá, tributary of rio Negro, northwestern Amazonas State, Brazil. The new species is diagnosed by having seven branched pectoral-fin rays, finger-like papillae on the lower lip, a large multi-angular preanal plate, and at least four quadrangular plates of variable size surrounding the preanal plate. The new species is known only from rio Daraá and its waterfalls.

Rio Negro Basin

Macrolobium is a neotropical genus with approximately 80 species distributed from Central to South America. In Brazil, the upper Rio Negro basin in Amazonia is the center of diversity for the genus. A taxonomic study based on the type materials and additional specimens of M. campestre deposited in several herbaria was carried out. The results show that the taxonomic diversity at the infraspecific level has been overestimated. Thus this work proposes synonymizing Macrolobium campestre var. arirambense R.S. Cowan, M. campestre var. arboreum R.S. Cowan, M. campestre var. longibracteatum R.S. Cowan and M. campestre var. medium R.S. Cowan under Macrolobium campestre Huber.
