Male Sincora Antwren (Formicivora grantsaui), a threatened new species described in 2007 and named after Rolf Grantsau, a pioneering ornithologist in Brazil whose obituary is published herein. This species belongs to the Thamnophilidae family, a group targeted by an extensive series of studies ranging from behavior to systematics carried out for over 40 years by Edwin O. Willis, whose obituary is also published in this volume. We dedicate the new Annotated Checklist of the Birds of Brazil published in this volume to Rolf Grantsau and Edwin O. Willis, therefore honoring their ornithological legacies. Photo: Ciro Albano.
