Abstract

Based on new samples from the Atlantic Forest between northern São Paulo and southern Bahia, Brazil, we clarify taxonomic relationships in two little-known species of Mouriri. As a result, we synonymize M. megasperma and M. sellowiana under M. arborea, and M. bahiensis under M. regeliana. We designate a lectotype for M. sellowiana, as the holotype was destroyed during World War II. In addition, we present updated morphological descriptions, data on geographic distribution, conservation status assignments, illustrations, and comments on taxonomic and nomenclatural aspects of M. arborea and M. regeliana. Photographs based on fresh material of M. arborea are presented.
