ABSTRACT A new combination and a new status, Pachira manausensis, is here proposed. After making field observations and analyzing type and herbarium specimens, we realized that P. aquatica var. manausensis should be treated as a species due to many morphological and distribution differences compared to the typical variety. We provide detailed descriptions and a distribution map, table, key, and plate to distinguish both species using morphological characteristics. Typifications and nomenclatural notes for related names were performed.

Resumo Quararibea bovinii é proposta como uma nova espécie para a Mata Atlântica. Sua distribuição é restrita ao sudeste do Brasil, ocorrendo nos estados do Espírito Santo, Rio de Janeiro e São Paulo. É semelhante a Q. similis em relação à morfologia das flores e forma dos frutos, mas se distingue pelo indumento das folhas, a largura das folhas e a forma das sementes.

Abstract In the present study, I propose a new species, Quararibea bovinii, an Atlantic Forest tree. The new taxon occurs in southeastern Brazil, in the states of Espírito Santo, Rio de Janeiro, and São Paulo. It resembles Q. similis in terms of floral morphology and fruit shape, but it is distinguished by the indumenta of leaves, leaf width, and seed shape.
