Eumorpha danielis (Schrottky, 1907) and Centris nigrita var. raymondi Schrottky, 1907, are trasferred to Euplusia Moure, 1943 and validated as Euplusia danielis and Euplusia raymondi comb.n.. Specimens from Santa Isabel do Morro, Ilha do Bananal, Tocantins, and from Santarém and Cachimbo, Pará, are described as Euplusia danielis fuscatra subsp.n., Euplusia fragocara Kimsey, 1977, was discovered in Ouro Preto d'Oeste, Rondônia; its female shows bluish colors as E. caerulaescens (Lepeletier, 1841), and E. violacea (Blanchard, 1840). The true meaning of E. smaragdina (Perty, 1833) as different from E. surinamensis (Linnaeus, 1758) is restored according to the study of the type specimen in Munich, Germany. E. xantha Kimsey, 1977 is a new synonym of E. vidua Moure, 1976. The following species from Brasil are described as new: Euplusia faceta from Mucujé, Bahia, Euplusia nordestina from Santa Luzia, Paraiba, and Euplusia velutina from Mérida, Northwestern Venezuela.
