Etymology: Eigenmannia: From Eigenmann, 1910, researcher of faunistic studies (Ref. 45335); matintapereira: Named after Matinta Pereira, the mythical figure that haunts people in search of tobacco and coffee in northern Brazil. According to reports, its appearance is marked by a blackened aspect, an allusion to the colour pattern present in this new species.
Eponymy: Professor Dr Carl Henry Eigenmann (1863–1927) was a German-born American ichthyologist. [...] Matinta Pereira is a figure in Brazilian mythology, a witch who turns into a bird at night. Her blackened appearance is said to resemble the colour pattern of this fish species. (Ref. 128868), visit book page.
