Hyphessobrycon zoe 
Faria, Lima & Wosiacki, 2020

A new species of Hyphessobrycon from a tributary of the Rio Paru do Oeste (Rio Trombetas basin), at the lower Amazon basin draining the Guiana Shield region in Pará State, Brazil, is described. The new species presents a unique combination of an irregularly-shaped humeral blotch, a broad diffuse midlateral stripe, and a roughly triangular caudal peduncle blotch. The new species is herein included in the Hyphessobrycon agulha species-group, and comparisons with species belonging to this group and to a similar-looking non-congener, Hemigrammus bellottii, are presented.

Etymology.— The specific epithet honors the Zo'é, a Tupi-speaking people living at the Rio Cuminapanema, a tributary of Rio Curuá, very close to the area from where Hyphessobrycon zoe is known. The Zo'é were only discovered by the western society during the 1970s and contacted during the 1980s, being one of the indigenous people from South America that has retained more of its traditional culture (Hemming, 2003). A noun in apposition.
