Distribution map of Hyphessobrycon itaparicensis. White and red stars represent the type localities of H. itaparicensis and H. sergipanus, respectively. Some circles indicate more than one sampling site. Names of the main drainages of the Northeastern Mata Atlântica ecoregion are given. Numbers refer to conservation units (1) Itabaiana National Park, (2) Baía de Todos os Santos Environmental Protection Area (EPA), (3) Caminhos Ecológicos da Boa Esperança EPA, (4) Pratigi EPA and (5) Baía de Camamu EPA.

Tab. 1
Morphometric data of Hyphessobrycon itaparicensis (n =108), including holotype, 16 paratypes, and 91 non-type specimens; and H. sergipanus (n=11), including holotype (obtained from Bragança et al., 2015Bragança PHN, Ottoni FP, Rangel-Pereira FS. Hyphessobrycon ellisae, a new species from northeastern Brazil (Teleostei: Characidae). Ichthyol Explor Freshwaters. 2015; 26 (3):255-62.) and 10 examined paratypes. Ranges of H. sergipanus do not include holotype. SD = standard deviation. Asterisk in percents of head length of H. sergipanus indicates the exact numbers given in the original description, with possible erroneous measurement of the upper jaw length.
