“…Curiously, Hyphessobrycon taurocephalus, described in the same paper and also lacking an adipose fin, was not included in Hasemania. Intraspecific variation of this character within the genus was reported for Hyphessobrycon negodagua (adipose fin present in four specimens, absent in 158 according to Lima & Gerhard, 2001), H. eilyos (present in 163 specimens, absent in 52 according to , H. uaiso Carvalho & Langeani (adipose fin variably developed in 512 specimens, absent in 1 specimen, according to Carvalho & Langeani, 2013) and H. langeanii Lima & Moreira (adipose fin always present but vestigial in some specimens according to . Such intraspecific variation of adipose fin was also observed by Géry (1977) in Hasemania nana (Lütken) and by the present authors (present in 3, absent in 173 specimens; MZUSP 38040).…”

“…Hyphessobrycon Durbin is one of the most species-rich genera of the Characidae, comprising approximately 130 valid species (Carvalho & Langeani, 2013;García-Alzate et al, 2013a, 2013bIngenito et al, 2013). The genus is distributed from Southern Mexico to the rio de La Plata in Argentina, and most of its diversity occurs east of the Andes.…”

“…In "Material examined" catalog numbers are followed by the total number of specimens, number of specimens measured and counted in parentheses, and SL range of all specimens of the lot (including c&s specimens, if any), when possible. Comparative material examined included also those material listed in Carvalho et al (2010), Carvalho & Langeani (2013), and Carvalho et al (2014). Institutional abbreviations followed Reis et al (2003), with the addition of UFRGS -Departamento de Zoologia, Universidade Federal do Rio Grande do Sul, Porto Alegre.…”
