Hyphessobrycon brumado: a new characid fish (Ostariophysi: Characiformes) from the upper rio de Contas drainage, Chapada Diamantina, Bahia, Brazil

Abstract

Hyphessobrycon brumado: a new characid fish (Ostariophysi: Characiformes) from the upper rio de Contas drainage, Chapada Diamantina, Bahia, Brazil Angela M. Zanata and Priscila Camelier A new species of Hyphessobrycon Ellis is described from tributaries of the upper rio de Contas, Bahia, Brazil. The new species can be diagnosed from its congeners by having low body depth, a broad black stripe along lateral of body that extends weakly through median caudal-fin rays, absence of humeral spot and orange-to reddish life coloration. Uma espécie nova de Hyphessobrycon Ellis é descrita de afluentes do alto rio de Contas, Bahia, Brasil. A espécie nova pode ser diagnosticada de suas congêneres por ter corpo baixo, uma faixa escura larga na lateral do corpo que se estende fracamente pelos raios medianos caudais, ausência de mancha umeral e coloração alaranjada a avermelhada em vida.

Redescription and osteology of Hyphessobrycon compressus (Meek) (Teleostei: Characidae), type species of the genus

“…Color patterns have been suggested convey a phylogenetic signal among recently described species of Hyphessobrycon (e.g., Bertaco et al, 2007;Benine & Lopes, 2008;Zanata & Camelier, 2010;Ingenito et al, 2013;Dagosta et al, 2014;Lima et al, 2014). One pattern was proposed as a putative synapomorphy for part of Hyphessobrycon (the "rosy tetra clade", Weitzman & Palmer, 1997) including H. compressus.…”

A new species of Hyphessobrycon Durbin (Characiformes: Characidae) from the middle rio São Francisco and upper and middle rio Tocantins basins, Brazil, with comments on its biogeographic history

“…Hyphessobrycon diastatos is distinguished from these species by having 15-18 (mode: 16) branched analfin rays (vs. 17-22, mode: 19) and absence of sexually dimorphic elongation of pelvic fin in males (vs. presence). Zanata & Camelier (2010) proposed a putative close relationship among Hyphessobrycon brumado, H. negodagua, and H. parvellus on the basis mainly of a reduced muscle layer between the first and second ribs, the absence of humeral spot, and the sexually dimorphic caudal spot. Males of the aforementioned species have a poorly-defined caudalpeduncle, formed by pigmentation spread over inner portions of the caudal lobes (especially in H. negodagua and H. parvellus, Fig.…”

Development of secondary sexual characters and their relationship to ontogeny and seasonal reproductive period in Hyphessobrycon igneus (Ostariophysi: Characiformes)

“…Adult male and female fin colour is another form of sexual dimorphism in H. igneus . In Hyphessobrycon more generally, fin colour variation has been observed in the species H. bifasciatus , wherein both caudal and anal‐fins are red in young, but are lemon‐yellow in adults (Oyakawa et al, ); in Hyphessobrycon brumado Zanata & Camelier, and Hyphessobrycon negodagua Lima & Gerhard 2001 , males and females differ in the colour of the caudal region (Zanata & Camelier, ). Sexual differences in colour pattern have been reported for other Characidae species.…”
