Abstract: A new miniature species of Hyphessobrycon is described from an affluent of the Rio Papagaio, tributary of the Rio Juruena, upper Rio Tapajós basin, Mato Grosso State, Brazil. The new species can be distinguished from its congeners by having a remarkable secondary sexual dimorphism in its live colouration (males are red and females yellow), well-defined and relatively narrow dark midlateral stripe extending from tip of snout to tip of middle caudal-fin rays, absence of humeral blotch, 15-18 branched anal-fin ra… Show more

“…Among fishes, sexual selection is responsible for the evolution of impressive morphological novelties. Specifically in the Characiformes, secondary sexual dimorphism is commonly associated to the occurrence of bony hooks on fins, breeding tubercles, gill glands, modified scales [2–10], shape and length of the dorsal, pelvic and anal fins [1121], and sexual dichromatism [22,23].…”

“…In certain fish species, sex is a morphological criterion to distinguish between male and female (sexual dimorphism) in aquaculture broodstock selection. In general, the character performance of males is more attractive than females (Camelier et al, 2018;Kottler & Schartl, 2018). This research showed that %LRCC and %ARCC values in males were higher than that of females (P<0.05) (Table 3).…”

“…As discussed by Camelier et al . (2018), although the aforementioned subgroups help in the identification of such a species‐rich genus, potential homologies based on coloration pattern need to be evaluated in a phylogenetic framework. The relationships of H. chiribiquete among congeners is still undetermined and will probably remain so until a study based on DNA sequences can be performed.…”
