Abstract: Three new species of Hyphessobrycon (Characiformes: Characidae) are described from the upper rio Araguaia basin. Hyphessobrycon langeanii n. sp. is distinguished from all congeners by the presence of a well-defined, round humeral spot, a reticulate color pattern, a broad, horizontally-elongate caudal-peduncle blotch, and a relatively wide, faint midlateral dark stripe. Hyphessobrycon eilyos n. sp. is distinguished from all congeners by the absence of humeral and caudal spots; by the presence of numerous dark c… Show more

“…Measurements and counts follow Fink & Weitzman (1974), Lima & Moreira (2003), and Carvalho et al (2010). Measures were made with a caliper rule to the nearest 0.05 mm on the left side of the specimen whenever possible, and are presented as percents of standard length (SL) or head length (HL).…”

“…This pattern is shared with some specimens of H. weitzmaniorum Lima & Moreira (2003), an uncommon count for the genus or even for most characid species. This unusually character could suggest a close relationship between these taxa.…”

“…Much of the information used to distinguish species are probably labile features such as variations in color patterns, counts and corporal measurements, that may be little informative about phylogenetic relationships. Remarkably, some species of the genus present a great morphological diversity, as presented by Lima & Moreira (2003) in the description of a heterogeneous group of three new species. Géry (1977: 458-459), proposed six artificial groups of Hyphessobrycon species based on color pattern.…”

“…The Hyphessobrycon are allocated in the incertae sedis group of the Characidade family (Lima et al 2003) with more than 130 species (e.g., Lima and Moreira 2003, Carvalho and Bertaco 2006). Among these, a species known as “Mato Grosso” has been considered Hyphessobrycon callistus (Boulenger, 1900) for a long time, however with the revision of Weitzman and Palmer (1997), it started to be classified as Hyphessobrycon eques .…”
