La morfometria de los espermatozoides descrita por primera vez en el presente trabajo, sigue el patron general reportado en los caracidos: Boehlkea fredcochui, Bryconacidnus ellisi, Bryconamericus exodon, Ceratobranchia obtusirostris, Cyanocharax alburnus, Creagrutus meridionalis, Knodus meridae, Odontostoechus lethostigmus, Piabina anhembi, Piabina argentea, Rhinobrycon negrensis (BaicereSilva et al, 2011); Hemigrammus marginatus (Magalhaes et al, 2011); Piaractus mesopotamicus y Serrasalmus maculatus (Gusmao-Pompiani et al, 2009) ya que la estructura esta determinada por el modo de reproduccion, tamano de los ovocitos producidos por las hembras y nivel sistematico en que se encuentran las especies (Jemieson, 1991).
A phylogenetic reconstruction is needed that includes the type species to begin to unravel the phylogenetic relationships of the species of Hyphessobrycon sensu lato, the group to which Hyphessobrycon natagaima belongs, and to determine the limits of Hemigrammus.
1998) reported a similar feeding habit for Cichla orinocensis Humboldt, 1821 in Guri Reservoir, which foraged mostly in shallow, structured habitats within littoral zone where Crenicichla wallacii Regan, 1905, other cichlids, and the characid Hemigrammus micropterus Meek, 1907 were the dominant preys.

The seven species of small-sized fish species that coexisted in the nine ponds included in this study were: Astyanax altiparanae (Garutti; Britski, 2000) (28-106 mm SL); Astyanax jasciatus (Cuvier, 1819) (38-76 mm SL); Bryconamericus stramineus Eigenmann 1908 (18-45 mm SL); Hemigrammus marginatus Ellis, 1911 (23-49 mm SL); Hyphessobrycon eques (Steindachner, 1882) (12-34 mm SL); Moenkhausia intermedia Eigenmann, 1908 (19-68 mm SL) and Moenkhausia sanctaefilomenae (Steindachner, 1907) (14-46 mm SL).
These macrohabitats shared 37 species comprising the largest assemblage of ornamental and relatively smaller species (<120mm standard length), such as those in the Astyanax, Ancistrus, Apareiodon, Apistogramma, Bujurquina, Characidium, Cheirodon, Corydoras, Hemigrammus, Holoshesthes, Moenkhausia, Otocinclus, Odontostilbe and Xenurobrycon genera.
The photos show two males with the longest dorsal rays dark and prolonged, probably reaching adipose if depressed, a probably vertical humeral spot followed by a light zone, and a caudal spot beginning above the last fourth of the anal fin and continuing on the lower part of the peduncle then onto the middle of the fin up to the tip of the middle caudal fin rays, with a light spot on the upper part of the peduncle and on the base of the lobes, a pattern ressembling that of Hemigrammus hyanuag or Hemigrammus haraLA for example.
La definicion actual del genero Hyphessobrycon (Durbin en Eigenmann 1908) es ambigua ya que se basa en caracteres plesiomorficos presentes en otros generos relacionados como Hemigrammus, Parapristella, Astyanax, Moenkhausia, entre otros (Garcia-Alzate 2009).
