Etymology: Hasemania: Because of John D. Haseman, the American collector of fishes (Ref. 45335); negodagua: From Nego D'áqua, a legendary, manlike creature from Central Brazil, said to dwell in the bottom of rivers and attack inattentive fishermen at night. Noun in apposition.
Eponymy: John Diederich Haseman (1882–1969) was a zoologist and ichthyologist. [...] Nego D’água is a creature of Brazilian legend. He is said to be man-like, with webbed hands and feet. He sometimes attacks inattentive fishermen at night, or overturns canoes if the fishermen don’t give him a fish. (Ref. 128868), visit book page.

deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 2; duri punggung lunak (Keseluruhan (total)) : 8 - 9; Duri dubur: 4; Sirip dubur lunak: 14 - 17; vertebrata, bertulang belakang: 29 - 32. Distinguished from most Hyphessobrycon species (except H. taurocephalus) by the absence of an adipose fin (versus presence); and by the unique, possibly autapomorphic color pattern of mature males, which consists of a high concentration of dark chromatophores, mainly on the posterior part of the body, behind a vertical through the anal-fin origin, and the white color of the distal portions of the anal and dorsal fins.
