Etymology: Hyphessobrycon: Greek, hyphesson, -on, -on = a little smaller + Greek, bryko = to bite (Ref. 45335); weitzmanorum: The specific name honors Stanley and Marilyn Weitzman, for their life-long interest and extensive coontributions to the knowledge of Neotropical freshwater fishes. Including are several papers adressing the systematics of Hyphessobrycon and related.

脊椎骨: 32 - 33. Hyphessobrycon weitzmanorum is distinguished from all congeners, except H. tortuguerae Böhlke, H. bifasciatus Ellis, H. savagei Bussing, H. flammeus Myers, H. griemi Hoedeman, H. balbus Myers, H. itaparicensis Lima & Costa, and H. columbianus Zarske & Géry, by possessing two humeral spots. H. weitzmanorum is distinguished from H. bifasciatus, H. savagei, H. flammeus, H. tortuguerae, H. griemi, H. itaparicensis, and H. columbianus by possessing a general dark color pattern, due to a high concentration of dark chromatophores uniformly distributed over the lateral surfaces of the body (vs. a general clear color pattern, with few, scattered chromatophores over the lateral surfaces of the body). Additionally, Hyphessobrycon weitzmanorum differs from H. bifasciatus, H. griemi and H. tortuguerae by possessing two intensely pigmented, vertically-elongate humeral spots (vs. second humeral blotch fainter in H. bifasciatus; first humeral blotch fainter in H. griemi; and both humeral blotches small, not vertically-elongate in H. tortuguerae). Hyphessobrycon weitzmanorum is distinguished from H. flammeus and H. savagei by possessing wide humeral blotches, with somewhat rounded margins (vs. humeral blotches narrow, with straight margins). Hyphessobrycon weitzmanorum is distinguished from H. balbus in possessing 5 -9 perforated lateral line scales (vs. 11 - 22) and in having the second humeral blotch intensely pigmented (vs. very faint). Hyphessobrycon weitzmanorum is distinguished from H. itaparicensis Lima & Costa (2001), by possessing a lower number of branched anal-fin rays (17 - 21, vs. 22 - 25) and lack of a midlateral, horizontal stripe, crimson in life, that extends from the vertical just posterior of the dorsal-fin origin to the caudal peduncle. Hyphessobrycon weitzmanorum is distinguished from H. columbianus Zarske & Géry (2002), by possessing a lower number of branched anal-fin rays (17 - 21, vs. 23 - 24) and orange pigmentation in life on the caudal, anal, dorsal and pelvic fins (vs. red pigmentation on caudal, and anal) (Ref. 52338).
Hyphessobrycon weitzmanorum 被与所有的同类区分, 除了 <之外i>H. tortuguerae Bohlke, H. bifasciatus 埃利斯, H. savagei Bussing, H. flammeus 我的, H. griemi Hoedeman, H. balbus 我的, H. itaparicensis 利马 &肋骨, 与 H. columbianus Zarske&Gery, 藉由持有二個肩部的斑點。 H. weitzmanorum 被區分的 H. bifasciatus, H. savagei, H. flammeus, H. tortuguerae, H. griemi, H. itaparicensis, 與 H. columbianus 藉由持有一個一般的深色彩色斑紋, 由於佈滿均勻的身體的側面表面的高濃度的深色色素胞.(vs. 一個一般的清澈彩色斑紋, 有些, 在身體的側面表面上的分散色素胞) 附加地， Hyphessobrycon weitzmanorum 藉由持有有別於 H. bifasciatus, H. griemi 與 H. tortuguerae 二顏色濃密, 細長垂直的肩部斑點 (vs. 比較模糊的第二個肩部斑塊在 H. bifasciatus; 第一個肩部斑塊比較模糊的在 H. griemi 中; 而且兩者的肩部斑塊小的, 不是細長垂直在 H. tortuguerae 中). Hyphessobrycon weitzmanorum 被藉由持有寬的肩部斑塊與 H. flammeus 與 H. savagei 區分, 與略微圓形的邊緣。 (vs. 肩部斑塊狹窄的, 有直的邊緣) Hyphessobrycon weitzmanorum 在持有 5-9個穿孔的側線鱗片方面被與 H. balbus 區分 (vs.11- 22) 而且有第二個肩部斑塊顏色濃密.(vs. 非常模糊的) Hyphessobrycon weitzmanorum 被與 H. itaparicensis 利馬 & 肋骨 (2001) 區分, 藉由持有一個分枝臀鰭棘條的低數字 (17- 21, vs.22- 25) 而且沒有一條側面中央又水平的斑紋, 變為深紅色活著時, 那延伸從垂直的正好對尾梗的背鰭起源後面。 Hyphessobrycon weitzmanorum 被與 H. columbianus Zarske& Gery(2002) 區分, 藉由持有一個分枝臀鰭棘條的低數字 (17- 21, vs.23- 24) 而且橘色的顏色活著時在尾鰭上, 肛門的, 背部的與腹鰭 (vs. 紅色的顏色尾部的之上, 與肛門的).(參考文獻 52338)
