Abstract. Hyphessobrycon nigricinctus sp. n. – a new Characid fish (Teleostei: Characiformes: Characidae) is described from the drainage of the río Madre de Dios in Peru. The new species is a member of the H.-heterorhabdus-group and differs from all other species of this group by (1) a relatively deep body (depth 2.65–3.00 times in SL), (2) seven to eight scales above the lateral line, (3) a narrow, long maxilla with six to eight conical to tricuspid teeth, reaching up to the pupil, (4) anal fin with 22 to 26 branched fin rays, (5) males with hooklets in the distal part of anterior fin rays, (6) 33–34 scales in a longitudinal line, (7) lateral line relatively short, with seven pored scales. The colour in live is also characteristic: (8) a deep black lateral band from the gill cover to the end of middle caudal fin rays on two scales, (9) adipose deep red, (10) upper part of the iris also deep red and (11) a remarkable sexualdichromatism (males with especially deep red margins of anal, caudal, dorsal and pelvic fins, females without red fin margins).

這是一個發表於2004年, 近似紅尾幽靈燈(Hyphessobrycon loretoensis)的物種, 另請參見practicalfishkeeping的解說, zakkycharacin以及minifishe.de之圖片, 這條魚的體型有一點點像所謂的紅翅夢幻藍帝燈
