背鰭 (合計): 11; 臀鰭: 19 - 22; 脊つい: 32 - 33. Diagnosis: Hyphessobrycon natagaima differs from all other species of Hyphessobrycon with a dark lateral stripe that inhabit the Magdalena River Basin, H. poecilioides, H. proteus and H. ocasoensis, by the number of pored lateral-line scales (8 to 12 vs. 14-26); the number of scales between lateral line and pelvic-fin insertion (4 vs. 5 or 6), the number of teeth on the maxilla (1 vs. 0 in H. poecilioides, and 2 to 5 in H. proteus; except H. ocasoensis, which also has 1); a dark, interrupted lateral stripe that is not in contact with the caudal peduncle spot (vs. absence of caudal spot in H. poecilioides, lateral stripe continued that is in contact with the caudal peduncle spot in H. ocasoensis); a rhomboid shaped caudal-peduncle spot that continues on to middle caudal-fin rays (vs. absence of caudal peduncle spot in H. poecilioides and caudal peduncle spot round and not continued on to middle caudal-fin rays in H. ocasoensis); and presence of hooks on all fins in mature males (vs. males with hooks on anal, pelvic and pectoral fins); Hyphessobrycon natagaima differs from H. ocasoensis in addition to the characters mentions above by having 4 scale rows between lateral line and anal-fin origin (vs. 6); 3 or 4, mode 4 scale rows between the lateral line and the pelvic-fin insertions (vs. 6); 10 or 11, mode 11 predorsal scales (vs. 9); the number of dorsal-fin rays (i,9,i vs. ii,8,i); 18-20, mode 20 branched anal-fin rays (vs. 21-22, mode 22), and 11 branched pectoral-fin rays (vs. 12)(Ref. 118120).
