Dorsal soft rays (total): 11-11; Vertebrae: 35-36. Differs from all other species of the genus, except Jupiaba acanthogaster,
Jupiaba atypindi, Jupiaba keithi, Jupiaba maroniensis, Jupiaba meunieri, Jupiaba minor and Jupiaba pinnata, in having teeth cusps of similar size and dentary teeth gradually decreasing in size posteriorly. Can be diagnosed from the aforementioned species, except Jupiaba meunieri, by its color pattern consisting of dark dots on the base of the majority of lateral body scales, inconspicuous dark elongated humeral blotch and well-marked dark round blotch on the caudal peduncle. Can be further distinguished from Jupiaba meunieri, as well as Jupiaba maroniensis, by having the following characters: scale series between lateral line and pelvic-fin origin 5-6 (vs. 6.5-7.5), anal fin with 21-24 branched rays (vs. 25-31), body depth at dorsal-fin origin 33.3-40.2 %, mean 36.3 % of SL (vs. 42.7-47.9 %, mean 45.5 % of SL, based on examined specimens) (Ref. 80698).
Description: Dorsal-fin rays ii, 9; Anal-fin rays iv or v, 21, 22, 23, or 24; Pectoral-fin rays i, 11, 12,
13 or 14; Pelvic-fin rays i, 7. Gill-rakers on first gill arch six or seven on epibranchial, one on cartilage between ceratobranchial and epibranchial, nine on ceratobranchial, and two on
hypobranchial (Ref. 80698). |
