Etymology: Jupiaba: An indigenous word from Brazil, in the region where Angela (Ichthyologist) was born and discovered several new fishes. (Personal communication from Barry Chernoff, Curator Fishes/Museum of Chicago; citrina: From the Latin citrus, meaning lemon, orange, in allusion to the orange-yellowish coloration of body portions of the species in life..

Descrição suscinta
Morfologia | Morfometria
This species is distinguished from its congeners (except J. abramoides, J. anteroides, and J. poranga by its color pattern, with 2 vertically-elongated humeral blotches, the anterior usually with a darker median portion forming an horizontally elongated trace pointed anteriorly, and a well defined dark longitudinal line extending from the second humeral blotch to the caudal peduncle; differs from J. abramoides, J. anteroides, and J. poranga by having an horizontally-elongated blotch on caudal peduncle that extends continuously to the distal tip of the caudal-fin median rays (vs. dark line not forming blotch on caudal peduncle and posterior end of this line isolated from dark blotch over caudal fin rays by a clear area); differs from various congeners (except J. abramoides, J. anteroides, J. apenima, J. asymmetrica, J. poranga, and J. yarina), by having the predorsal median area without a series of scales (vs. with a series of organized scales); differs further from J. poranga and J. yarina by its lower number of perforated scales (47-51 vs. 56-66) and the lower number of scales between dorsal-fin origin and lateral line 10-11 (one specimen with 12) vs. 12-15] and between lateral line and origin of pelvic fin (8-9 vs. 10-13); differs from J. apenima by having lower number of perforated scales (47-51 vs. 55-59); additionally distinguished from part of its congeners (J. acanthogaster, J. atypindi, J. keithi, J. maroniensis, J. meunieri, J. kurua, J. minor, J. pinnata, and J. poekotero) by having teeth with a distinctly larger median cusp and dentary teeth decreasing abruptly in size posteriorly (vs. median teeth cusp similar in size to the remaining cusps and dentary teeth decreasing gradually in size towards posterior portion); differs from the remaining species, J. citrina and further from J. iasy, J. mucronata, J. ocellata, J. paranatinga, J. pirana, J. polylepis, J. potaroensis, and J. zonata by having higher number of perforated scales (47-51 vs. 33-45), and from J. elassonaktis, J. essequibensis, and J. scologaster by having higher number of branched anal-fin rays (24-27 vs. 17-23 (Ref. 83383).
