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.

Morphology | Morphometrics
Jupiaba citrina is distinguished from its
congeners (except J. abramoides (Eigenmann), J. anteroides, and J. poranga Zanata) by its color pattern, consisting of two 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. The new species 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 caudalfin rays by a clear area). Jupiaba citrina differs from various congeners (except J. abramoides, J. anteroides, J. apenima, J. asymmetrica (Eigenmann), J. poranga, and J. yarina Zanata), by having the predorsal median area without a series
of scales (vs. predorsal median area with a series of organized scales). Jupiaba citrina differs further from J. poranga and
also J. yarina by its lower number of perforated scales (47-51 vs. 56-66) and 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). From J. apenima it differs also by having lower number of perforated scales (47-51 vs. 55-59). The new species can be additionally distinguished from part of its congeners (J. acanthogaster, J. atypindi Zanata, J. keithi (Géry et al.), J.
maroniensis (Géry et al.), J. meunieri (Géry et al.), J. kurua
Birindelli et al., J. minor (Travassos), J. pinnata (Eigenmann), and J. poekotero Zanata & Lima) 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). From the remaining species, J. citrina differs further from J. iasy (Netto-
Ferreira et al.), J. mucronata (Eigenmann), J. ocellata (Géry
et al.), J. paranatinga (Netto-Ferreira et al.), J. pirana Zanata, J. polylepis, J. potaroensis (Eigenmann), and J. zonata by having higher number of perforated scales (47-51 vs. 33-45), and from J. elassonaktis Pereira & Lucinda, J. essequibensis (Eigenmann), and J. scologaster (Weitzman & Vari) by having
higher number of branched anal-fin rays (24-27 vs. 17-23 (Ref. 83383).
