简单描述 型态特徵 | 形态测量图

This species is distinguished from all its congeners, except J. darwini, J. onca, J. sanctaecatarinae, J. maculata, J. luxata, by having a colour pattern of round or dash-shaped marks forming multiple rows; differs from J. onca and J. sanctaecatarinae by having the swelling between the urogenital opening and the base of the anal fin of females (vs. no swelling); differs from J. onca by not having a distinct dorsal convex expansion at subdistal segments of the right hemitrich of anal-fin ray six of adult males (vs. presence); differs from J. maculata with left and right halves of anal-fin ray six laterally paired in adult males (vs. not laterally paired); differs from J. luxata with medial processes of left and right pelvic bones overlapping at the ventral midline (vs. reduced processes not overlapping); differs from J. darwini by the dorsal postcleithrum being less than twice as deep as wide (vs. three times deeper than wide) and the female colour pattern in the half of the caudal peduncle with rows of aligned spots forming lines (vs. segmented in unaligned spots) (Ref. 128887).
鳍无色的。 身体的底色是橄榄色灰色与侧面显示六到八条深色又细的线或有点的纵向斑纹; 下面颜色较淡。 雄性超过雌性是重要地更细长而小的。 两性几乎展现相同的颜色。 未受精的在被位于的臀鳍上或在右边或左边上母鱼有一个橘色-色彩斑点.(参考文献 26130)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00614 - 0.02465), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
营养阶层 (Ref. 69278):  2.9   ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  中等的, 族群倍增时间最少 1.4 - 4.4年 (Fec=10-60; gestation usually lasts 6 weeks; tm=1; K=1.04-2.46).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
