Etymology: Jupiaba: An indigenous word from Brazil, in the region where Angela (Ichthyologist) was born and discovered several new fishes.

简单描述

背的软条 (总数) : 11; 臀鳍软条: 24 - 28; 脊椎骨: 35. Distinguished from its congeners by the presence of an unpigmented, horizontally-oriented, roughly oval area on the proximal portion of the caudal-fin lobes, bordered posteriorly by dark pigmentation (Ref. 54762).
与它的同类区分藉由有没有颜色, 水平地-在后部地被深色颜色毗邻的尾鳍叶的近端部分上的导向又概略椭圆形的区域.(参考文献 54762)
描述: 背鳍鳍条 ii,9; 臀鳍棘条 iv 或 v,20,21,22, 23 或 24; 胸鳍鳍条 i,11, 12 或 13; 腹鳍鳍条 i,7.(参考文献 54762)
Collected exclusively by seining beaches in pools immediately downstream of waterfalls or rapids, but not in the rapids themselves (Ref. 54762). Apparently avoids small forest streams (Ref. 54762). Feeds on filamentous algae, fragments of Podostemaceae, terrestrial and aquatic Hemipterans, adults and larvae of Trichopterans and odonate nymphs (Ref. 54762).
专门地收集藉由紧邻在水池中以曳网围捕海滩瀑布或急流顺流而下, 但是不在急流中他们自己.(参考文献 54762) 显然地避开小的森林溪流。 (参考文献 54762) 吃菌丝藻，川苔草的碎片，毛翅目昆虫与蜻蜓目昆虫蛹的陆生与水生半翅目昆虫，成鱼与仔鱼。 (参考文献 54762)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00577 - 0.02877), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

营养阶层 (Ref.
69278): 2.9 ±0.33 se; based on food items.
回复力 (Ref.
