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

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 11; 臀鰭軟條: 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).
與它的同類區分藉由有沒有顏色, 水平地-在後部地被深色顏色毗鄰的尾鰭葉的近端部分上的導向又概略橢圓形的區域.(參考文獻 54762)
描述: 背鰭鰭條 ii,9; 臀鰭棘條 iv 或 v,20,21,22,23 或 24; 胸鰭鰭條 i,11,12 或 13; 腹鰭鰭條 i,7.(參考文獻 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).
緊鄰專門地被在水池的圍網海灘收集瀑布或急流順流而下, 但是不在急流中他們自己.(參考文獻 54762) 顯然地避開小的森林溪流。 (參考文獻 54762) 吃菌絲藻，川苔草的碎片，毛翅目昆蟲與蜻蜓目昆蟲蛹的陸生與水生半翅目昆蟲，成魚與仔魚。 (參考文獻 54762)
