Total absence of platelets on the abdomen in specimens of all sizes; and by having rostral plates reduced in extent with anterior margins that fall short of the anterior of the rostral margin of the snout, lacking a ventral curvature (Ref. 47265). Further distinguished from other Parotocinclus species with naked areas on the abdomen by having 25-29 median plates and by having the pectoral girdle exposed only on small areas on each side (Ref. 47265).
在所有大小的標本中的腹部上全部沒有小板; 而且用達不到吻部的嘴邊緣的前面者的前緣藉著具有在範圍方面被縮小的嘴的碟, 沒有腹的屈曲.(參考文獻 47265) 進一步在腹部上用裸露區與其他的 Parotocinclus 種區分藉著具有 25-29個中央的碟而且藉著具有只在兩邊上的小區域上被暴露的肩帶.(參考文獻 47265)
Facultative air-breathing in the genus (Ref. 126274); Found in clear water creeks surrounded by dense gallery forest, with bottom composed of rocks, pebbles and sand, with submerged litter only at the bottoms of the larger and deeper pools. Also occurs in larger water bodies with scarce marginal vegetation and the substrate composed solely of sand. Feeds on diatoms, cyanobacteria, green algae and organic matter (Ref. 47265).
發現於被密集的長廊森林包圍的清澈水域小溪,與底部岩石，小圓石與沙子組成, 藉由水中枯枝落葉只有在更大與更深的水池的底部。 用沙子的獨自地被組成的難得雜草叢與底部也生活於較大的水體中。 吃矽藻，藍綠藻，綠藻與有機物。 (參考文獻 47265)
