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).
在所有大小的标本中的腹部上全部没有小板; 而且用达不到吻部的嘴边缘的前面者的前缘藉着具有在范围方面被缩小的嘴的碟, 没有腹的屈曲.(参考文献 47265) 进一步在腹部上用裸露区与其他的 Parotocinclus 种区分藉着具有 25-29个中央的碟而且藉着具有只在两边上的小区域上被暴露的肩带.(参考文献 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).
发现于被密集的长廊森林包围的清澈水域小溪,与底部岩石，小圆石与沙子组成, 藉由水中枯枝落叶只有在更大与更深的水池的底部。 用沙子的独自地被组成的难得杂草丛与底部也生活于较大的水体中。 吃硅藻，蓝绿藻，绿藻与有机物。 (参考文献 47265)
