脊椎骨: 30. Diagnosed uniquely from its congeners by the reduction or absence of azygous plates in front of the nuchal plate. Differs further from its congeners by the presence of a minute lateral cusp in the teeth, wider body, anterior and lateral profile of head rounded, broad distal profile of the paired fins, and lower number of vertebrae (Ref. 56057).
独特地在颈背的碟之前从它的同类鉴定了藉由减少或者缺乏非对偶的碟。 进一步不同于它的同类藉由在齿,较宽的身体有一个细小的侧面尖头, 头部的前面而侧面轮廓圆形的, 偶鳍的宽末梢部轮廓 , 与脊椎骨的低数字.(参考文献 56057)
Known from stony piedmont tributaries of the left bank of Rio Paraíba do Sul.
