This monotypic genus is known from the lower Paraná River basin. Ecological and behavioral data are unavailable. This genus is interesting in many respects. It shares features with representatives of different groups within Loricariini . For example, it possesses conspicuous fringed barbels on the lower lip, a feature shared by the representatives of the Pseudohemiodon ^ZBK group. It also bears numerous papillae on the inner surfaces of the lips and numerous straight bicuspid teeth (approx. 15 per premaxillae) that are characteristic of the Rineloricaria ^ZBK group.
