IUCN Red List

Pareiorhaphis steindachneri is distributed in the Cubatão, Itapocu, and Itajaí-Açu river basins in the states of Paraná and Santa Catarina. It is a frequent and abundant species that inhabits fast-flowing, well-oxygenated, cold waters with rocky substrates and preserved vegetation cover. In parts of its range, there are threats such as deforestation, mining, and pollution from pesticides. However, these do not represent a risk of extinction for the population. The species occurs in several conservation units (e.g., Serra de Itajaí National Park). Therefore, no significant threats have been identified that would put its populations at risk of extinction. Thus, P. steindachneri was categorised as Least Concern (LC), (IUCN 2022).
