Relevant Information:

The export of this large species is very rare as they have not been caught in any great numbers. It is classed as endangered in its natural habitat. The main threats to its existence are the construction of dams, riparian habitat destruction, water pollution and fishing. Description: Pectoral, adipose and pelvic fins small sized; pelvic fin short, never reaching anus; color pattern combining dark brown lines with large dark brown dots on dorsum of head and trunk; 15-17 gill-rakers on first branchial arch. Etymology: The specific name parahybae: From the Rio Parahyba, Brazil. Remarks: The first specimen is a juvenile captured in Pirassununga, São Paulo State, Brazil in 2010. The second specimen was photographed by the image contributor in CESP Aquaculture Station, Paraibuna, São Paulo State in 2009.

IUCN Red List

Steindachneridion parahybae originally occurred throughout the Paraíba do Sul River basin, in the states of São Paulo, Rio de Janeiro, and Minas Gerais. It is a rare and scarce species, closely associated with rocky areas in pools near rapids. The area of occupancy (AOO) calculated based on confirmed localities of occurrence of the species is 28 km². The various dams in the Paraíba do Sul River basin cause severe fragmentation of the population, since individuals do not inhabit the reservoirs. The dams are responsible for altering or eliminating the lotic environments occupied by this species, which, together with siltation and domestic and industrial pollution, promote the continued decline of the area of occupancy, extent, and quality of the habitat. Thus, S. parahybae was listed in the Endangered (EN) category, (IUCN 2021).
