Costa et al. 2022 (3) Ivan Sazima (1)

Habitat: Marimbondo River, tributary of the Preto River, Paraíba do Sul River basin (Costa et al. 2022). Diet: Will feed on most aquarium fare such as tablet, frozen and live foods. It is an opportunistic predator that mainly feeds on insects, but also will take small crustaceans and plant material (algae and remains of phanerogams). Etymology: The specific name auroguttatus: aureus (L.), golden; guttatus (L.), spotted, referring to golden spots (alternating with dark spots) on posterior half of body, and a row of gold spots on midline of back, behind dorsal-fin base. Remarks: Trichomycterus auroguttatus is endemic to the Paraíba do Sul basin, being rare and not very abundant. It occurs in an area impacted by urbanisation, which apparently does not represent a significant threat that puts its population at risk, being categorised as Least Concern (LC) (IUCN 2018).
