The ray-finned fish

This species reaches a length of 10.4 centimetres (4.1 in) SL.

Range and habitat

It is endemic to Brazil and can be found in the Tapajós and Xingu River basins. This species appears similar to members of Lasiancistrus, however it lacks the synapomorphies and has five rows of plates on the caudal peduncle instead of three like those found in Lasiancistrus. The International Union for Conservation of Nature have assessed this species as Endangered because half of its known range has been affected, or will be affected, by the construction of dams.
