Pseudancistrus sidereus is a species of catfish belonging to the family Loricariidae. It is only known from the upper Orinoco basin in Amazonas state, Venezuela.
This is a fairly large loricariid (up to around 18 cm standard length), and is distinguished from its congeners by a strong keel on the caudal peduncle and the colour scheme which is generally very dark with bright white or yellow spots on the upperside.
