Species Information
Size	176mm or 6.9" SL. Find near, nearer or same sized spp.
Identification	Pseudancistrus is the only genus of the Ancistrini (former Ancistrinae) that lacks evertible cheek plates. Because of this characteristic, it has at times been placed in the Hypostominae. Pseudancistrus sidereus is diagnosed by a unique modification of the ventral plates on the caudal peduncle. In loricariids, the plates of the ventral row on the caudal peduncle are typically bent at an approximately 90° angle to follow the contour of the body. The bend is often the site of a slight keel formed from one or more rows of slightly longer odontodes. In P. sidereus, the keel is accentuated by having the dorsal laminae of the plates strongly concave. Although some loricariids may have the dorsal laminae slightly concave, it is much more pronounced in P. sidereus.
