Cat-eLog Data Sheet
Scientific Name	**Pseudancistrus pectegenitor** Lujan, Armbruster & Sabaj, 2007
Common Name(s)	L261
Type Locality	Venezuela, Amazonas: Rio Casiquaire, bedrock in stream 73 km NE of San Carlos de Rio Negro (2 21' 09''N 66 34' 31''W)
Etymology	Greek, pseudes = false + Greek, agkistron = hook or barb. "False Ancistrus", meaning that it is like an Ancistrus, but yet not quite. This specific epithet refers to the hypertrophied odontodes (pecten=quill) of the snout, pectoral spine and evertible cheek plates plus the fact that one adult male was presumably collected while caring(genitor=father) for a large brood of young.
Species Information
Size	242mm (9.5") 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.
Sexing	Males possess greatly elongated evertible cheek odontodes as well as slightly elongated odontodes on the pectoral spines and snout.
Habitat Information
