Scientific Name Pseudancistrus pectegenitor  Lujan, Armbruster & Sabaj, 2007
Common Name 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.
