Identity and locality
Pseudancistrus barbatus (Valenciennes, 1840)
La Mana River, French Guiana (type locality); further Guiana Shield occurrence records
Diagnostic evidence and naming
The named P. barbatus anchors the Pseudancistrus barbatus group. The 2014 revision compares its hypertrophied snout odontodes with Tapajós P. zawadzkii and Guyana Shield relatives. The specialist taxon account names La Mana River in French Guiana as the type locality; broader populations do not establish one captive lineage.
Breeding and genetics limitations
Do not assume this is an Ancistrus bristlenose or that whiskered snout is a domesticated trait. Captive original breeder unknown.
