Identity and locality
Ancistrus amaris de Souza et al., 2019
Guiana Shield/Orinoco Andes study region; exact type stream pending
Diagnostic evidence and naming
Original 2019 revision groups this species with yutajae among wide-jawed forms; A. amaris has reduced male snout tentacles versus several congeners, not a selected domestic morph. The 2019 Guiana Shield / Orinoco revision described A. amaris; the specialist type record includes the Apure drainage in Venezuela. This is not a captive-selected phenotype.
