Identity and locality
Hopliancistrus tricornis Isbrücker & Nijssen, 1989
Middle Rio Tapajós / São Luiz rapids, Brazil
Diagnostic evidence and naming
2021 genus revision explicitly connects L212 to tricornis; it has four branched anal-fin rays and comparatively large pale trunk spots, unlike Xingu H. wolverine with five anal-fin rays and fine yellow dots. The specialist catalog confirms historic L212 for Hopliancistrus tricornis, originally described in 1989, rather than a novel taxon introduced in the 2021 phylogenetic revision.
Breeding and genetics limitations
Do not reuse broad Wolverine L017 advice for L212, whose species, watershed and habitat differ.
