Identity and locality
Ancistrus maldonadoi Bifi & Ortega, 2020
Río Madre de Dios basin, Manu and tributaries, Peru
Diagnostic evidence and naming
Original 2020 paper distinguished maldonadoi from greeni by larger eye, deeper caudal peduncle and longer adipose spine while retaining uncommon unicuspid teeth shared by both species. The specialist catalog confirms the 2020 Ancistrus maldonadoi type in Rio Salvacion of Peru's Madre de Dios drainage. The uncommon single-cusped teeth shared with A. greeni and measurable head-eye differences distinguish the taxa, not selectively bred grades.
Breeding and genetics limitations
Do not market random common bristlenose as maldonadoi: original taxonomic differences require measurement, not a color morph guess.
