Identity and locality
Chaetostoma sacramento Meza-Vargas, Ramírez & Lujan, 2024
Aguaytía, Pisqui and Palcazú tributaries, Ucayali drainage, Peru
Diagnostic evidence and naming
The 2024 original scientific description consolidates the historical L455, L456 and L457 appearances into one named species. White irregular spots or vermiculations on head and body, two predorsal plates and COI/Cytb evidence help distinguish it from related Chaetostoma. The specialist catalog groups historical L455, L456 and L457 under the one 2024-described Chaetostoma sacramento; no separate inherited color lines are demonstrated.
Breeding and genetics limitations
Three hobby color codes do not prove three separate Mendelian color morphs, strains or captive founders. No reproductive genetics shown by species delimitation.
