Identity and locality
Guyanancistrus megastictus Fisch-Muller, Mol & Covain, 2018
Crique Alama, Upper Maroni basin, French Guiana
Diagnostic evidence and naming
Only two original described specimens from small tributary in Mitaraka mountains, with very large pale spots and a strong light caudal bar; molecular sequence and anatomy support distinction. A specialist catalog confirms the Crique Alama, Maroni basin, French Guiana type locality, not a captive breeder origin.
