Identity and locality
Guyanancistrus nassauensis Mol, Fisch-Muller & Covain, 2018
Paramaka Creek and tributaries, Nassau Mountains, Suriname
Diagnostic evidence and naming
The 2018 PLOS integrative taxonomy paper distinguishes very small adult specimens with four branched anal rays, broad mouth and tooth cups. Restricted small-stream distribution raises mining conservation concerns. The 2018 original description and a specialist catalog independently list the Nassau Mountains, Suriname type locality; no captive pedigree or F1/F2 genetics is established.
Breeding and genetics limitations
No public aquarium genetics, first breeder or stable pattern morph is documented by original type-series specimens.
