Etymology: Mazarunia: Taken from river Mazaruni; local habitat of this fish (Ref. 45335); pala: The specific name is from the Greek pala, meaning gold nugget. This is in reference to the golden spots behind and under the orbit and also to the fact that this species has only been collected in the main channel of the upper Mazaruni River, where a growing gold mining industry may be contributing to degradation of its habitat. To be regarded as an adjective in feminine form.
Eponymy: This is a toponym referring to the Mazaruni river system in Guyana. (Ref. 128868), visit book page.

Épines dorsales (Total) : 15 - 17; Rayons mous dorsaux (Total) : 7 - 8; Épines anales: 3; Rayons mous anaux: 7; Vertèbres: 26. Based on phylogenetic analysis, this species is distinguished from its congeners by the derived absence of a parhypurapophysis (132-1). Based on external characters, it is diagnosable by the presence of a dorsal-fin scaly pad with ctenoid scales (vs. no scaly pad in Mazarunia charadrica and Mazarunia mazarunii), a small suborbital stripe that is limited to the preopercle, by the absence of clearly discernible lateral bars on the body, and by its general pinkish coloration with a midlateral spot as the only melanic marking (Ref. 91746).
Occurs mostly in or near the main upper Mazaruni River channel in localities with sandy or slightly muddy substrates with structure formed by submerged or emerging grass and other
riparian vegetation and some drift wood. Appears to move at night into shallow, flooded banks with terrestrial vegetation (Ref. 91746).
