Etymology: Bunocephalus: Greek, byneo = to fill up, to swell + Greek, kephale = head (Ref. 45335); minerim: The specific name, minerim, refers to the typically regional manner of pronouncing the Portuguese
word 'mineirinho', diminutive of 'mineiro', which pertains to a person that comes from the State of Minas Gerais. The name is in reference to the region where it is found and also to its relative small size in comparison with other species of Bunocephalus. A noun in apposition.

Morphology | Morphometrics
soft rays: 7 - 9;
Vertebrae: 34 - 37. Bunocephalus minerim is distinguished from all other species of Bunocephalus, except B. larai, by the absence of an epiphyseal bar between the paired frontals (vs. presence of the epiphyseal bar at least in adults). It differs from B. larai and other congeners, except B. chamaizelus, by having 9 principal caudal-fin rays (vs. 10) (Ref. 104710).
