Etymology: kunzei: The name kunzei is in honour of Eduardo Kunze Bastos, author of an unpublished dissertation written in 1979 comprising a pioneering study on the ecology of Rivulus punctatus from central Brazil, providing initial stimulus for studying taxonomy of the killyfishes today placed in the genus Melanorivulus (Ref. 92338).

簡短描述
型態特徵 | 形態測量圖
Distinguished from all other species of Melanorivulus, except M. kayapo, by having a colour pattern of flank in males consisting of irregular horizontal rows of red dots arranged to form a red reticulate pattern on the posterior part of flank, including canal peduncle region (vs. never a similar colour pattern; usually oblique red bars on the flank, reticulated areas when present are symmetrical and derived from overlapping bars). M. kunzei is distinguished from by having fewer caudal-fin rays (29-30 vs. 32-34), more neuromasts in the infraorbital series (1 + 11 + 1 vs. 1 + 7-9 + 1), and by the presence of dark grey dots on the subdistal portion of dorsal fin and middle of caudal fin in males (vs. absence) and small red spots on the caudal fin in males (vs. horizontally elongated red spots)(Ref. 92338).
