Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 6; Anale zachte stralen: 11 - 12. This species is distinguished from its congeners by the following characters: with a wide brown stripe in the dorsal and caudal fins in specimens larger than 2.5 cm SL (inconspicuous or absent in small specimens) and by the presence of neuromasts surrounded by melanophores forming small black dots aligned in four rows on head, one on nape, one posterior to nape, and three horizontal on trunk; differs further by the presence or absence of a light band on nape (some paratypes have a small and irregular pale brown blotch on the region nuchal), supraoccipital process not contacting the anterior nuchal plate, width of mouth 34-47% HL (vs. 47-63 in M. carlae, M. cibelae, M. cottoides, M. iheringi, M. malabarbai, M. minutus, M. reikoae, M. nigripinnis, M. oliveirai, M. parahybae, M. pataxo, M. pleriqueater, M. sparsus, M. variegatus), and greater caudal peduncle length 15.9-17.9% SL (vs. 10.0-15.9 in M. carlae, M. cibelae, M. cottoides, M. eurystoma, M. iheringi, M. maculatus, M. malabarbai, M. nigripinnis, M. parahybae, M. pataxo, M. pellopterygius, M. poecilus, M. secundus, M. variegatus) (Ref. 130492).
The specimens of were collected from small watercourses draining the Cerrado biome, with riparian forest relatively well preserved and usually with buriti palm trees (Mauritia flexuosa) present on the margins of the stream and around these watercourses, there are usually livestock pastures. At the córrego Narciso, there are small rapids, sandy patches, and pools, usually presenting leaves, fallen tree branches, and submerged leaf-litter at the bottom (Ref. 130492).

Estimates based on models
Fylogenetische diversiteitsindex (Ref. 82804): PD50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00314 - 0.01747), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
