Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 9; Raggi anali molli: 17 - 19. This species is distinguished from its congeners by the following characters: presence of iii,9 rays in the dorsal-fin (vs. ii,9); from most congeners by having 2 humeral spots, in which the first one is vertically elongate (except in M. diamantina, M. diktyota, M. eigenmanni, M. inrai, M. levidorsa, M. moisae, M. naponis, M. pankilopteryx, and M. surinamensis) (vs. absent, or horizontally elongate or diffuse humeral spot); differs from the remaining species by the number of branched anal-fin rays 17-19 (vs. 20-35); from M. diktyota, M. eigenmanni, M. georgiae, M. inrai, M. levidorsa, M. moisae, and M. naponis by the number of the lateral line scales, 36-37 (vs. 41-47 in M. moisae and 31-35 in the remaining species); from M. pankilopteryx by the number of maxillary teeth 4-5 (vs. 2-3) and the shape of the caudal peduncle spot which is vertically elongate (vs. horizontally elongate in M. pankilopteryx) (Ref. 86678).

Inhabits streams, occurs in semi-lentic and lotic shallow areas (up to 1.0 m deep) with riparian vegetation composed by trees and shrubs. The area of collection is around 800 m above sea level. The streams have transparent water; bottom with rocks, stones, and some stretches with sand; collected syntopically with Aspidoras albater, Astyanax sp., Characidium stigmosum, Corumbataia veadeiros, Hemigrammus tocantinsi, and Trichomycterus sp. Stomach contents (UFRGS 11194, 3:24.4-27.3 mm SL) were mainly composed by Hymenoptera, Coleoptera (adults) and some fish scales, but autochthonous insects and digested vegetal organic matter (seeds) were also found (Ref. 86678).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01202 (0.00517 - 0.02796), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
