Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 2; Mjukstrålar i ryggfenan (totalt): 9; Taggstrålar i analfenan 4; Mjukstrålar i analfenan: 20 - 22; Ryggkotor: 33. Color pattern on body reticulated, formed by dark pigmentation along the posterior portion of the scales. A horizontally elongate black stripe extends from a vertical through the last anal fin ray to tips of middle caudal fin rays. The caudal peduncle stripe is not preceded by a light area as that on M. oligolepis. The anterior humeral blotch is uniformly pigmented along its length. Lateral line incomplete (Ref. 41101).

50 = 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).
Trofisk nivå (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resiliens (Ref.
