Etymology: Mastacembelus: Greek, mastax, -agos = bite + Greek, emballo = to throw oneself (Ref. 45335); tinwini: Named for U Tin Win, in appreciation of his help in the field and the gift of specimens..
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical

Morphology | Morphometrics
(total): 36 - 39;
soft rays: 63 - 73;
Vertebrae: 89 - 93. Differs from all congeners by having a unique color pattern consisting of five regular and parallel, black, longitudinal bands along the body, frequently expressed a series of interrupted lines or broken up into individuals blotches, and a white margin to the soft dorsal, anal, and caudal fins. Can be separated from other members of the Mastacembelus armatus group by having 41-43 + 47-51 = 89-92 vertebrae (Ref. 78150).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00127 - 0.00572), b=2.95 (2.76 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (36 of 100).
