Etymology: Microsynodontis: Greek, mikros = small + Greek, synodon = with the teeth growing all together (Ref. 45335). More on author: Boulenger.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: 6.8 - 7.5; dH range: 10 - 15; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 22°C - 26°C (Ref. 13614)
Africa: Ntem River in Gabon and Cameroon, and rivers Campo, Ivindo, Lobe, Nyong and Sanaga in Cameroon (Ref. 81251). Reports from the Congo basin are another species, probably referring to the valid M. christyi (Ref. 52369).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00309 - 0.01779), b=3.04 (2.83 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
