Etymology: Labeo: Latin, labeo = one who has large lips (Ref. 45335); macrostoma: From the Greek macros meaning big, large and stoma meaning mouth (Ref. 12456).
More on author: Boulenger.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 0° - 10°S
Africa: lower Congo River basin in Democratic Republic of the Congo (Ref. 26192). Also reported from Stanley-Pool (Ref. 2801). Other reports (Cameroon, Kwango and Kasai rivers in Angola, Aruwimi, middle Congo River and Kasai in Congo DR) are questionable and need confirmation. Mostly in rapid water habitats, e.g. cataracts of Yelala and Kinsuka.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00312 - 0.01685), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (49 of 100).
