Etymology: Stomatorhinus: Greek, stoma = mouth + Greek, rhinos = nose (Ref. 45335). More on author: Boulenger.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -
Africa: lower Congo (Ref. 1877, 1878, 41591) and Pool Malebo (Ref. 41585) in Democratic Republic of the Congo. Also in the Sangha (middle Congo River basin) in Cameroon (Ref. 46233). Also reported from the Chiloango (Ref. 1877), from where one of the four syntypes originates, although species not included in Ref. 81635. Report from the Rio Cuebe (Okavango basin) in Angola (Ref. 89016) questionable and needs verification.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.3 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 (10 of 100) .
