Etymology: Notoglanidium: Greek, noton = back + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish; diminutive (Ref. 45335); boutchangai: Named in honour of H. Boutchanga, collector of the type specimens (Ref. 94168).
Eponymy: Honoré Boutchanga was a Gabonese technical assistant, Eaux et Forêts (Waters and Forests). He collected the holotype. (Ref. 128868), visit book page.

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 2; Raggi dorsali molli (totale) : 7; Spine anali: 0; Raggi anali molli: 14 - 17; Vertebre: 40. Diagnosis: combined premaxillary tooth plate width rather large, 30.1-35.3% of head length vs. larger in N. macrostoma and smaller in N. akiri, N. pembetadi and much smaller in the other species except N. depierrei; interorbital distance small, 17.2-23.4% of head length vs. larger in N. akiri and over 27% in N. macrostoma, M. maculatum, N. thomasi and N. walkeri; eye diameter relatively large, 7.5-10.4% of head length, negatively allometric with body size, vs. smaller in N. pallidum and N. maculatum; only 7 soft dorsal-fin rays vs. more than 8 in N. depierrei, N. maculatum, N. pallidum, N. pembetadi, N. thomasi and N. walkeri (Ref. 94168).
Body shape (shape guide): elongated.

Inhabits rivers (Ref. 27938).

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00218 - 0.01265), b=3.09 (2.88 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Fonte Biblio. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Fonte Biblio. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100). 🛈
