Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Actinopterygii (ray-finned fishes) > Siluriformes (Catfish) > Claroteidae (Claroteid catfishes) > Auchenoglanidinae
Etymology: Notoglanidium: Greek, noton = back + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish; diminutive (Ref. 45335);  macrostoma: From Greek, makros (big) and stoma (mouth), referring to the large mouth of the species (Ref. 94168). The species name macrostomus (Ref. 58032) is an unjustified emendation, as it is a compound noun and therefore must not agree in gender with the genus name (Ref. 98168).

Environment / Climate / Range Ecology

Freshwater; demersal; pH range: 6.5 - 8.0; dH range: 4 - 25.   Tropical; 23°C - 27°C (Ref. 1672); 5°N - 10°S

Africa: Lower Guinea river basins from Sanaga River in Cameroon to Chiloango River in Angola (Ref. 81642 94168), and also in the northern half of the Congo River basin (Ref. 94168), including Dja River in Cameroon (Ref. 27938), Sangha River in Congo Republic (Ref. 94168) and Middle Congo River basin in Democratic Republic of the Congo (Ref. 27938, 94168).

Maturity: Lm ?  range ? - ? cm

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7-8; Anal spines: 0; Anal soft rays: 10 - 12; Vertebrae: 38. Diagnosis: combined premaxillary tooth plate very broad, 33.5-41.7% of head length vs. 30.1-35.3% in N. boutchangai, and less than 30% in the other species; eye diameter large, 9.1-13.3% of head length vs. smaller in N. maculatum, N. pallidum and N. depierrei, but overlapping with eye size range of the other species; interorbital distance rather large, 28.0-36.6% of head length vs. 24.0% or less in N. akiri, N. depierrei, N. pallidum and N. pembetadi; only 7 soft dorsal-fin rays vs. more than 8 in N. depierrei, N. maculatum, N. pallidum, N. pembetadi, N. thomasi and N. walkeri; dorsal fin spine rather long, 6.9-14.7% of standard length vs. shorter in N. depierrei, N. maculatum, N. pembetadi and N. thomasi (Ref. 94168).
