Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Siluriformes (Catfishes) > 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).

Short description Identification keys | 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00221 - 0.01248), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.59 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (24 of 100).
