Etymology: Notoglanidium: Greek, noton = back + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish; diminutive (Ref. 45335); pembetadi: The species name pembetadi refers to the local Kunyi name with 'tadi' meaning stone; based on some brief inquiries the meaning of 'pembe' remains unclear (Ref. 94483). Although the etymology has not been fully elucidated its Kunyi name seems to refer to the habitat where it lives, i.e., the large rocks and pebbles covering the bottom of the Kouilou-Niari River at Pont du Niari; the name was chosen to acknowledge that many of the new species discovered are already well known by the local inhabitants, and to express gratitude to the many children and fishermen who helped to collect the type series of this new species for science (Ref. 94483).

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 10 - 13; Anal spines: 0; Anal soft rays: 12 - 17; Vertebrae: 39 - 43. Diagnosis: Notoglanidium pembetadi differs from other species in the genus in having: a small predorsal body depth, 8.2-11.6% of standard length vs. larger in N. akiri, N. macrostoma, N. maculatum, N. thomasi and N. walkeri; a large horizontal distance between the bases of the anal and caudal fins, 15.7-18.6% of standard length vs. smaller in N. boutchangai, N. depierrei, N. macrostoma and N. maculatum; a small interorbital distance, 17.4-24.0% of head length vs. larger in N. akiri, N. macrostoma, N. maculatum, N. thomasi and N. walkeri; an average combined premaxillary tooth plate width, 20.8-26.4% of head length vs. larger in N. boutchangai and N. macrostoma, and smaller in N. maculatum, N. pallidum, N. thomasi and N. walkeri; and an average number of soft dorsal-fin rays, 10-13 vs. 7 rays in N. akiri, N. boutchangai and N. macrostoma, and 16-20 rays in N. maculatum (Ref. 94168, 94483).
It is found between large rocks and pebbles covering the bottom of the Kouilou-Niari River at Pont du Niari (Ref. 94483).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [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.

Trophic level (Ref.
69278): 3.5 ±0.6 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.).
Fishing Vulnerability (Ref.
