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);  pembetadi: 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 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 can be distinguished from all other species in Notoglanidium and Anaspidoglanis by the following unique combination of characters: a premaxillary toothplate of horseshoe-like shape and a combined toothplate width of 20.8-26.4% of head length, vs. cardiform and narrower and 11.1-15.3% of head length in N. pallidum, 11.9-18.2% of head length in N. thomasi and 13.7-16.1% of head length in N. walkeri, vs. crescent-like and wider and 30.1-35.3% of head length in A. boutchangai and 33.5-41.7% of head length in A. macrostoma, vs. rectangular but similar in width, 22.0-26.1% of head length, in A. akiri (Ref. 94483). Notoglanidium pembetadi can be further distinguished from all Notoglanidium species by the following unique combination of measurements: a short head length, being 21.1-22.8% of standard length vs. 27.8-29.5% of standard length in N. pallidum, 24.1-27.0% of standard length in N. thomasi and 25.3-28.9% of standard length in N. walkeri; and a short dorsal-fin base length, being 21.0-24.4% of standard length, vs. longer, 18.4-22.4 in N. pallidum and 29.3-34.1% of standard length in N. thomasi (Ref. 94483). Notoglanidium pembetadi can be further distinguished from all Anaspidoglanis species by the following unique combination of characters: a high number of dorsal-fin rays, II, 10-13 vs. II, 7; a long dorsal-fin base length being 21.1-24.4% of standard length vs. 13.9-20.1%; a short predorsal distance being 30.1-33.5% of standard length, vs. 36.3-44.4%; and a short prepelvic distance being 40.1-45.4% of standard length, vs. 46.6-58.2% (Ref. 94483).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 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. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (21 of 100) .
