Etymology: Atopodontus: Name from the Greek words 'atopos' meaning strange, anomalous or out of place, and 'odontos' meaning tooth. The name refers to the unusual mandibular dentition possessed by species of the genus.; adriaensi: The specific name is patronymic in honor of Dr. Dominique Adriaens, who brought the existence of this species to the authors attention (ref. 78584).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Africa: from rapids in the Ivindo, Okano, Ngounié, and Nyanga Rivers of Gabon (Ref. 78584).

Morphology | Morphometrics
soft rays: 4 - 7;
Vertebrae: 32 - 35. It has the presence of a free orbital margin, mandibular sensory canal pores on the lower lip/oral disc, a ventral process on the mesethmoid for articulation with premaxillae, a vertically-oriented, laminar extension of bone at the anterolateral edge of the lateral ethmoid that wraps around the extensor tentaculi muscle, 3 or more straight, transverse rows of mandibular teeth, a short, block-like autopalatine and the parapophyses of vertebrae 3, 4, and 5 of the Weberian apparatus are clearly separate from each other (Ref. 78584). Body compressed posteriorly and somewhat depressed anteriorly (Ref. 78584).

Phylogenetic diversity index (Ref. 82805
= 1.0000 [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
): 3.2 ±0.4 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.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
