More on author: Roberts.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical
Africa: only known from the type locality in the Lokunje basin in south-eastern Cameroon (Ref. 13094, 81251).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 4.4 cm SL male/unsexed; (Ref. 13094)
Dorsal spines (total): 1; Dorsal soft rays (total): 4 - 5; Anal spines: 0; Vertebrae: 30 - 31. Diagnosis: sucker huge and rounded, longer than broad; mandibular barbels very small, no auxiliary mandibular barbels; premaxillary teeth large in up to 7 rows; mandibular teeth usually in 2 rows, with 13+13 to 15+15 teeth; eye very small; adipose fin long and low, its origin well in advance of a vertical through anal fin origin; caudal peduncle moderately deep; caudal fin moderately forked with lobes rounded, nearly equal; no sexual dimorphism of anal fin, caudal fin or humeral process of pectoral girdle (Ref. 81251).
Coloration: preserved specimens with numerous large melanophores more or less uniformly distributed over entire dorso-lateral surface of body, rapidly becoming sparser toward middle of abdomen; dark vertical bar on base of caudal fin as well as one in its middle (Ref. 81251).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
