Etymology: Otopharynx: Greek, ous = hear + Greek, pharyngx = pharynx (Ref. 45335); pachycheilus: Named after the thick lip, the character that first made this species immediately recognizable as a unique three-spotted taxon (Ref. 40031).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; depth range 125 - 135 m (Ref. 58018). Tropical
Africa: Lake Malawi (Ref. 40031).

Morphology | Morphometrics
(total): 15 - 17;
soft rays: 8 - 10. Body relatively deep; head large (Ref. 40031). Jaws isognathous (Ref. 40031). Lips greatly enlarged (Ref. 40031, 54524), soft, and deeply folded back onto snout and lower jaw (Ref. 40031). Premaxillary pedicel not prominent (Ref. 40031). Teeth in outer rows of upper and lower jaws bicuspid, relatively closely set (Ref. 40031). Pectoral fin relatively long, extending past base of third anal fin spine to base of seventh anal fin ray (Ref. 40031). Caudal fin scaled more than three quarters of fin length near dorsal and ventral edges (Ref. 40031).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00846 - 0.04293), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±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).
