Etymology: Tylochromis: Greek, tylos = callus + Greek, chromis = a fish, perhaps a perch (Ref. 45335); microdon: Named by Regan (1920) presumably in reference to the fine pharyngeal dentition of the species (Ref. 52346).

Africa: Lake Tumba (middle Congo River basin) in Democratic Republic of the Congo (Ref. 52307, 52346). Report from Lake Mai-Ndombe questionable, possibly an error in locality designation (Ref. 52346).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 12 - 15; Anal soft rays: 7; Vertebrae: 28 - 29. Diagnosis: marked hypertrophy of lateral line canals on flank and caudal fin; inflated preopercular laterosensory canals; distinctive excavation of premaxillary oral valve (Ref. 52346).

Restricted in its distribution to the lake proper and absent from the surrounding swamps and inundated forest (Ref. 52346). Predominantly a lacustrine form (unusual among Tylochromines)(Ref. 52346). Benthic microphage (Ref. 52346). Feeds mainly upon small organic particles, plants and invertebrates; maternal mouthbrooder that does not pair bond (Ref. 52307).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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): 2.8 ±0.32 se; based on food items.

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).
