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).
More on author: Regan.

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic. Tropical

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 15.2 cm SL male/unsexed; (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).

Biology     Glossary (e.g. epibenthic)

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).
