Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); macropunctatus: The specific epiteth is a combination of the Greek 'makros', meaning large, and the Latin 'punctata', meaning spotted, a reference to the large spots that characterize the coloration pattern of this species (Ref. 75786).
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal. Tropical
Africa: Uamba River (Kwango drainage) and southern tributaries of the Kasai (middle Congo River basin) in Angola (Ref. 11970, 75786).

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines: 4 - 5; Anal soft rays: 8 - 9. Length of the maxillary barbel 37.2-48.5% of standard length and 138.2-176.3% of head length; length of lateral mandibular barbel 87.2-107.9% of head length; length of medial mandibular barbel 38.5-54.5% of head length (Ref. 75786). Number of mandibular teeth 27-35 (Ref. 75786). Humeral process triangular, granulous; possessing poorly developed ridge on ventral margin; dorsal margin concave to slightly convex in largest specimens, with 0-2 small, pointed projections; terminating in sharp point (Ref. 75786).
Colour: In preservation, dorsum pale to dark brown, covered with large dark spots; ventral areas light with dark spots; maxillary and mandibular barbels light brown; Dorsal en pectoral-fin spines brownish, filaments dark; all fins light brown with large dark spots (Ref. 75786).
Prefers deeper water near river banks (Ref. 11970). Nothing is known about the diet, reproductive behavior, or abundance of this species (Ref. 75786).

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=0.01549 (0.00700 - 0.03427), b=2.88 (2.70 - 3.06), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.3 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 (18 of 100).
