Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335); punu: Named after the Punu people living in the Ngounié, the Nyanga (souther Gabon) and the Niari provinces (Republic of Congo), which is approximately the area where the species was collected. Collecting expeditions are always, somehow, the result of human col.

Short description
Morfologia | Morfometria
Spine dorsali (totale): 2; Raggi dorsali molli (totale): 6-7; Spine anali 3-4; Raggi anali molli: 7 - 8. A small species of Synodontis; body, at base of pectoral fins broader than high; dorsal profile of snout steep sloping until about vertical through posterior margin of orbit where-upon profile of head more gentle; complete lateral line, curving slightly dorsally above level of humeral process, further posteriorly straight, gently declining towards middle of caudal-fin base; head large (Ref. 82554).
Synodontis punu is distinguished from its Lower Guinea congeners by the following unique combination of characters: posterior border of operculum with a single hypertrophied opercular spine in sexually mature males, and caudal fin with a pair of black patches, one on the upper and one on the lower lobe (vs. both characters absent in all other Lower Guinea species except S. acanthoperca) (Ref. 82554).

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 ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
