Type Locality Doutsila River at Bihongo, 2°48.312'S, 11°45.970'E, Nyanga River basin, Republic of Congo.

Etymology According to Cuvier, Synodontis is an "ancient name for an undetermined fish from the Nile". It is apparently not derived, as often reported, from syn-, together and odous, tooth, presumed etymology of the lizardfish genus Synodus and in reference to the closely-spaced lower jaw teeth of both genera. The species is dedicated to the Punu people, inhabitants of the area, in appreciation for their help during collecting in the area and in gratitude for their spontaneous hospitality.

Size 44mm or 1.7" SL. Find near, nearer or same sized spp.
Identification All species in the genus Synodontis have a hardened head cap that has attached a process (humeral process) which is situated behind the gill opening and pointed towards the posterior. The dorsal fin and pectoral fins have a hardened first ray which is serrated. Caudal fin is always forked. There is one pair of maxillary barbels, sometimes having membranes and occasionally branched. The two pairs of mandibular barbels are often branched and can have nodes attached. The cone-shaped teeth in the upper jaw are short. S-shaped and movable in the lower jaw. These fish produce audible sounds when disturbed rubbing the base of the pectoral spine against the pectoral girdle.

Synodontis punu is distinguised from its congeners except (S. acanthoperca) by having a hypertrophied opercular spine in sexually mature males and a caudal fin with a pair of black patches, one on the upper and one on the lower lobe. This species can be differentiated from S.acanthoperca by the absence of a saddle-like dark brown spot situated posterior to the dorsal fin and anterior to the adipose fin. Also has a deeper, triangular humeral process.
Sexing Hypertrophied opercular spine in mature males.
