Etymology: Synodontis: Greek, syn, symphysis = grown together + Greek, odous = teeth (Ref. 45335).
Issue
Reassigned to Synodontis based on a phylogenetic study by Vigliotta (2008: Ref. 79014). This species is placed in the genus Hemisynodontis in Eschmeyer (CofF ver. May 2011: Ref. 86870).

Maturity: Lm ?, range 25 - ? cm
Max length : 46.0 cm SL jantan/; (Ref. 57223)
Duri punggung (Keseluruhan (total)) : 1; Duri dubur: 0. Diagnosis: gill slits extending downwards beyond pelvic-fin insertions to the midline of isthmus; maxillary barbels not longer than head, lacking tubercles and ramifications, but with a broad, black membrane extending over their entire length; mandibular barbels with a broad black membrane; outer and inner mandibular barbels with few and simple ramifications, and membranous at tips; mandibular teeth short, numbering 8-16; pectoral-fin spines more strongly denticulate on inner than on outer margin; dorsal-fin spine smooth, except for weak serrations present on posterior margin in some specimens; humeral process deep, short, granular and not keeled ventrally; adipose fin high, long and contiguous to rayed dorsal fin (Ref. 57223).
Coloration: typically inverted colour, the back being uniformly whitish-grey and the belly black; fins greyish, without spots; maxillary and mandibular barbels (particularly the outer pair) bordered by a broad, black membrane (Ref. 57223).
Occurs in deep water close to the shore. Omnivore, feeds on plankton and detritus (Ref. 13868). May also feed on surface insects, chironomid larvae, benthic crustaceans, and mollusks (Ref. 28714). Oviparous (Ref. 205). Maximum size reported as 50.0cm (length type not given)(Ref. 31256).
