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).

وصف مختصر مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي

الأشواك الظهرية (المجموع) : 1; شوكة شرجية: 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).
