Blunt-toothed African catfish

Dorsal spines (total): 0; Dorsal soft rays (total): 56-62; Anal spines: 0; Anal soft rays: 50-58; Vertebrae: 56-60. Diagnosis: Characterized by a relatively long vomerine tooth plate (5.9-14.4% of head length) and by a relatively short adipose fin (5.9-12.5% of standard length), the length of which is a specific character of Clarias ngamensis; head oval to rectangular in dorsal outline; frontal fontanelle long and narrow (`knife-shaped'); occipital fontanelle small and oval-shaped; pectoral spine robust and slightly curved; the suprabranchial organ consists of well developed arborescent structures (Ref. 248). It is distinguished from Clarias gariepinus by having a short adipose fin behind the rayed dorsal and an ovoid vomerine toothplate with granular or blunt teeth (Ref. 52193).
