Abstract

The osteological characters of Silurus microdorsalis were described and compaired with its related species, S. asotus. S. microdorsalis differ from S. asotus based on the sharp narrowness of ethmoid width, having cartilagenous rib in weverian apparatus and inside saw-teeth of pectoral spine, presence of distal radial cartilage of dorsal and pectoral fin and that of sphenotic process, 4 branched fin rays of pectoral, ventral and dorsal fin, 2 pterygiophore of dorsal fin, 7 rakers, 50-58 vertebrae, 12 branchiostegal rays and fin formulae.
