Abstract EN
Four Synodontis, ف’, schcill (Bloch-Schineider, 1801), ث', serrants (Ruppel, 1829), s.
frontosus (Vaillant, 1895) 1اسم s.
nig/'it،( (Cuvier and Valenciennes, 1840), were chosen for réévaluation of the classical morphological identification.
The shape of the ا،إ'اءاااااآا process was found to he sufficient to distinguish each species.
The marginal membranes along the maxillary bai'bels.
and the serration ol'نأآ1ا dorsal spine were clear diagnostic features of s.
serratus.
!)٦ addition to external features, morphometl'ic measurements were treated numerically, as ratios to standard length and head length (indices), to standardize the methods o؛’ fish discrimination and correct for size differences of these species.
The index of dorsal-to-adipose fin (DAD) can easily distinguish s.
nigrita.
The number of pectoral fin rays (TER), gill rakers (GR), and vertebrae (VR) proved to be useful for species discrimination.
Verification of the taxonomy ol' the gentis Synodontis ()١؛ biochemical and genetic basis is suggested
