ABSTRACT
The phylogenetic comparison of 440 characters in 87 genera representing all the 32 extant catfish families resulted in the almost completely resolved strict consensus cladogram illustrated in Fig. 3.123, with a length of 902 steps, Consistency Index (Cl) = 0.52 and Retention Index (RI) = 0.78. The indexes of
this consensus cladogram are thus significantly superior to those of Mo (1991: cladogram I: Cl = 0.34, RI = 0.64; cladogram II: Cl = 0.36, RI = 0.72) and de Pinna (1993: Cl = 0.41, RI = 0.72). The consensus cladogram of this work is more resolved than those of de Pinna's excellent 1993 work and of Mo's 1991 study: it presents only three trichotomies, of which only one directly concerns interfamilial relationships within Siluriformes (see below).
