Figure 5 in The Victoria Falls, a species boundary for the Zambezi Parrotfish, Cyphomyrus discorhynchus (Peters, 1852), and the resurrection of Cyphomyrus cubangoensis (Pellegrin, 1936) (Mormyridae: Teleostei)

Figure 5. (A) Principal components analysis and discriminant function analysis on correlations for morphological characters in Cyphomyrus discorhynchus species complex. (A) Green stars, specimens from type locality, the Lower Zambezi at Tete (n = 4); Blue Z symbols, from Lower Zambezi at Marromeu (n = 19); red Y symbols, from Upper Zambezi (n = 33). Data set included all 19 characters of Table A2. (B) Green triangles, specimens from Middle Zambezi (Batoka Gorge, n = 35); blue Z symbols, from Lower Zambezi at Marromeu (n = 19); red Y symbols, from Upper Zambezi (n = 36). Data set included 15 rather than 19 characters, the non-separating characters (PAL/SL, LA/SL, pD/SL, CPL/SL) excluded by stepwise variable selection. (C) Red diamonds, specimens from Kwando River (n = 11); blue Z symbols, from Lower Zambezi at Marromeu (n = 19); green Y symbols, from Upper Zambezi (n = 36). Data set included 18 rather than 19 characters (SPc excluded). (D) Red X symbols, specimens from Okavango River (n = 21); blue Z symbols, from Lower Zambezi at Marromeu (n = 19); green Y symbols, from Upper Zambezi (n = 36). Data set included 17 rather than 19 characters (PAL/SL, PD/SL excluded). (E) Red X symbols, specimens from Okavango River (n = 21); blue-green Z symbols, from Lower Zambezi at Marromeu (n = 19); blue Y symbols, from Upper Zambezi (n = 33); orange triangles, from Middle Zambezi (n = 35); green diamonds, from Kwando River (n = 10). Data set included all 19 characters of Table A2. [This figure can be viewed in colour online].
