Figure 8 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 8. Canonical three-dimensional plot of discriminant function analysis on correlations for morphological characters in the Cyphomyrus discorhynchus species complex. Spheres show the 95% confidence region to contain true mean of group. Note spheres for the three populations of Okavango/Upper Zambezi system origin all together in the lower left; Lower/Middle Zambezi specimens shown as two separate spheres, suggestive of geographic differentiation (the sphere on the far right, and the uppermost sphere). Blue -green Z symbols, from Lower Zambezi at Marromeu (n = 19); orange triangles, from Middle Zambezi (n = 35); red X symbols, specimens from Okavango River (n = 21); blue Y symbols, from upper Zambezi (n = 33); green diamonds, from Kwando River (n = 10). Data set included all 19 characters of Table B2. [This figure can be viewed in colour online.]
