FIGURE 6 in Cathorops festae (Boulenger 1898) (Siluriformes; Ariidae), a valid species from Ecuador and Peru
FIGURE 6. Scatterplots of the principal components PC1 and PC2, obtained from the analysis of eleven morphometric and one meristic variables, with factor loadings for the first and second principal components. Abbreviations: Cathorops festae (FE = holotype, fe = non-type specimens), C. manglarensis (MA = holotype, ma = paratypes, PE = specimen from Peru), and C. multiradiatus (MU = neotype, mu = non-type specimens), EC = holotype of Tachysurus equatorialis.
FIGURE 5. A in Cathorops festae (Boulenger 1898) (Siluriformes; Ariidae), a valid species from Ecuador and Peru
FIGURE 5. A, Cathorops clade extracted from the Ariidae tree of Betancur-R. et al. (2012), including one individual of C. festae (shown in bold). The complete time tree was estimated using a Bayesian analysis of five mitochondrial and six nuclear gene fragments and 19 calibration points (both inside and outside Ariidae). B, RAxML tree estimated with expanded specimen sampling for Cathorops (including two individuals of C. festae, shown in bold), but based on the analysis of only two mitochondrial genes (Cyt b and ATPase 8/6). Nodal numbers indicate bootstrap support values. Two letter country codes follow ISO-3166.
