FIGURE 9. A in Taxonomic revision of the New World genus Ariopsis Gill (Siluriformes: Ariidae), with description of two new species

FIGURE 9. A, Clade including the genera Sciades + Potamarius + Ariopsis, extracted from the Ariidae tree of Betancur-R. et al. (2012), including five of the eight species of Ariopsis validated herein. 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, Rooted RAxML phylogram with expanded specimen sampling for six species of Ariopsis, but based on the analysis of only two mitochondrial genes (Cyt b and ATPase 8/6; 1937 bp). Nodal numbers indicate RAxML bootstrap support values and posterior probability values (MrBayes tree), respectively. The RAxML and MrBayes trees are identical with respect to topology and highly similar with respect to branch lengths. Two letter country codes follow ISO-3166.
