Figure 7 in Two new catfish species of typically Amazonian lineages in the Upper Rio Paraguay (Aspredinidae: Hoplomyzontinae and Trichomycteridae: Vandelliinae), with a biogeographic discussion

Figure 7. Ancestral geographic reconstruction from Aspredinidae using BBM (7A) and S-DIVA (7B) and from the MTSVG clade of Trichomycteridae using S-DIVA (7C) and BBM (7D). Biogeographical regions: A = Amazon-core; B = São Francisco and Eastern Coastal drainages; C = Paraná-Paraguay; D = Trans-Andean. Black arrows indicate biotic dispersal from Amazon-core to Paraná-Paraguay region. See Materials and Methods section for further analytic details.
