FIGURE 1 in Integrative taxonomy of Imparfinis (Siluriformes, Heptapteridae) from the Upper Paraná River basin, Brazil, with description of a new species
FIGURE 1. Map of samples sites (a) and maximum likelihood three of COI data (b). Black bars represent the molecular criteria used to species delimitation. Black nodes indicate>90% bootstrap values from 1.000 pseudoreplicates; grey nodes indicate support between 70% and 90% bootstrap values. Colored symbols in the map and in the tree represent the species (Imparfinis lepturus—pink star; I. minutus—yellow diamond; Imparfinis mirini—blue circle; I. piperatus—light blue triangle; Imparfinis n.sp.—black hexagon and I. schubarti—red square). Topotype samples represented by asterisc.
