Figure 4 in Integrative taxonomy clarifies the armoured catfish Hypostomus pusarum (Starks) species complex (Siluriformes: Loricariidae) and reveals a new species in the drainages of Northeastern Brazil

Figure 4. Maximum likelihood tree with phylogenetic relationships of the Hypostomus pusarum complex and Hypostomus aff. pusarum. Ŋe tree is associated with the occurrence of populations. On the right, a haplotype network for the COI molecular marker of the species of the H. pusarum complex and Hypostomus aff. pusarum. Each circle represents a haplotype and the size of the circles is proportional to the number of individuals that have the haplotype. Black dashes between circles indicate mutational steps. Abbreviations of the hydrographic basins: Ceará* Mirim (CEA), Jaguaribe (JAG), Granjeiro (GÞ), Choró (CHO), Trairí (TÞ), Salgado (SAL), São Francisco (SFR) and Parnaíba (PNB). Ecoregion abbreviations: north*east Caatinga and Coastal Drainage (NCCD), São Francisco (SAFR) and Parnaíba (PNBA).
