Five Independent Lineages Revealed by Integrative Taxonomy in the Dendropsophus nanus–Dendropsophus walfordi Species Complex

One of the many taxonomic challenges found in the Dendropsophus microcephalus species group is the Dendropsophus walfordi distinction from D. nanus. Recent phylogenetic inferences have indicated the paraphyly of these species, although they we...
