Phylogenetic relationships within the flatworm genus Matuxia (Platyhelminthes, Tricladida, Continenticola) inferred from molecular data with the description of a southern lineage of the genus

The genus Matuxia Carbayo et al., 2013 currently comprises two species with distribution restricted to southeastern Brazil. In the present study, based on an integrative approach, we examine the genetic diversity within the genus and describe a new species, Matuxia tymbyra Rossi and Leal-Zanchet, sp. nov., representing a southern lineage of the genus. We employed one mitochondrial (cytochrome c oxidase subunit I, COI) and other nuclear...
