Catarina Rato, D. James Harris, Salvador Carranza, Luís Machado, Ana Perera. Molecular Phylogenetics and Evolution. September, 2015. Bayesian clustering analysis supports all six mtDNA lineages as independent groups, despite showing signs of ancestral polymorphism or possibly gene flow between the Maghreb/South Iberia and Central Morocco clades. The species tree recovered two major groups; one clustering taxa from Europe and Northern Maghreb and another one encompassing the lineages from Central/Southern Morocco, Central Morocco and Canary Islands, indicating that the ancestor of T. angustimentalis came from the Central/Southern Morocco region. Finally, Bayesian coalescent species delimitation analysis supports all six mitochondrial clades as “unconfirmed candidate species”, pending morphological data to define them. Leer más.
