Species delimitation

We follow a multi-criteria approach to delimitation incorporating phylogenetic trees, genetic distance, geography and morphology. We employ a comprehensive field sampling approach taking into account the heterogeneity of the landscape which allows us to identify sister lineages with confidence.
