Phylogenetic relationships within Ninia inferred using a Bayesian inference and derived from analysis of DNA gene fragments 16S, CYTB, ND4, and RAG1. Support values on intra-specific branches are not shown for clarity. Voucher numbers for sequences are indicated for each terminal. Black dots indicate clades with posterior probability values from 95–100%. Grey dots indicate values from 70–94%. White dots indicate values from 50–69% (values <50% not shown). Colored clades correspond to the species’ distribution presented in Fig. 2.
