Figure 8 from: Betters MJ, Cordes EE (2024) New records of Provanna (Gastropoda, Provannidae) from the Costa Rica Margin and an identification key for the genus. ZooKeys 1189: 1-32. https://doi.org/10.3897/zookeys.1189.109734

Figure 8 Bayesian phylogenetic tree of Provanna based on a 452 bp region of the mitochondrial CO1 gene. Novel sequences are bolded and highlighted in yellow. Topology was inferred using the HKY+G+I substitution model. Numbers above branch nodes represent Bayesian posterior probabilities. Numbers below branch nodes represent the proportion of replicate trees in which the associated taxa clustered together in the bootstrap test (10,000 replicates). Only values above 50 are shown. The tree is drawn to scale, with branch lengths representing the number of base substitutions accumulated over time.
