FIGURE 1. The phylogenetic tree of the genus Tetrapyrgos was generated using maximum likelihood (ML) and Bayesian inference (BI) analysis based on nrITS sequence data. ML bootstrap value ≥ 80% and BI posterior probabilities ≥ 0.90 are presented at relevant nodes as BS/PP. Metacampanella subdendrophora, M. costaricensis, and M. sinecystidia were used as the outgroup. The new taxon is in red. Type species are in bold text.
