Phylogenetic relationships within Dipsadini derived from analysis of 3,375 bp of DNA (gene fragments 12S, 16S, Cytb, ND4 and c-mos). Support values on intraspecic branches are not shown for clarity. Voucher numbers for sequences are indicated for each terminal when available. a Maximum likelihood analysis. Black dots indicate clades with bootstrap values from 90–100%. Grey dots indicate values from 70–89%. White dots indicate values from 50–69% (values <50% not shown) b Bayesian inference analysis. 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).
