Phylogenetic analysis of H. tianjinensis with other species of Hirudo A maximum-likelihood tree was constructed using MEGA 7 with 1000 ML bootstrap replications B bayesian inference tree was constructed using MrBayes with four Markov chains. Chain length was set as 1,500,000 generations and sampled every 1000 generations.
