Fig. 1. Phylogenetic tree based on the nuclear 18S rRNA gene (592 nt), ArgK (677 nt), and the mitochondrial COI gene (603 nt). Bootstrap values for maximum likelihood conducted in IQTrees and posterior probabilities for Bayesian inferences conducted in MrBayes were mapped onto the best scoring ML tree. The scale bar denotes three substitutions per one hundred nucleotide positions.
