Maximum Likelihood Tree of 32 COI sequences of Trachysphaera and outgroup specimens. Rate model: discrete Gamma distribution, 5 categories (+G, parameter = 0.7759); nucleotide frequencies: A / T = 0.3273, C / G = 0.1727; tree is drawn to scale, branch lengths reflect number of substitutions per site; 1st, 2nd, 3rd codon positions and non-coding positions were included, gaps and missing data excluded; node values = 1000 replicates ML bootstrap support.
