3.2. Phylogenetic relationships
Phylogenies inferred from both tandem amino acid sequences and DNA
sequences of the 12 mt protein-encoding genes demonstrated that T.
caixuepengi in a monophyletic group with T. pisiformis andT. laticollis , with the closest genetic relative being T.
pisiformis ; T. tianguangfui was also found in a monophyletic
group with T. crassiceps , T. twitchelli and T.
martis , and has the far genetic relative with T. caixuepengi(Fig. 2).
