Characterization of the complete mitochondrial genome of Euwallacea fornicatus (Eichhoff, 1868) (Coleoptera: Curculionidae: Scolytinae) and its phylogenetic implications.

In the present report, we described the complete mitochondrial genome of Euwallacea fornicatus from Sindien, New Taipei City, Taiwan. The length of the complete mitogenome of E. fornicatus is 15,743 bp and the mitogenome contains 13 protein-coding, 22 tRNA and two rDNA genes. Nucleotide compositions of the whole mitogenome are 39.41% for A, 33.84% for T, 16.64% for C, and 10.11% for G. The AT and GC skewness of mitogenome sequence was 0.076 and -0.244, showing the A-skew and C-skew. The reconstructed phylogenetic relationships of 33 Curculionid species based on 13 mitochondrial protein-coding genes received absolute support (100%). Euwallacea fornicates is sister to the rest species in Xyleborini. The phylogenetic position of Scolytinae is sister to the clade including Cucurlioninae, Molytinae and Cryptorhynchinae. Mitogenomic data from this study will provide useful information for further studies for the population genetics, invasive history and pest control of E. fornicatus in the future.
