Abstract:
To investigate the phylogenetic position of Isomyia Walker, 1860, a genus that suffered from frequent revisions of the taxonomic status following the subfamily Rhiniinae (Diptera, Calliphoridae), we sequenced, assembled, annotated, and analyzed the first complete mitochondrial genome (mitogenome) of Isomyia nebulosa (Townsend, 1917) in this study. This mitogenome is 16,438 bp in length, with a standard set of 13 protein-coding genes (PCGs), 22 tRNAs, two rRNAs, and an A + T riched non-coding region without genetic rearrangement as most dipteran mitogenomes, but long intergenic nucleotides (IGNs) between trnQ and trnM are found. The phylogeny yielded by both Bayesian inference and maximum-likelihood analysis for all mitochondrial PCGs and rRNAs of 23 mitogenomes supports the monophyly of the family Calliphoridae and the subfamilies Calliphorinae, Chrysomyinae, and Luciliinae. In addition, I. nebulosa diverged anterior to the above-mentioned three calliphorid subfamilies with high genetic distances.
