The complete mt genome of a fishfly species, Dysmicohermes ingens (Megaloptera: Corydalidae: Chauliodinae), was sequenced. The 16,271 bp long genome has the standard metazoan complement of 37 genes and an A+T-rich region, in the insect ancestral genome arrangement. All protein coding genes (PCGs) initiate with ATN except that cox1 initiates with CGA and nad1 initiates with TTG. This is the first report that cox1 uses CGA as the start codon in Neuropterida. The control region occupying 1495 bp is comparatively simple, with no conserved blocks or long tandem repeats.
Keywords: Control region; Dysmicohermes ingens; mitochondrial genome; start codon.
