Abstract
The complete mitochondrial genome (mitogenome) of Linnaeus Eurema hecabe (Lepidoptera: Pieridae: Coliadinae) is determined to be 15,160 bp in length, including 37 typical mitochondrial genes and an AT-rich region. Its gene order and orientation are identical to those of other butterfly species. All PCGs are initiated by typical ATN codons, except for CO1 gene which is started by CAG codon. Nine genes use complete termination codon (TAA), whereas the CO1, CO2, ND4 and ND5 genes end with single T. The two rRNA genes (rrnL and rrnS) are 1322 and 832 bp respectively; except for trnS1(AGN), all tRNA genes display typical secondary cloverleaf structures as those of other insects. The 315 bp long AT-rich region contains several features common to the other lepidopterans, such as the ATAGA motif followed by a 19 bp poly-T stretch, two microsatellite-like (TAA)5 and (AT)6 elements, a 9 bp poly-A stretch immediately upstream of trnM gene.
