Abstract
The complete mitochondrial genome (mitogenome) of Callerebia suroia (Lepidoptera: Nymphalidae: Satyrinae) was determined and analyzed in this paper. The circular genome is 15,208 bp long, including 37 typical mitochondrial genes and one non-coding AT-rich region. All protein-coding genes (PCGs) started with ATN, except for COI gene with CGA(R), which is often found in other butterflies; nine PCGs harbor the typical stop codon TAA, whereas COI, COII, ND5 and ND4 end with a single T. All tRNA genes display typical secondary clover-leaf structures, except for tRNASer(AGN), whose dihydrouridine (DHU) arm is replaced by a simple loop. The lrRNA and srRNA genes are 1,347 bp and 753 bp in length, with their AT contents of 84.4% and 85.4%, respectively. The 417 bp AT-rich region contains non repetitive sequences, but harbor several features common to the lepidopterans, including the motif ATAGA followed by a 19-bp poly-T stretch and a microsatellite-like (TA)8 element preceded by the ATTTA motif.
