Abstract
The complete mitogenome of the Cydno Longwing Heliconius cydno has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 15,367 bp in length, and consists of 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs) and 1 D-loop region. PCGs are mostly initiated with the ATN codons (COII, COIII, Cytb, ND2, ND3, ND4, ND4L, ND5, ND6, ATP6 & ATP8), except for the ND1 and COI genes with TTG and the unusual CGA as their initiation codons, respectively. Some PCGs harbor TAG (ND3) or incomplete termination codon T (COI, COII & ND4), while all the others use TAA as their termination codons. The nucleotide composition is highly asymmetric (39.3% A, 42.1% T, 7.6% G, 11.0% C) with an overall GC content of 18.6%.
