Structural and phylogenetic implications of the complete mitochondrial genome of Ledra auditura

We sequenced and annotated the first complete mitochondrial genome (mitogenome) of Ledra auditura (Hemiptera: Cicadellidae: Ledrinae) and reconstructed phylogenetic relationships among 47 species (including 2 outgroup species) on the basis of 3 datasets using maximum likelihood (ML) and Bayesian inference (BI) analyses. The complete L. auditura mitogenome (length, 16,094 bp) comprises 37 genes [13 protein-coding genes (PCGs), 22 tRNAs, and 2 rRNAs], 1 control region, and 2 long non-coding regions. The first long non-coding region (length, 211 bp) is located between tRNA-I and tRNA-Q and the second region (length, 994 bp) between tRNA-S2 and ND1. All PCGs show ATN (Met/Ile) as their start codon and TAR as their stop codon. Except tRNA-S1 (AGN), which lacks the dihydrouridine arm, all tRNAs can fold into the typical cloverleaf secondary structure. The complete L. auditura mitogenome shows a base composition bias of 76.3% A + T (A = 29.9%, T = 46.4%, G = 13.3%, and C = 10.5%), negative AT skew of -0.22, and positive GC skew of 0.12. In ML and BI analyses, L. auditura was clustered with Evacanthus heimianus (Hemiptera: Cicadellidae: Evacanthinae) with strong branch support.
