Comparative Analysis of Seventeen Mitochondrial Genomes of Mileewinae Leafhoppers, Including the Unique Species Mileewa digitata (Hemiptera: Cicadellidae: Mileewinae) From Xizang, China, and New Insights Into Phylogenetic Relationships Within Mileewini.

ABSTRACT: The subfamily Mileewinae in China comprises one tribe (Mileewini), four genera (Ujna, Mileewa, Processina, Anzihelus), and 71 species, yet only 11 mitochondrial genomes have been published. This study aimed to elucidate ambiguous diagnostic traits in traditional taxonomy and examined phylogenetic relationships among genera by sequencing mitochondrial genomes from 16 species. The lengths of the mitochondrial genomes ranged from 14,532 to 15,280 bp, exhibiting an AT content of 77.2%-80.7%, indicative of AT bias. Each genome contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), and 2 ribosomal RNA genes (rRNAs). Notably, the genome of the Xizang endemic Mileewa digitata measures 15,280 bp, with an AT content of 80.7%, 10,941 bp of PCGs, and
