The complete mitochondrial genome of Dicraeus orientalis Becker, 1911 (Diptera: Chloropidae)

Abstract

Dicraeus orientalis feeds on the seeds of Poaceae. The complete mitochondrial genome of D. orientalis was sequenced and annotated as the first representative of the family Chloropidae. The full length of mitogenome was 16,188 bp, consisting of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), and two ribosomal RNA genes (rRNAs). The nucleotide composition was highly A þ T biased, accounting for 79.1% of the whole mitogenome. All PCGs start with ATN codons except COI, which end with TAN or incomplete stop codon. ML analysis revealed that Carnoidea was closely related to Ephydroidea and the phylogenetic relationship within Acalyptratae was Tephritoidea þ ((Carnoidea þ Ephydroidea) þ Opomyzoidea).

Comparative Analysis of the Mitochondrial Genomes of Chloropidae and Their Implications for the Phylogeny of the Family

“…Mitochondrial genomes have been widely used for phylogenetic inference for various taxonomic lineages of dipterans [ 30 , 31 , 32 ] because of their typically uniparental inheritance, lack of introns, high copy numbers, relatively simple structure, conserved gene composition, and rapid evolutionary rate [ 30 ]. However, limited attention has been given to individual chloropid mitochondrial genomes, with studies focusing primarily on Anatrichus pygmaeus [ 33 ], Chlorops oryzae [ 34 ], and Dicraeus orientalis [ 35 ]. This lack of data hinders a comprehensive phylogenetic analysis of Chloropidae.…”
