The mitochondrial genome of Lichtwardtia dentalis Zhang, Masunaga et Yang, 2009 (Diptera: Dolichopodidae)

Abstract

The long-legged fly Lichtwardtia dentalis Zhang, Masunaga et Yang, 2009 belongs to the subfamily Dolichopodinae of Dolichopodidae. The newly sequenced mitogenome of L. dentalis is a new representative of the subfamily. The nearly complete mitogenome is 15,124 bp in length, consisting of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes (rRNAs), and 22 transfer RNA genes (tRNAs). All genes have similar locations and encoding directions with that of other published mitogenomes of Dolichopodidae. The nucleotide composition biases toward A and T with the overall A þ T % is 73.9%. All protein-coding genes initiate with standard start codon ATN except COI and NAD1, and TAA/TAG are conventionally used as stop codons. All tRNAs, ranging from 62 to 71 bp, have a clover-leaf structure. Based on the result of the phylogenetic analysis, Dolichopodidae and Empididae were monophyletic, and the relationships among subfamilies of Dolichopodidae were Diaphorinae þ (Peloropeodinae þ (Xanthochlorinae þ (Medeterinae þ Dolichopodinae))). The monophyly of the subfamily Dolichopodinae and the sister relationship between Dolichopus and Lichtwardtia were also strongly supported.
