Complete mitochondrial genomes and phylogenetic analysis of the Hawaiian planthoppers Iolania perkinsi and Oliarus cf. filicicola (Hemiptera: Cixiidae)

Abstract

We sequenced the complete mitochondrial genomes of one Iolania perkinsi (Kirkaldy 1902) and one Oliarus cf. filicicola (Kirkaldy 1909) planthopper (Hemiptera: Fulgoroidea: Cixiidae) from Volcano Village, located on the eastern flank of Mauna Loa. The I. perkinsi complete mitogenome is 14,949 bp in length and contains 13 protein-coding genes, 22 tRNAs and 2 rRNAs. The O. cf. filicicola nearly complete mitogenome is 15,196 bp in length due to an expanded (but incomplete) control region, and contains all of the typical metazoan genes: 13 protein-coding genes, 22 tRNAs and two rRNAs. Relative to the inferred ancestral gene order of insect mitochondrial genomes, no rearrangements were identified in either species. In addition to the shorter control region in I. perkinsi, the differences between the two mitogenomes consist of longer cox1, cox2, cob, nad1, nad5, nad6 genes but shorter nad4 gene in I. perkinsi relative to O. cf. filicicola. These mitogenomes represent the first sequences from species within the Hawaiian Cixiidae. The sequence data here will provide a foundation for continued studies of speciation patterns and dynamics of evolutionary radiation across Hawaiian planthoppers.
