The mitochondrial genome of a minute springtail species Megalothorax incertus (Collembola: Neelipleona: Neelidae)

In this study, the complete mitochondrial genome for the Wolbachia infected parthenogenetic collembola Megalothorax incertus Börner, 1903 was determined. It represents the first report of a complete mitochondrial genome from Neelipleona, one of the four orders of Collembola. The circularized 14,994 bp mitochondrial genome sequence consists of canonical 37 mito-genes, including 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes. The base composition of the majority strand (same direction as most of the mitochondrial genes) is 32.0% for A, 24.1% for C, 11.9% for G, and 32.1% for T. The phylogenetic trees inferred from 13 PCGs using the Maximum-likelihood (ML) and Bayesian inference (BI) methods suggested that Neelidae is basal to the remaining springtails. This mitochondrial genome provides new insights to decipher the phylogeny of Collembola.
