(2017) Complete mitochondrial genomes determined. As reported for other cockroach mitogenomes, the two mitogenomes possessed of two blattid cockroaches, Periplaneta australasiae and Neostylopyga rhombifolia, and phylogenetic typical ancestral insect mitogenome gene composition and arrangement. Only several small relationships within the Blattaria.

Three different types of short tandem Editor: Xiu-Qing Li, Agriculture and Agri-Food repeats in the N. rhombifolia control region (CR) were observed. The homologous alignments Canada, CANADA of these tandem repeats with other six cockroach mitogenome CRs revealed a low similarity.
