Abstract
The mitochondrial genome of Neochauliodes fraternus (Megaloptera: Corydalidae) is a circular molecule of 15,768 bp in length, containing 37 typical mitochondrial genes: 13 protein-coding genes (PCGs), 2 ribosomal RNAs, 22 transfer RNAs and a non-coding AT-rich region. Its gene order and arrangement are identical to the common type found in most insect mitogenomes. All PCGs start with a typical ATN codon except for the ND1 which uses TTG as its start codon; all PCGs terminate in the common stop codon TAA or TAG, except for the COI, COIII, ND3, ND5, ND4 and CYTB which use single T as their stop codons. The non-coding AT-rich region is 1031 bp long, located between rrnS and tRNAlle genes. It contains some structures of repeated motifs and microsatellite-like elements characteristic of the megaloptera.
