          Abstract

          The complete mitochondrial genome of Pisaura bicornis (GenBank accession number MN296112) is 15,281 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes, and a putative control region. The overall base composition of this genome is A (35.65%), C (8.12%), G (13.47%) and T (42.76%), demonstrating an obvious bias of high AT content (73.2%). ATT, ATA, TTG were initiation codons and TAA, TAG, and T were termination codons. Ten tRNAs ( trnD, trnF, trnG, trnH, trnK, trnP, trnR, trnT, trnY, and trnE) lacked the TΨC arm stem, while three tRNAs ( trnA, trnS 1 , and trnS 2 ) lost the dihydrouracil (DHU) arm. Phylogenetic tree based on 13 PCGs showed that P. bicornis is closely related to Dolomedes angustivirgatus and belongs to Pisauridae.

          The complete mitochondrial genome of the orb-weaving spider Neoscona theisi (Walckenaer) (Araneae: Araneidae).

          The complete mitochondrial genome of an orb-weaving spider Neoscona theisi (Walckenaer) is determined in this article. It is a typical circular duplex DNA molecule with a length of 14,156 bp, which encodes the same 37 genes as all metazoan mitogenomes and an A + T-rich region (D-loop). The overall A + T content is 75.2% (A: 35.5%; T: 39.8%; G: 15.6%; C: 9.3%). All of the protein-coding genes were initiated by ATN, with the exceptions in three genes. COI has a TTA start codon, COII, COIII and ND6 use TTG as initiation codon. Three genes (ND3, COII and ND5) end with incomplete stop codons (T or TA), while all other genes terminated with canonical stop codons (TAA or TAG). Among 22 transfer RNAs genes, six of them (tRNAAla, tRNASer(AGN), tRNASer(UCN), tRNAGly, tRNAArg and tRNAHis) lack the potential to form the cloverleaf-shaped secondary structure. The A + T-rich region is 559 bp with an A + T content of 79.6%.
