Characterization of the complete mitochondrial genome and phylogenetic analysis of Leucauge celebesiana (Araneae: Tetragnathidae).

The complete mitogenome of Leucauge celebesiana (GenBank accession number MN296353) is 13,901 bp in size, and harbours 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs, and an A + T-rich region. The base composition of the mitogenome comprised A (33.80%), C (8.82%), G (14.42%), and T (42.96%), with a total A + T content of 76.76%. Eleven tRNAs (trnK, trnP, trnL1 , trnD, trnF, trnG, trnH, trnR, trnT, trnW, and trnV) lacked the TΨC arm stem, while three tRNAs (trnA, trnS1 , and trnS2 ) lost the dihydrouracil (DHU) arm. Phylogenetic analysis suggests that L. celebesiana has a close phylogenetic relationship with Tetragnatha maxillosa, which agree with the traditional taxonomy.
