The complete mitochondrial genome of Tylorida striata (GenBank accession number MN615900) is 14,422 bp in length with a high AT bias of 71.73%. It contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA (rRNA) genes, and a putative control region. The gene order of T. striata was identical to other spider mitogenomes. Eleven tRNAs (trnW, trnY, trnC, trnD, trnG, trnL2, trnR, trnF, trnP, trnI, and trnL1) lose the TΨC-stems, whereas two tRNAs (trnS1 and trnS2) lack the dihydrouracil (DHU) arm. Phylogenetic tree based on concatenated amino acid sequences of 13 PCGs showed that T. striata is clustered with two Tetragnathidae species and recovered as sister of other two Tetragnathids.

All tRNAs have the typical cloverleaf structure except for trnS1 and the length of them range from 62 to 71 bp. Phylogenetic tree showed that P. temminckii was clustered with three Cerambycidae species, which agree with the traditional classification. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

The complete mitochondrial genome of Argiope ocula (GenBank accession number MN331657) is a circular molecule of 14,079 bp in length, comprising of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes, and a control region. Ten intergenic spacer regions and 19 reading frame overlaps were found in the mitogenome of A. ocula. Ten tRNAs (trnD, trnF, trnK, trnR, trnT, trnW, trnE, trnG, trnL1, and trnM) lacked the TΨC arm stem, whereas three tRNAs (trnA, trnS1, and trnS2) lost the dihydrouracil (DHU) arm. Phylogenetic analysis suggested that A. ocula had the closest evolutionary relationship with A. perforata. [ABSTRACT FROM AUTHOR]

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, trnS1, and trnS2) 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. [ABSTRACT FROM AUTHOR]

The complete mitogenome of Argiope perforata (GenBank accession number MK512574) is 14,032 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes, and an A + T-rich region. ATT, ATA, TTA, TTG were initiation codons and TAA, TAG, and T were termination codons. Ten tRNAs (trnD, trnW, trnL2, trnE, trnF, trnR, trnH, trnP, trnT, and trnL1) lacked the TΨC arm stem, while three tRNAs (trnA, trnS1, and trnS2) lost the dihydrouracil (DHU) arm. Phylogenetic tree based on 13 PCGs showed that A. perforata is closely related to Neoscona theisi, and clustered within Araneidae clade. [ABSTRACT FROM AUTHOR]

The complete mitogenome of Cyclosa japonica (GenBank accession number MK512575) is 14,687 bp in length, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes, and a putative control region. Its gene content and organization are identical with other spider mitogenomes. The overall base composition was as follows: A (35.61%), T (37.35%), C (10.87%), and G (16.18%), with an A + T bias (72.96%). Seven tRNAs (trnM, trnW, trnK, trnE, trnF, trnH, and trnT) lacked the TΨC arm stem, while two tRNAs (trnS1 and trnS2) lacked the dihydrouracil (DHU) arm. Phylogenetic tree based on concatenated amino acid sequences of 13 PCGs shows that C. japonica is closely related to Cyclosa argenteoalba, which accord with morphological classification.

The complete mitochondrial genome of the lynx spider Oxyopes hupingensis was characterized in this study. The circular genome is 15,078 bp in length (GenBank accession number MK518391), containing 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA genes, and a control region. Its gene direction and arrangement are identical to those of other spider mitogenomes. The overall base composition is 34.76% A, 43.11% T, 8.04% C, and 14.09% G, showing AT-rich feature (77.87%). Ten PCGs are initiated with typical ATN start codons, three genes (cox2, cox3, and nad4) begin with TTG. Nine PCGs stop with complete termination codon TAA and TAG, cox1, nad4, nad4L, and cob are terminated with T. Twenty-three reading frame overlaps and four intergenic regions were found in the mitogenome of O. hupingensis. Three tRNAs lack the dihydrouracil (DHU) arm, whereas eight tRNAs lose the TΨC arm stems. Phylogenetic tree based on concatenated amino acid sequences of 13 PCGs shows that O. hupingensis has a close phylogenetic relationship with Oxyopes sertatus and belongs to Oxyopidae.

The complete mitochondrial genome of a hunting spider Evarcha coreana was determined. The circular mitogenome is 14,333 bp in length (GenBank accession number MK381265), and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA genes, and a putative control region. The orientation and gene order of E. coreana are identical with other spider mitogenomes. The AT content of the overall base composition is 75.86%. Twenty-two genes were in the major strand and 15 genes were in minor strand. Five intergenic regions and 25 reading frame overlaps were found in the mitogenome of E. coreana. Seven tRNA genes lost the TΨC arm stems, whereas three tRNAs lacked the dihydrouracil (DHU) arm. The control region is 697 bp in length with an A + T content of 81.06%. ATA, ATT, TTA, and TTG were initiation codons, and TAA, TAG, and T were termination codons. Phylogenetic analysis was performed using 13 PCGs with other spiders of the family Salticidae and it was seen that E. coreana is closely related to Telamonia vlijmi and Plexippus paykulli.
