ABSTRACT
Clubiona Latreille, 1804 comprises 503 species across the world, of which 122 species were reported from China. Nearly one-third of Chinese species have been described with single-sex (World Spider Catalog, 2018). Twenty-eight species have been reported from Guizhou Province (Wang et al. 2015; Wu et al. 2015; Li Lin 2016; Yu et al. 2017; Wang et al. 2018; Zhang et al. 2018).

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
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.
ABSTRACT
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
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.
ABSTRACT
The bamboo snout beetle Cyrotrachelus buqueti (Coleoptera: Curculionidae) is a destructive forest pest and distributed widely in Southeast Asia. The 15,035 bp complete mitochondrial genome of the species consists of 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 21 transfer RNA genes (tRNAs) and a control region (GenBank accession no. MG674390). The trnl gene was not found in the C. buqueti mitogenome. The gene order and the orientation of C. buqueti were similar to those found in other Coleoptera species. The nucleotide composition was significantly biased (A, G, C, and T was 38.18%, 10.10%, 16.16%, and 35.56%, respectively) with A + T contents of 73.74%. ATG, ATA, ATT, AAT, and TTG were initiation codons and TAA, TAG, and T were termination codons. All the 21 tRNAs displayed a typical cloverleaf secondary structure, except for trnS1 which lacked the dihydrouridine arm. Phylogenetic analysis was performed using 13 PCGs with 14 other beetles showed that C. buqueti is closely related to Eucryptorhynchus brandti, which agree with the traditional classification.
