The complete mitochondrial genome of (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 was identical to other spider mitogenomes. Eleven tRNAs (, , , , , , , , , , and ) lose the TΨC-stems, whereas two tRNAs ( and ) lack the dihydrouracil (DHU) arm. Phylogenetic tree based on concatenated amino acid sequences of 13 PCGs showed that is clustered with two Tetragnathidae species and recovered as sister of other two Tetragnathids.
（GenBank登录号MN615900）的完整线粒体基因组长度为14422 bp，AT偏倚率较高，为71.73%。它包含13个蛋白质编码基因（PCGs）、22个转运RNA基因（tRNAs）、2个核糖体RNA（rRNA）基因和一个假定的控制区。其基因排列顺序与其他蜘蛛线粒体基因组相同。11个tRNA（、、、、、、、、、和）失去了TΨC茎，而2个tRNA（和）缺少二氢尿嘧啶（DHU）臂。基于13个PCG串联氨基酸序列构建的系统发育树表明，与两种肖蛸科物种聚类，并被确定为其他两种肖蛸科物种的姐妹种。
