The complete mitogenome sequence of a subterranean pseudocrangonyctid amphipod, , was determined. The complete mitogenome of was 15,069 bp in length with the typical 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and a control region (CR). This is the first complete mitogenome sequence in the family Pseudocrangonyctidae. Interestingly, gene arrangements of most amphipod species were almost identical to the typical pan-crustacean ground pattern, whereas two PCGs, both of rRNAs and CR were translocated in . A maximum-likelihood tree, constructed based on 30 eumalacostracan mitogenomes, confirmed that is closely related to the crangonyctid and and supported the monophyly of the superfamily Crangonyctoidea.
确定了一种地下伪钩虾科(Pseudocrangonyctidae)双甲目动物的完整线粒体基因组序列。该物种的完整线粒体基因组长度为15,069碱基对,包含典型的13个蛋白质编码基因(PCGs)、22个转运RNA(tRNAs)、2个核糖体RNA(rRNAs)和一个控制区(CR)。这是伪钩虾科的首个完整线粒体基因组序列。有趣的是,大多数双甲目动物的基因排列与典型的泛甲壳动物基本模式几乎相同,而在该物种中有两个PCGs、rRNAs和CR均发生了易位。基于30个真软甲亚纲线粒体基因组构建的最大似然树证实,该物种与钩虾科的[具体物种1]和[具体物种2]密切相关,并支持钩虾总科(Crangonyctoidea)的单系性。
