Abstract
This paper describes a new genus of Aradidae from China: Parayangiella gen. n., with its type species Parayangiella latiovatusa sp. n. Their diagnostic morphological characteristics are presented with illustrations, and molecular analyses are conducted. In addition, based on the sequence data of 13 protein-coding genes (PCGs), this study employed two methods-maximum likelihood (ML) and Bayesian inference (BI)-to construct the phylogenetic tree. The results are as follows: The mitochondrial genome of Parayangiella latiovatusa is a closed circular double-stranded structure, consisting of 13 protein-coding genes, a control region, 22 tRNA genes and 2 rRNA genes, which is consistent with most species in the family Aradidae. The mitochondrial genome of Parayangiella latiovatusa sp. n. exhibits AT skew. The phylogenetic tree construction results show that Parayangiella latiovatusa sp. n. and the genus Yangiella form a sister group.
