Abstract

A poorly known callianassid ghost shrimp species, Praedatrypaea modesta (De Man, 1905), is redescribed and illustrated based on new material recently collected off the south coast of Hainan Island, northern continental shelf of the South China Sea. Genetic data were obtained and compared with other six congeners. With the inclusion of this species, the monophyly of Praedatrypaea Poore, Dworschak, Robles, Mantelatto & Felder, 2019 is reevaluated. The inferred phylogenetic trees, based on two matrices (4-gene and 21-gene), both support the monophyly of this genus and its placement as sister taxon to all other genera of Callianassidae Dana, 1852.

不为人知的鬼虾Praedatrypaea modesta （De Man, 1905）的重新描述和系统发育位置（十足目：轴总目：虾科）。

根据最近在南海北部大陆架海南岛南海岸收集的新资料，对一种鲜为人知的虾科鬼虾——Praedatrypaea modesta （De Man, 1905）进行了重新描述和图解。获得了遗传数据，并对其他6个同源基因进行了比较。随着该物种的加入，preedatrypaea Poore, Dworschak, Robles, Mantelatto & Felder， 2019的单系性被重新评估。基于两个矩阵（4基因和21基因）推断的系统发育树都支持该属的单系性，并将其作为Callianassidae Dana， 1852的所有其他属的姐妹分类单元。

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
