Four new species of the primitively segmented spider genus Qiongthela from Hainan Island, China (Mesothelae, Liphistiidae)

Abstract

<jats:p>The primitively segmented spider genus <jats:italic>Qiongthela</jats:italic> Xu &amp;amp; Kuntner, 2015 consists of seven species that are distributed in Hainan Island, China and southern Vietnam. Of the seven species, five are known from Hainan Island. In this study, four more <jats:italic>Qiongthela</jats:italic> species collected from Hainan Island are diagnosed and described as new to science based on morphological characters: <jats:italic>Q. baoting</jats:italic><jats:bold>sp. nov.</jats:bold> (♂♀), <jats:italic>Q. qiongzhong</jats:italic><jats:bold>sp. nov.</jats:bold> (♂♀), <jats:italic>Q. sanya</jats:italic><jats:bold>sp. nov.</jats:bold> (♂♀), <jats:italic>Q. yinggezui</jats:italic><jats:bold>sp. nov.</jats:bold> (♂♀). To facilitate future identification, the GenBank accession codes of the DNA barcode gene, cytochrome c oxidase subunit I (COI), for all the type specimens are also provided.</jats:p>
