A new species of Dalyelliidae, Wang and You, is described based on material collected in southern China through an integrative approach combining morphological, histological, and molecular (18S and 28S rDNA) data. sp. nov. is morphologically characterized by a fan-shaped (about 270° when pressed) stylet, consisting of 13 similar distal spines and a broad girdle without fenestrae region. This stylet is distinct from that of any other similar species in the Aequales group to which this species belongs. In addition, specimens identifiable as Van Steenkiste, Van Mulken, and Artois, 2012 were discovered from the same location as sp. nov. has previously been known only from India; the present study thus represents the first record of the species from China.
一种新的 Dalyelliidae 物种，Wang 和 You 根据在中国南方通过结合形态学、组织学和分子（18S 和 28S rDNA）数据的综合方法采集的材料进行描述。sp. nov. 的形态特征为扇形（按压时约 270°）的口针，由 13 个相似的远端刺和一个宽阔的环带组成，没有窗区。这种口针与该种所属的 Aequales 组的任何其他类似种的口针都不同。此外，在与 sp. nov. 相同的地点发现了与 Van Steenkiste、Van Mulken 和 Artois，2012 可识别的标本。Van Steenkiste、Van Mulken 和 Artois，2012 以前仅在印度被发现；本研究代表了该物种在中国的首次记录。
