Two specimens of a species herein identified as Holothuria (Lessonothuria) insignis Ludwig, 1875 and a single specimen identified as Holothuria (Lessonothuria) lineata Ludwig, 1875, were collected from the intertidal zone at low tide from two coastal localities in Karachi (Buleji and Sunahri). This paper briefly documents their morphology and habitat characteristics and formally resurrects H. (L.) insignis from the synonymy of H. (L.) pardalis Selenka, 1867, based on the observations of the ossicles assemblage deduced from current material, syntype, some material at the NHMUK (Natural History Museum,UK), and literature. H. pardalis is also commented on and compared with its related congeners in Pakistan, in tabular form. A key is presented of all species of the Lessonothuria group currently recognized in WoRMS.
两个被鉴定为本论文中所述的1875年路德维希所命名的 insignis海参（Lessonothuria属）标本，以及一个被鉴定为1875年路德维希所命名的 lineata海参（Lessonothuria属）标本，是在卡拉奇两个沿海地区（布勒吉和苏纳赫里）的低潮期潮间带采集到的。本文简要记录了它们的形态和栖息地特征，并根据从现有材料、模式标本、英国自然历史博物馆（NHMUK）的一些材料以及文献中推断出的骨片组合观察结果，正式将 insignis海参（Lessonothuria属）从1867年塞伦卡所命名的pardalis海参（Lessonothuria属）的同物异名中重新提出。本文还以表格形式对pardalis海参（Lessonothuria属）进行了评论，并将其与其在巴基斯坦的相关同属物种进行了比较。本文还给出了世界海洋物种登记册（WoRMS）目前认可的Lessonothuria属所有物种的检索表。
