Abstract

To date, only two whip spider species have been recorded in China. We describe a new species, Sarax sinensis sp. nov., from Fujian, China. This species is morphologically similar to S. ioanniticus (Kritscher, 1959), S. israelensis (Miranda et al., 2016), and S. seychellarum (Kraepelin, 1898), but can be distinguished by the combination of the following characters: 35 segments in leg I tarsus, eight teeth on cheliceral claw, and four dorsal and ventral spines respectively on pedipalp femur. To examine the evolutionary history of S. sinensis sp. nov., we sequenced 12S, 16S, and COI gene regions of our specimens and inferred its phylogenetic position. The inferred phylogenetic trees placed the new species within Sarax, with its closest relative being distributed across the western Asia. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).

摘要

截至目前，中国仅记录了两种鞭蛛。我们描述了一种来自中国福建的新物种，中华鞭蛛 Sarax sinensis sp. nov.。该物种在形态上与伊奥安尼特鞭蛛 Sarax ioanniticus (Kritscher, 1959)、以色列鞭蛛 Sarax israelensis (Miranda et al., 2016) 和塞舌尔鞭蛛 Sarax seychellarum (Kraepelin, 1898) 相似，但可以通过以下特征组合来区分：步足 I 跗节 35 节，螯肢爪 8 齿，触肢股骨分别有 4 根背刺和腹刺。为了研究中华鞭蛛 Sarax sinensis sp. nov. 的进化历史，我们对标本进行了 12S、16S 和 COI 基因区域的测序，并推断了其系统发育位置。推断的系统发育树将新物种置于 Sarax 内，其最接近的亲缘种分布在西亚。模式标本存放在华东师范大学生物博物馆（ECNU）。
