摘要

Bathypalaemonella liui sp.nov.与 B. hayashi Komai, 1995 和 B. serratipalma Pequegnat, 1970 最为相似，其主要的第二节脊椎动物的屈肢边缘有一排小瘤。将本新种与 B. hayashi 和 B. serratipalma 区分开来的重要形态特征是喙的长度，它远远超过了胛骨，以及后三个脚足的双足，它们只带有一对附属棘。此外，所分析的这两个同源种的 COI 和 16S rRNA 基因的遗传差异也明确支持这一新分类群。

A new species of the genus Bathypalaemonella Balss, 1914 (Caridea, Bathypalaemonellidae) from a seamount in the South China Sea

A new species of deep-sea shrimp, Bathypalaemonella liui sp. nov., is described from the seamount of the South China Sea at a depth of 759–1117 m. Bathypalaemonella liui sp. nov. is most similar to B. hayashi Komai, 1995 and B. serratipalma Pequegnat, 1970 for the flexor margin of the major second pereopod bearing a row of tubercles. Important morphological characters which differentiate the present new species from B. hayashi and B. serratipalma are the length of the rostrum, which is far exceeding the scaphocerite, and the dactylus of the posterior three pereopods, which only bear one pair of accessory spines. Moreover, the genetic divergences of the COI and 16S rRNA genes from these two congeners analysed, clearly support the new taxon.
